Title: | Thermodynamics of a stochastic twin elevator | Authors: | Kumar, Niraj VAN DEN BROECK, Christian Esposito, Massimiliano Lindenberg, Katja |
Issue Date: | 2011 | Publisher: | AMER PHYSICAL SOC | Source: | PHYSICAL REVIEW E, 84 (5) | Abstract: | We study the nonequilibrium thermodynamics of a single particle with two available energy levels, in contact with a classical (Maxwell-Boltzmann) or quantum (Bose-Einstein) heat bath. The particle can undergo transitions between the levels via thermal activation or deactivation. The energy levels are alternately raised at a given rate regardless of occupation by the particle, maintaining a fixed energy gap equal to e between them. We explicitly calculate the work, heat, and entropy production rates. The efficiency in both the classical and the quantum case goes to a limit between 100 and 50% that depends on the relative rates of particle transitions and level elevation. In the classical problem we explicitly find the large deviation functions for heat, work, and internal energy. | Notes: | [Kumar, Niraj; Lindenberg, Katja] Univ Calif San Diego, Dept Chem & Biochem, La Jolla, CA 92093 USA.
