Full textIn this thesis, after an introduction where we briefly present the general context of Casimir physics, we present the results obtained during the PhD. At first, we show our work about the van der Waals/Casimir-Polder interactions between two atoms in an out-of-equilibrium condition due to their uniformly accelerated motion. We study the system of two uniformly accelerated atoms in vacuum space, when they are in their ground-state and when they are in a correlated state (one excited and one ground-state atom). We analyze this system both with an heuristic semiclassical model and with a more rigorous method, based on a separation of radiation reaction and vacuum fluctuations contributions, that we extend starting from a general procedure known in literature. We find a change of the distance-dependence of the interaction due to the acceleration. We show that Casimir-Polder forces between two relativistic uniformly accelerated atoms, interacting with the scalar field, exhibit a transition from the short-distance thermal-like behavior predicted by the Unruh effect to a long-distance nonthermal behavior, associated with the breakdown of a local inertial description of the system. In addition, we obtain new features of the resonance interaction in the case of atoms interacting with the quantum electromagnetic field.Next, we present our work about a new optomechanical coupling of an effectively oscillating mirror with a Rydberg atoms gas, mediated by the dynamical atom-mirror Casimir-Polder force. We find that this coupling may produce a near-field resonant atomic excitation not related to the excitation of atoms by the few real photons expected by dynamical Casimir effect. In accessible experimental conditions, this excitation probability is significant (about 20%) making the observation of this new dynamical Casimir-Polder effect possible. For this reason, we propose a realistic experimental configuration to realize this system made of a cold atom gas trapped in front of a semiconductor substrate, whose dielectric properties are periodically modulated in time.Finally, we focus on our results obtained for the Casimir-Lifshitz pressure between two different dielectric lamellar gratings. This system is assumed to be in an out-of-thermal-equilibrium configuration, i.e. the two gratings have two different temperatures and they are immersed in a thermal bath having a third temperature. The computation of the pressure is based on a method exploiting the scattering operators of the bodies, deduced using the Fourier modal method. In our numerical results we characterize in detail the behavior of the pressure, both by varying the three temperatures and by changing the geometrical parameters of the gratings. In this way we show that it is possible to tune the force from attractive to repulsive or to strongly reduce the pressure for large ranges of temperatures. Moreover, we stress that the interplay between nonequilibrium effects and geometrical periodicity make this system particularly interesting for the observation of the repulsive Casimir force

Full textIn this thesis we describe measurements of selective reflection spectroscopy that highlight the thermal effects of the Casimir-Polder interaction between atom and surface. In the near field regime, this interaction is governed by a potential decreasing with the cube of the distance between the atom and the surface (van der Waals -vdW- regime of dipoledipole type) We are particularly interested in the excited levels of cesium, we are particularly interested in the excited levels of cesium Cs (7P₁/₂) and Cs (7P₃/₂), which have a dipole coupling to respectively Cs (6D) at 12,15 µm and ~15 µm interacting with a thermally emissive sapphire surface. Sapphire emitting modes are around 12,2 µm, and, thus, these Cs levels are sensitive to a resonant, or non-resonant, vdW interaction. We compare experimentally these levels. The most important result of this thesis is the experimental observation of the difference in behavior of the vdW potential as a function of the window temperature (150 - 800 °C), for the Cs (7P₁/₂) and Cs (7P₃/₂) levels. For the Cs (7P₁/₂) level the vdW potential increases as a function of temperature, while for the Cs (7P₃/₂) level a slight decrease is observed. Selective reflection spectroscopy experiments, probing the Cs (6P₁/₂) level interacting with a hot sapphire surface, were also carried out, which confirm for this level the absence of a temperature effect. The theoretical predictions are refined by the evaluation of the dielectric constant of sapphire as a function of temperature, from new emissivity data provided by the CEMHTI's group, in Orléans. Finally, we use backscattered fluorescence as a diagnosis for the Cs hot cell when exciting Cs (6P ₁/₂) and Cs (7P ₁/₂) levels. We have interpreted, in a manner more consistent than previous literature, sub-Doppler structures observed in the excitation of the fluorescence near the window

Full textThis thesis examines the properties of the interface between two phases in phase separated systems. We are interested in how finite size effects modify the statistical properties of these interfaces, in particular how the dependence of the free energy on the system size gives rise to long range critical Casimir forces close to thecritical point. Often the interfaces in phase separated systems are described by simplified or coarsegrained models whose only degrees of freedom are the interface height. We review how the statics and dynamics of these interface models can be derived from microscopic spin models and statistical field theories. We then examine finite size effects for continuous interface models such as the Edwards Wilkinson model and discrete models such as the Solid-On-Solid model and discuss their relevance to the critical Casimir effect. In the second part of the thesis we examine models of driven interfaces which have nonequilibrium steady states. We develop a model C type model of an interface which shows a nonequlibrium steady state even with constant driving. The resulting nonequlibrium steady state shows properties seen in experiments on sheared colloidal systems, notably the suppression of height fluctuations but an increase in the fluctuations’correlation length. Finally we propose a new model for one dimensional interfaces which is a modification of the solid on-solid model and containing an extra entropic term ,whose correspondance with physical systems is yet to be found

