Figure 1. Schematic diagram of the finite-time Carnot-like cycle for a two-level atomic heat engine. The horizontal axis and the vertical axis represent respectively the energy spacing ω and excited state population pe of the two-level atom. The red (right) and blue (left) solid curves represent the high-temperature and low-temperature finite-time quasi-isothermal processes, respectively. The black (horizontal) solid lines represent the adiabatic processes.
