Quantum Thermodynamics with Degenerate Eigenstate Coherences
We establish quantum thermodynamics for open quantum systems weakly coupled to their reservoirs when the system exhibits degeneracies. The first and second law of thermodynamics are derived, as well as a finite-time fluctuation theorem for mechanical ...

Discretization of continuum physics – a comparison of numerical methods from a physical point of view; pp. 145–154 [PDF]
For numerical calculations in continuum physics partial differential equations and the space-time are discretized. This can be done in different ways. Common approaches are finite difference methods and finite element methods, more rarely finite volume ...

Virial statistical description of non-extensive hierarchical systems [PDF]
In a first part the scope of classical thermodynamics and statistical mechanics is discussed in the broader context of formal dynamical systems, including computer programmes. In this context classical thermodynamics appears as a particular theory suited

A Dynamic Approach to the Thermodynamics of Superdiffusion [PDF]
We address the problem of relating thermodynamics to mechanics in the case of microscopic dynamics without a finite time scale. The solution is obtained by expressing the Tsallis entropic index q as a function of the Levy index alpha, and using dynamical

Thermodynamics and fluctuations in finite-time quantum heat engines under reservoir squeezing
We investigate the thermodynamics and fluctuations of a finite-time quantum Otto engine alter- natively driven by a hot-squeezed and a cold thermal reservoir.

Numerical tests of the electroweak phase transition and thermodynamics of the electroweak plasma [PDF]
The finite temperature phase transition in the SU(2) Higgs model at a Higgs boson mass $M_H \simeq 34$ GeV is studied in numerical simulations on four-dimensional lattices with time-like extensions up to $L_t=5$.

Finite-time Landauer principle beyond weak coupling [PDF]
Landauer's principle gives a fundamental limit to the thermodynamic cost of erasing information. Its saturation requires a reversible isothermal process, and hence infinite time.
