Apparent violations of the second law in the quantum-classical dynamics of interacting levitated nanoparticles
arXiv:2501.12305 · doi:10.1103/5s83-qzzk
Abstract
Random exchanges of energy arise naturally in stochastic systems. As a consequence, apparent violations of the second law of thermodynamics can occur, as it holds true on average. Here we investigate the occurrence of these apparent violations -- termed free lunches -- in a quantum-classical system comprised of levitated nanoparticles exchanging energy via the Coulomb interaction. We consider different initial states for the quantum system, and how these exert work and fluctuations upon the classical particle affecting the probability of free lunches. With that, we initiate the study of hybrid quantum-classical systems through the lens of stochastic thermodynamics.
