论文摘要
我们探讨了量子机械挤压对两个挤压谐波储层和一个两个级别系统之间骨传输的非平衡波动的影响。采用了基于量子主方程的标准完整计数统计技术。我们在两个挤压储层的相等温度设置下得出非零热力学亲和力。奇数累积物显示出与在对称条件下挤压无关的,而均匀的累积物则非线性地取决于挤压参数。奇数甚至累积在两个不同但独特的值分析的值下饱和。此外,与未进行的情况相比,挤压总是会增加均匀累积物的大小。我们还以挤压依赖的热力学亲和力恢复了稳态波动定理,并证明了稳态热力学不确定性关系的鲁棒性。
We explore the effects of quantum mechanical squeezing on the nonequilibrium fluctuations of bosonic transport between two squeezed harmonic reservoirs and a two level system. A standard full counting statistics technique based on a quantum master equation is employed. We derive a nonzero thermodynamic affinity under equal temperature setting of the two squeezed reservoirs. The odd cumulants are shown to be independent of squeezing under symmetric conditions, whereas the even cumulants depend nonlinearly on the squeezing parameters. The odd and even cumulants saturate at two different but unique values which are identified analytically. Further, squeezing always increases the magnitude of the even cumulants in comparison to the unsqueezed case. We also recover a steady state fluctuation theorem with squeezing dependent thermodynamic affinity and demonstrate the robustness of a steadystate thermodynamic uncertainty relationship.
