The Entropies
Roumen Tsekov
Entropy is critically examined as a fundamental concept in contemporary science and informatics. Although the typical Shannon entropy provides a proper framework for describing the…
Social Thermodynamics 2.0
Roumen Tsekov
Trailing the modern ideas of sociophysics, a minimalistic thermodynamic model of society is proposed, which consists of three social ingredients: people, economy, and entropy. Empl…
Advanced Thermostats for Molecular Dynamics
Roumen Tsekov
Advanced thermostats for molecular dynamics are proposed on the base of the rigorous Langevin dynamics. Because the latter accounts for the subsystem-bath interactions in details,…
Quantum Entanglement of Free Particles
Roumen Tsekov
The Schrodinger equation is solved for many free particles and their quantum entanglement is studied via correlation analysis. Converting the Schrodinger equation in the Madelung h…
Classical and Quantum Brownian Motion
Roumen Tsekov
In the frames of classical mechanics the generalized Langevin equation is derived for an arbitrary mechanical subsystem coupled to the harmonic bath of a solid. A time-acting tempe…
A Nonlinear Master Equation for Open Quantum Systems
Roumen Tsekov
A nonlinear master equation is derived, reflecting properly the entropy of open quantum systems. In contrast to linear alternatives, its equilibrium solution is exactly the canonic…
