随机场伊辛模型中的动态量子相变

在过去的几年里，人们指出，时间演化量子系统的某些可观测量可能在某些时刻具有奇点，模仿物理系统在经历相变时的奇点。这些被称为动态相变。它们被证明存在于某些可积（精确可解）的量子系统中，并在实验中发现了与这些可解模型相关（但不完全相同）的一些设置。然而，这种奇点的“普适类”还没有令人信服地建立起来。我们认为，随机场伊辛模型的功能奇点的时间可能存在于更广泛的各种量子系统，特别是在那些许多机构本地化，并详细描述这些奇点解析。
Over the last few years it was pointed out that certain observables of time-evolving quantum systems may have singularities at certain moments in time, mimicking the singularities physical systems have when undergoing phase transitions. These were given the name of dynamical phase transitions. They were shown to exist in certain integrable (exactly solvable) quantum systems, and were seen experimentally in some setups related (but not identical) to these solvable models. The "universality classes" of such singularities were not yet convincingly established, however. We argue that random field Ising models feature singularities in time which may potentially be present in a wider variety of quantum systems, in particular in those which are many body localized, and describe these singularities in detail analytically.
