Evolution of Hypoequilibrium States in Steepest Entropy Ascent Models for Nonequilibrium Quantum Thermodynamics
Gian Paolo Beretta, Rohit Kishan Ray, Michael R. von Spakovsky
A formal development of the hypoequilibrium (HE) state concept within the Steepest-Entropy-Ascent Quantum Thermodynamics (SEAQT) framework is presented, emphasizing its rigorous ma…
Local perception operators and classicality: new tools for old tests
Rohit Kishan Ray
Quantum nonlocality is often judged by violations of Bell-type inequalities for a given state. The computation of such violations is a global task, requiring evaluation of global c…
Finite-Dimensional Quantum Systems under the Fourth Law of Thermodynamics
Rohit Kishan Ray
The Steepest Entropy Ascent (SEA) ansatz, recently recognized as the fourth law of thermodynamics, governs the irreversible evolution of a system from a non-equilibrium state towar…
Work and entropy of mixing in isolated quantum systems
Budhaditya Bhattacharjee, Rohit Kishan Ray, Dominik Šafránek
The mixing of two different gases is one of the most common natural phenomena, with applications ranging from CO capture to water purification. Traditionally, mixing is analyze…
