Defining work and heat in quantum systems: Laser light coherence offers a consistent approach
Researchers at the University of Basel have developed a new approach to applying thermodynamics to microscopic quantum systems.
Thermodynamics as a research area investigates the fundamental laws governing energy, entropy, and the macroscopic behavior of physical systems at or near equilibrium, and their extensions to nonequilibrium processes. It encompasses the formulation and application of the four laws of thermodynamics, characterization of state functions, phase behavior, and thermodynamic potentials, and rigorous derivation of efficiency limits for engines, refrigerators, and energy conversion devices. Contemporary research integrates classical, statistical, and quantum thermodynamics to study emergent phenomena, irreversible processes, fluctuation theorems, and information–thermodynamics connections in complex, soft-matter, biological, and nanoscale systems.
