摘要：

The quantum thermodynamics of a fixed or oscillating two-level atom interacting with a controlled classical external field is investigated in the framework of the two-point measurement scheme. For a fixed two-level atom, by ignoring the fast oscillating terms, the rotating wave approximation is applied, and also by taking into account the fast oscillating terms, a numerical approach is used. For the oscillating two-level atom, calculations are exact and we have closed-form expressions for the results. The population dynamics, decoherency function, characteristic function, work distribution, and Helmholtz free energy are calculated and discussed. The Jarzynski theorem's consistency is verified.
