We study the radiation reaction in Lorentz-violating electrodynamics [D. Colladay and V. Alan Kostelecky, Phys. Rev. D 58, 116002 (1998)]. We explore the possible modification whatsoever present in the radiation reaction force experienced by an accelerating charge in the modified Maxwell theory. However, it turns out that radiation reaction receives no change due to Lorentz violation, whereas electromagnetic mass manifests anisotropy.

Abstract:
ABSTRACT Strongly magnetized and fast-rotating neutron stars are known to be efficient particle accelerators within their magnetosphere and wind. They are suspected to accelerate leptons, protons, and maybe ions to extreme relativistic regimes where the radiation reaction significantly feeds back to their motion. In the vicinity of neutron stars, magnetic field strengths are close to the critical value of Bc ∼ 4.4 · 109 T and particle Lorentz factors of the order γ ∼ 109 are expected. In this paper, we investigate the acceleration and radiation reaction feedback in the pulsar wind zone where a large-amplitude low-frequency electromagnetic wave is launched starting from the light cylinder. We design a semi-analytical code solving exactly the particle equation of motion including radiation reaction in the Landau–Lifshits approximation for a null-like electromagnetic wave of arbitrary strength parameter and elliptical polarization. Under conventional pulsar conditions, asymptotic Lorentz factor as high as 108−109 is reached at large distances from the neutron star. However, we demonstrate that in the wind zone, within the spherical wave approximation, radiation reaction feedback remains negligible.

Full text
Abstract:
The principle of equivalence is shown to extend to situations involving radiation reaction. For example, the Lorentz force law governs the motion of an isolated charge undergoing radiation reaction. In the case of an isolated uncharged particle of small mass, it is the geodesic equation which governs the motion, even when radiation reaction is included. For a local observer to understand such motion he must subtract the singular field of the particle from the actual electromagnetic and gravitational fields he measures. The remaining source-free fields are then used in computing the motion of the particle. With only local measurements, the observer has no knowledge of the existence of radiation and sees no effect which he would be compelled to describe as radiation reaction.

Abstract:
Nonlinear phenomena caused by the quadratic interaction of electromagnetic waves in a dense charged medium (Coulomb systems, plasma) are considered: parametric generation and generation of the second harmonic of electromagnetic radiation. To determine the quadratic reaction functions describing the interaction of electromagnetic waves in the medium, an approach based on the use of explicit approximations for reaction functions with fitting parameters is applied. Parameters are found from the exact frequency moments of the reaction functions. Using data on reaction functions, the conditions for the experimental implementation of these phenomena in a laboratory dense plasma in a constant magnetic field were evaluated.

Abstract:
Electromagnetic Radiation is a graduate level book on classical electrodynamics with a strong emphasis on radiation. This book is meant to quickly and efficiently introduce students to the electromagnetic radiation science essential to a practicing physicist. While a major focus is on light and its interactions, topics in radio frequency radiation, x-rays, and beyond are also treated. Special emphasis is placed on applications, with many exercises and homework problems. The format of the book is designed to convey the basic concepts of a topic in the main central text in the book in a mathematically rigorous manner, but with detailed derivations routinely relegated to the accompanying side notes or end of chapter “Discussions.” The book is composed of four parts: Part I is a review of basic E&M, and assumes the reader has a had a good upper division undergraduate course, and while it offers a concise review of topics covered in such a course, it does not treat any given topic in detail; specifically electro- and magnetostatics. Part II addresses the origins of radiation in terms of time variations of charge and current densities within the source, and presents Jefimenko’s field equations as derived from retarded potentials. Part III introduces special relativity and its deep connection to Maxwell’s equations, together with an introduction to relativistic field theory, as well as the relativistic treatment of radiation from an arbitrarily accelerating charge. A highlight of this part is a chapter on the still partially unresolved problem of radiation reaction on an accelerating charge. Part IV treats the practical problems of electromagnetic radiation interacting with matter, with chapters on energy transport, scattering, diffraction and finally an illuminating, application-oriented treatment of fields in confined environments.

Abstract:
This chapter considers unimolecular reactions; photo-induced reactions, that is, true unimolecular reactions; and reactions initiated by collisional activation, that is, apparent unimolecular reactions where it is assumed that the time scales for activation and subsequent reaction are well separated. Elements of classical and quantum dynamical descriptions are discussed, including Slater theory and the quantum mechanical description of photo-induced reactions. Statistical theories aiming at the calculation of micro-canonical as well as canonical rate constants are discussed, including a detailed discussion of RRKM theory. It concludes with a discussion of femtochemistry, that is, the observation and control of chemical dynamics using femtosecond pulses of electromagnetic radiation, focusing on the control of unimolecular reactions via the interaction with coherent light; that is, laser control.

