论文摘要
我们研究了熵产生速率和相对功率波动之间的权衡热力学不确定性关系（TUR），对于非排定三级和退化的四级Maser热发动机之间的权衡。在非重型情况下，我们考虑了两种三级MASER热发动机的略有不同的配置，并将其对比其违反标准TUR的程度。在高温限制中，两种配置始终违反标准TUR关系。我们还发现了在物质场耦合常数和系统浴耦合常数的同时重新缩放下TUR的不变性。对于退化的四级发动机，我们研究了噪声引起的连贯性对TUR的影响。我们表明，根据操作的参数状态，噪声引起的连贯性可以抑制或增强相对功率波动。
We investigate the thermodynamic uncertainty relation (TUR), \textit{i.e.} a trade-off between entropy production rate and relative power fluctuations, for nondegenerate three-level and degenerate four-level maser heat engines. In the nondegenerate case, we consider two slightly different configurations of three-level maser heat engine and contrast their degree of violation of standard TUR. In the high-temperature limit, standard TUR relation is always violated for both configurations. We also uncover an invariance of TUR under simultaneous rescaling of the matter-field coupling constant and system-bath coupling constants. For the degenerate four level engine, we study the effects of noise-induced coherence on TUR. We show that depending on the parametric regime of operation, noise-induced coherence can either suppress or enhance the relative power fluctuations.
