AI 中文摘要
探测、理解、预测和控制开放系统中量子相变的实时动力学对现代凝聚态物理、统计物理和量子计算等至关重要。本文认为，弱耦合到有限温度环境的开放系统中的量子临界性需要一个独特的时间重整化群本征值。这一新物理使得能够制定一个通用标度理论，可准确解释此类开放量子系统中的临界性质，包括特定的基布尔 - 祖雷克标度。值得注意的是，除了欧姆浴外，与时间相关量的临界指数会非微扰地改变，无论耦合多弱。还讨论了未来研究的前景。
英文摘要
Probing, understanding, predicting, and controlling the real-time dynamics of quantum phase transitions in open systems are of pivotal importance to modern condensed matter physics, statistical physics, and quantum computing, among others. Here it is argued that a distinct temporal renormalization-group eigenvalue is needed for quantum criticality in open systems weakly coupled to their finite-temperature environment. This new physics enables the formulation of a general scaling theory that can accurately account for the critical properties including the specific Kibble-Zurek scaling in such open quantum systems. Remarkably, the critical exponents of time-related quantities are altered nonperturbatively regardless of how weak the coupling is, except for an Ohmic bath. Perspectives for future study are also discussed.
