标题： Non-adiabatic linear response in open quantum systems

摘要： 绝热定理和非绝热修正在现代量子技术中得到了广泛应用。最近，非绝热线性响应理论被开发出来，以探测封闭系统中的多体关联。在本工作中，我们将非绝热线性响应理论推广到开放量子多体系统。我们发现，从稳态的线性偏差是无记忆的，类似于封闭系统。在调节哈密顿量时，可观测量的线性响应仍然与滞后格林函数的导数相关。然而，当调节耗散时，相应的系数由稳态中的一个新的高阶关联函数决定。我们的工作给出了一个简洁的结果，并将调节动力学的工具推广到研究开放量子系统中的多体关联。 显示英文摘要

摘要： Adiabatic theorem and non-adiabatic corrections have been widely applied in modern quantum technology. Recently, non-adiabatic linear response theory has been developed to probe the many-body correlations in closed systems. In this work, we generalize the non-adiabatic linear response theory to open quantum many-body systems. We find that the linear deviation from steady states is memory-less, similar to the closed system. The linear response of observables while ramping the Hamiltonian is still related to the derivative of the retarded Green's function. However, as one ramps the dissipation, the corresponding coefficient is determined by a new high-order correlation function in the steady state. Our work gives a neat result and generalizes the tool of ramping dynamics to study the many-body correlations in open quantum systems.