Full textque, en estos modelos, la separación entre la escala electrodébil y la de Planck
depende del tamaño de las dimensiones extra. Éste viene caracterizado por un
modo escalar de la métrica conocido como el radión, de forma que una solución
completa al problema de la jerarquía requiere algun mecanismo de estabilización
que fije su valor y explique por qué no se observan las interacciones escalares
transmitidas por el radión.
En esta tesis se estudia la posibilidad de que la energía de Casimir estabilice
el radión (proporcionandole una masa suficientement grande) y generen la
jerarquía de forma natural. Se argumenta que en modelos donde la geometría no
es factorizable, los efectos cuánticos proporcionan un mecanismo de
estabilización capaz de generar y estabilizar la jerarquía. En conctreto, se
discuten los efectos cuánticos en tres familias de modelos.
El primer ejemplo consiste en un modelo tensor--escalar en cinco dimensiones en
que el factor de 'warp' crece como una potencia de la distancia. La presencia de
una simetría de 'scaling' anómala permite estabilizar las posiciones de las branas
y generar la jerarquía de forma natural incluso para potencias pequeñas. No
obstante, las masas de los módulos es suficientemente grande cuando la potencia
del factor de warp es de orden 10 o mayor.
La segunda clase de modelos consiste en un espacio de más de 5 dimensiones donde el
espacio interno y las direcciones no compactas tienen un factor de warp
exponencial. En este modelo, la jerarquía se genera mediante una combinación de
los efectos de redshift y de volumen grande. Se encuentra que los efectos
cuánticos estabilizan las posiciones de las dos branas y generan la gerarquía de
forma natural si el espacio interno es plano.
En el tercer tipo de modelos, el espacio interno no tiene factor de warp y la
jerarqía se genera mediante el efecto de redshift. Al igual que en el modelo de
Randall Sundrum, la fuerza de Casimir debida a un campo de gauge en el bulk puede
estabilizar la jerarquía de forma natural.
Se concluye que en los modelos de branas con geometría no factorizable, los efectos
cuánticos son capaces de estabilizar la jerarquía naturalmente de forma relativamente
genérica.
Certain brane world scenarios can solve the hierarhy problem exploiting the fact that,
in these models, the separation between the electroweak and the Planck scales
--'the hierarchy'-- depends on the size of the extra dimensions. This size is
parmetrized by a scalar mode of the higher dimensional metric called 'the radion'.
Hence, a complete solution to the hierarchy problem requires a stabilization mechanism
that naturally fixes the radion at an appropriate value and explains why the interactions
mediated by such a scalar are not observed.
In this thesis, we consider the possibility that the Casinir energy is responsible for
stabilizing the radion and generating a large hierarchy in a natural way. We argue that,
in scenarios where the geometry is not factorizable, the quantum effects indeed can provide
a stabilization mechanism that generates naturally a large hierarchy. Specifically, we
discuss three classes of models.
The first example consists in a five dimensional scalar--tensor model bounded by two
parallel branes, where the warp factor grows like a power of the distance. The presence
of an anomalous scaling symmetry in the model allows to stabilize the moduli, which
correspond to the brane locations. A large hierarchy can be obtained even for low values
of the power. However, the generated masses for the moduli are large enough if the power
of the warp factor is of order 10 or bigger.
The second class of models consists in a space of more than five dimensions where the
additional internal space and the noncompact directions share an exponential warp factor.
In these models, the hierarchy is generated by a combination of the redshift effect and
the large volume effect. We find that the Casimir energy stabilizes the brane positions and
generate a large hierarchy if the internal space is flat.
In the third example, the internal space does not have a warp factor and the hierarhy is
generated by the redshift effect. As is the Randall Sundrum model, the Casimir force due
to a bulk gauge field can generate and stabilize a large hierarchy in a natural fashion.
We conclude that relatively generically, the quantum effects can naturally stabilize a
large hierarchy in models with a non factorizable geometry.

Full textThis thesis investigates the Casimir effect between plates made of normal and superconducting metals over a broad range of temperatures, as well as the Casimir-Polder interaction of an atom to such a surface. Numerical and asymptotical calculations have been the main tools in order to do so. The optical properties of the surfaces are described by dielectric functions or optical conductivities, which are reviewed for common models and have been analyzed with special weight on distributional properties and causality. The calculation of the Casimir energy between two normally conducting plates (cavity) is reviewed and previous work on the contribution to the Casimir energy due to the surface plasmons, present in all metallic cavities, has been generalized to finite temperatures for the first time. In the field of superconductivity, a new analytical continuation of the BCS conductivity to to purely imaginary frequencies has been obtained both inside and outside the extremely dirty limit of vanishing mean free path. The Casimir free energy calculated from this description was shown to coincide well with the values obtained from the two fluid model of superconductivity in certain regimes of the material parameters. The Casimir entropy in a superconducting cavity fulfills the third law of thermodynamics and features a characteristic discontinuity at the phase transition temperature. These effects were equally encountered in the Casimir-Polder interaction of an atom with a superconducting wall. The magnetic dipole coupling of an atom to a metal was shown to be highly sensible to dissipation and especially to the surface currents. This leads to a strong quenching of the magnetic Casimir-Polder energy at finite temperature. Violations of the third law of thermodynamics are encountered in special models, similar to phenomena in the Casimir-effect between two plates, that are debated controversely. None of these effects occurs in the analog electric dipole interaction. The results of this work suggest to reestablish the well-known plasma model as the low temperature limit of a superconductor as in London theory rather than use it for the description of normal metals. Superconductors offer the opportunity to control the dissipation of surface currents to a great extent. This could be used to access experimentally the low frequency optical response of metals, which is strongly connected to the thermal Casimir-effect. Here, differently from corresponding microwave experiments, energy and momentum are independent quantities. A measurement of the total Casimir-Polder interaction of atoms with superconductors seems to be in reach in today’s microchip-based atom-traps and the contribution due to magnetic coupling might be accessed by spectroscopic techniques
