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…
Universal Foundations of Thermodynamics: Entropy and Energy Beyond Equilibrium and Without Extensivity
Gian Paolo Beretta
Thermodynamics is commonly presented as a theory of macroscopic systems in stable equilibrium, built upon assumptions of extensivity and scaling with system size. In this paper, we…
No-Signaling in Steepest Entropy Ascent: A Nonlinear Non-local Non-equilibrium Quantum Dynamics of Composite Systems
Rohit Kishan Ray, Gian Paolo Beretta
The Lindbladian formalism models open quantum systems using a 'bottom-up' approach, deriving linear dynamics from system-environment interactions. We present a 'top-down' approach…
Method for Generating Randomly Perturbed Density Operators Subject to Different Sets of Constraints
J. A. Montanez-Barrera, R. T. Holladay, G. P. Beretta +1
This paper presents a general method for producing randomly perturbed density operators subject to different sets of constraints. The perturbed density operators are a specified "d…
New definitions of thermodynamic temperature and entropy not based on the concepts of heat and thermal reservoir
Gian Paolo Beretta, Enzo Zanchini
From a new rigorous formulation of the general axiomatic foundations of thermodynamics we derive an operational definition of entropy that responds to the emergent need in many tec…
Time-Energy and Time-Entropy Uncertainty Relations in Nonequilibrium Quantum Thermodynamics under Steepest-Entropy-Ascent Nonlinear Master Equations
Gian Paolo Beretta
In the domain of nondissipative unitary Hamiltonian dynamics, the well-known Mandelstam-Tamm-Messiah time-energy uncertainty relation provides a general lower…