Abstract:
This chapter discusses six diseases caused by inborn errors of metabolism affecting the biosynthesis of haem. Haem is a tetracyclic metal-binding compound involved in oxygen transport (in haemoglobin and myoglobin) and redox reactions (e.g. in the cytochrome P450 system). Each of these conditions is caused by a single gene defect in one of the enzymes involved in the biosynthesis of haem. Inheritance is usually autosomal dominant with incomplete penetrance. The enzyme defect results in disease, not as a result of deficiency of the reaction product, but as a result of accumulation of precursors. Early, soluble precursors, 5-aminolaevulinic acid, and porphobilinogen (not porphyrins as such) are neurotoxic and, when present in great excess, as occurs when flux through the haem synthetic pathway is increased in response to particular medications or hormones, lead to acute neurovisceral crises. Later cyclical precursors (porphyrins) in the pathway are also water soluble and excreted in urine, but are susceptible to activation by electromagnetic radiation in the visible spectrum and are converted to free-radical metabolites that cause pain, inflammation, and tissue damage in the skin. The final haem precursors (also porphyrins) are hydrophobic and excreted in the bile and faeces and are also activated by light to toxic metabolites.

Abstract:
Most experimental techniques addressed in the present book are suitable for investigating the thermochemistry of thermally activated reactions, that is, those reactions whose activation barrier can be overcome by increasing the thermal energy of the reactants. This thermal energy, which is the average sum of molecular translational, rotational, and vibrational energies, can be changed by varying the temperature of the reactants. Some chemical reactions, however, do not occur by thermal activation. They require larger energy inputs—big enough to raise the electronic energy of at least one of the reactants and even induce the cleavage of a chemical bond. This “surgical” energy promotion is only attainable by electromagnetic radiation with a suitable wavelength. Visible light (420–700 nm) or ultraviolet radiation are typically used because the energies involved are in the same range of electronic excitation energies and of bond dissociation enthalpies, for example, a 700 nm photon corresponds to an energy of 170.9 kJ mol−1 (see conversion factors in appendix A). The reactions initiated by electromagnetic radiation are said to be photochemically activated. Note that only the initiation step may require the absorption of one or more photons (a photochemical reaction). Subsequent steps of the mechanism may be “dark reactions,” proceeding by thermal activation. The thermochemical study of photochemical or photochemically activated processes is not amenable to most of the calorimeters described in this book, simply because they do not include a suitable radiation source or the necessary auxiliary equipment to monitor the electromagnetic energy absorbed by the reaction mixture. However, it is not hard to conceive how a calorimeter from any of the classes mentioned in chapter 6 (adiabatic, isoperibol, or heat flow) could be modified to accommodate the necessary hardware and be transformed into a photocalorimeter. A general discussion of the basic principles of photocalorimetry, which we closely follow in the ensuing discussion, was made by Teixeira and Wadsö [179]. An amount of radiant energy E is supplied to the calorimetric cell and absorbed by the reaction mixture, initiating a chemical reaction.

Abstract:
The first step in a unimolecular reaction involves energizing the reactant molecule above its decomposition threshold. An accurate description of the ensuing unimolecular reaction requires an understanding of the state prepared by this energization process. In the first part of this chapter experimental procedures for energizing a reactant molecule are reviewed. This is followed by a description of the vibrational/rotational states prepared for both small and large molecules. For many experimental situations a superposition state is prepared, so that intramolecular vibrational energy redistribution (IVR) may occur (Parmenter, 1982). IVR is first discussed quantum mechanically from both time-dependent and time-independent perspectives. The chapter ends with a discussion of classical trajectory studies of IVR. A number of different experimental methods have been used to energize a unimolecular reactant. Energization can take place by transfer of energy in a bimolecular collision, as in . . . C2H6 + Ar → C2H6* + Ar . . . . . . (4.1) . . . Another method which involves molecular collisions is chemical activation. Here the excited unimolecular reactant is prepared by the potential energy released in a reactive collision such as . . . F + C2H4 → C2H4F* . . . . . . (4.2) . . . The excited C2H4F molecule can redissociate to the reactants F + C2H4 or form the new products H + C2H3F. Vibrationally excited molecules can also be prepared by absorption of electromagnetic radiation. A widely used method involves initial electronic excitation by absorption of one photon of visible or ultraviolet radiation. After this excitation, many molecules undergo rapid radiationless transitions (i.e., intersystem crossing or internal conversion) to the ground electronic state, which converts the energy of the absorbed photon into vibrational energy. Such an energization scheme is depicted in figure 4.1 for formaldehyde, where the complete excitation/decomposition mechanism is . . . H2CO(S0) + hν → H2CO(S1) → H2CO*(S0) → H2 + CO . . . . . . (4.3) . . . Here, S0 and S1 represent the ground and first excited singlet states.

