Abstract:
The damping of the harmonic oscillator is studied in the framework of the Lindblad theory for open quantum systems. A generalization of the fundamental constraints on quantum mechanical diffusion coefficients which appear in the master equation for the damped quantum oscillator is presented; the Schrödinger, Heisenberg and Weyl-Wigner-Moyal representations of the Lindblad equation are given explicitly. On the basis of these representations it is shown that various master equations for the damped quantum oscillator used in the literature are particular cases of the Lindblad equation and that not all of these equations are satisfying the constraints on quantum mechanical diffusion coefficients. Analytical expressions for the first two moments of coordinate and momentum are obtained by using the characteristic function of the Lindblad master equation. The master equation is transformed into Fokker-Planck equations for quasiprobability distributions and a comparative study is made for the Glauber P representation, the antinormal ordering Q representation, and the Wigner W representation. The density matrix is represented via a generating function, which is obtained by solving a timedependent linear partial differential equation derived from the master equation. Illustrative examples for specific initial conditions of the density matrix are provided. The solution of the master equation in the Weyl-Wigner-Moyal representation is of Gaussian type if the initial form of the Wigner function is taken to be a Gaussian corresponding (for example) to a coherent wavefunction. The damped harmonic oscillator is applied for the description of the charge equilibration mode observed in deep inelastic reactions. For a system consisting of two harmonic oscillators the time dependence of expectation values, Wigner function and Weyl operator, are obtained and discussed. In addition models for the damping of the angular momentum are studied. Using this theory to the quantum tunneling through the nuclear barrier, besides Gamow’s transitions with energy conservation, additional transitions with energy loss are found. The tunneling spectrum is obtained as a function of the barrier characteristics. When this theory is used to the resonant atom-field interaction, new optical equations describing the coupling through the environment of the atomic observables are obtained. With these equations, some characteristics of the laser radiation absorption spectrum and optical bistability are described.

Abstract:
ABSTRACT To many, economics is seen as increasingly divorced from reality. I shall argue that one of the causes of this divorce is the attachment to closed-system theorising, and advocate instead the method of open systems with partial and temporary closures. Definitions of closed and open systems are examined. It is evident that there are many different criteria which may define open systems. Theorists differ in their emphasis on one or other criterion. There are also different dimensions of openness: openness to non-economic factors; the openness of economic theories themselves; the interplay of micro- and macro-economics; and the treatment of time. These are explored, using Keynes’s General Theory as a case study of an open system.

Abstract:
The Systems Theory Framework (STF) facilitates the inclusion of relevant aspects of multiple existing theories within an integrated framework, wherein relevance and meaning is decided upon by each individual. Patton and McMahon emphasise that the application of the Systems Theory Framework in integrating theory and practice is located within the crucible of the individual, acknowledging that the individual is an open system recursively interacting with and within multiple systems. The present paper furthers a discussion of the potential for the Systems Theory Framework in theory integration, in particular with respect to relational theories.

Abstract:
We study the barrier penetrability in the frame of the Lindblad theory of open quantum systems. In addition to the diagonal elements of the density matrix, leading to the Gamow’s formula, new terms, describing energy dissipation and spectral line broadening effects are obtained. It is shown that the presence of a dissipative environment increase the barrier penetrability, in accordance with a very simple physical interpretation: for a system initially found in its ground state the dissipation can lead only to transitions to the reaction channels where lower-energy levels exist.

Abstract:
Open quantum systems continually lose information to their surroundings. In some cases this information can be readily retrieved from the environment and put to good use by engineering a feedback loop to control the system dynamics. Two cases are distinguished: one where the feedback mechanism involves a measurement of the environment, and the other where no measurement is made. It is shown that the latter case can always replicate the former, but not vice versa. This emphasizes the quantum nature of the information being fed back. Two approaches are used to describe the feedback: quantum trajectories (which apply only for feedback based on measurement) and quantum Langevin equations (which can be used in either case), and the results are shown to be equivalent. The obvious applications for the theory are in quantum optics, where the information is lost by radiation damping and can be retrieved by photodetection. A few examples are discussed, one of which is particularly interesting as it has no classical counterpart.

Abstract:
Although global higher education partnerships can promote greater intercultural understanding, establish unique environments for student and faculty development, and generate opportunities for innovative and entrepreneurial ventures, they can be beset with problems that negate their potential effectiveness. This paper proposes that open systems theory offers a constructive lens for reimagining global higher education partnerships so that they not only benefit internal stakeholders, but also society. It begins with the basic concepts associated with systems theory, with particular attention to the differences between rational and natural systems, as well as open and closed systems. To project how open systems theory might encourage global partnerships to embrace institutional outreach with the environment, the relationship of open systems theory with community engagement is then explored. Finally, the paper shows how boundaries can be either reinforced or traversed through deliberate buffering, bridging, and boundary spanning strategies.

Abstract:
In this paper, we advocate the use of open dynamical systems, i.e. systems sharing input and output variables with their environment, and the dissipativity theory initiated by Jan Willems as models of thermodynamical systems, at the microscopic and macroscopic level alike. We take linear systems as a study case, where we show how to derive a global Lyapunov function to analyse networks of interconnected systems. We define a suitable notion of dynamic non-equilibrium temperature that allows us to derive a discrete Fourier law ruling the exchange of heat between lumped, discrete-space systems, enriched with the Maxwell–Cattaneo correction. We complete these results by a brief recall of the steps that allow complete derivation of the dissipation and fluctuation in macroscopic systems (i.e. at the level of probability distributions) from lossless and deterministic systems.

Abstract:
In this discussion paper we argue that category theory may play a useful role in formulating, and perhaps proving, results in ergodic theory, topogical dynamics and open systems theory (control theory). As examples, we show how to characterize Kolmogorov–Sinai, Shannon entropy and topological entropy as the unique functors to the nonnegative reals satisfying some natural conditions. We also provide a purely categorical proof of the existence of the maximal equicontinuous factor in topological dynamics. We then show how to define open systems (that can interact with their environment), interconnect them, and define control problems for them in a unified way.
