热力学第二和第三定律可以用来建立一个基本的界限，最大可能的冷却速度接近绝对零度的温度。在为实现超低温的分子制冷机的行为建模时，只有量子力学模型才是可接受的，而不是经典物理模型。作为一个简单的模型，我们分析了一个三能级量子制冷机，特别是它的不可逆的热力学性能接近绝对零度。
The second and third laws of thermodynamics can be used to establish a fundamental bound for the maximum possible cooling rate in approaching the absolute zero of temperature. In modeling the behavior of the molecular refrigerators geared toward attaining ultralow temperatures, only quantum mechanical, as opposed to classical physics, models can be admissible. As a simple model, we analyze a three-level quantum refrigerator, and in particular its irreversible thermodynamic performance as absolute zero is approached.