Abstract:
Incorporation of dopants efficiently in semiconductors at the nanoscale is an open challenge and is also essential to tune the conductivity. Typically, heating is a necessary step during nanomaterials’ solution growth either as pristine or doped products. Usually, conventional heating induces the diffusion of dopant atoms into host nanocrystals towards the surface at the time of doped sample growth. However, the dielectric heating by microwave irradiation minimizes this dopant diffusion problem and accelerates precursors’ reaction, which certainly improves the doping yield and reduces processing costs. The microwave radiation provides rapid and homogeneous volumetric heating due to its high penetration depth, which is crucial for the uniform distribution of dopants inside nanometer-scale semiconducting materials. This chapter discusses the effective uses of microwave heating for high-quality nanomaterials synthesis in a solution where doping is necessary to tune the electronic and optoelectronic properties for various applications.

Abstract:
Electromagnetic radiation in the form of UV and visible light has long been used as a reactant in inorganic reactions. The energy of light in the 200- to 800-nm region varies between 143 and 36 kcal mol-1, so it is not surprising that chemical bonds can be affected when a system absorbs light in this readily accessible region. Systematic mechanistic studies in this area have benefited greatly from the development of lasers that provided intense monochromatic light sources and from improvements in actinometers to measure the light intensity. Prior to the laser era, it was necessary to use filters to limit the energy of the light used to a moderately narrow region or to just cut off light below a certain wavelength. Pulsed-laser systems also allow much faster monitoring of the early stages of the reaction and the detection of primary photolysis intermediates. The systems discussed in this chapter have been chosen because of their relationship to substitution reaction systems discussed previously. For a broader assessment of this area, various books and review articles should be consulted. Mechanistic photochemistry incorporates features of both electron-transfer and substitution reactions, but the field has some of its own terminology, which is summarized as follows: The quantum yield,F , is the number of defined events, in terms of reactant or product, that occur per photon absorbed by the system. An einstein, E, is defined as a mole of photons, and if n is the moles of reactant consumed or product formed, then F = n/E. For simple reactions F£ 1 but can be >1 for chain reactions. An actinometer is a device used to measure the number of einsteins emitted at a particular wavelength by a particular light source. Photon-counting devices are now available and secondary chemical actinometers have been developed, such as that based on the Reineckate ion, Cr(NH3)2(NCS)4-, as well as the traditional iron(III)-oxalate and uranyl-oxalate actinometers. An early problem in this field was the lack of an actinometer covering the 450- to 600-nm range and the Reineckate actinometer solved this problem.

Abstract:
In the reaction zone of flame, electronically excited species are formed such as CH*, OH* etc. During de-excitation these radicals emit electromagnetic radiation of certain wavelength. This process is called chemiluminescence. The intensity of chemiluminescence, is in general captured using a photo multiplier tube (PMT), which is used to measure unsteady heat release rate from premixed flames. This technique is well established and is now a standard for unsteady heat release rate measurements in the parlance of combustion instability, however has certain limitations. In fuel rich mixtures, unreacted heated carbon emits broad band black body radiation, which in some cases large enough to mask the chemiluminescence signal. Hence, this technique is not valid for fuel rich conditions. Moreover, it cannot be applied, when the heat source is diffusion/partially premixed flames or electrically heated wires. We propose an alternative in this regard: two microphone technique. In this technique, we relate the acoustic velocity jump across the heat source to measure the unsteady heat release rate. The up and downstream acoustic velocity, in turn is obtained by two microphone technique. Experiments are performed in a premixed multiple flame burner at fuel lean conditions. This burner is enclosed in a duct, which acts as an acoustic resonator. Results indicate that the magnitude of the unsteady heat release rate obtained from both the techniques is found to agree within 18 %. Experiments are conducted for various lengths of the duct, thereby changing the oscillating frequency. This method is valid as long as the heat source is compact in comparison to the duct, which is true in most of the combustors during combustion instability and is irrespective of its type.
