用于粒子生成的淬火和晶格模拟器
Quenches and lattice simulators for particle creation
摘要：
在本文中，我们提出了一个框架来模拟凝聚态系统中的热粒子产生。我们所描述的过程可以通过模型中参数的量子猝灭来实现。为了支持这一说法，我们研究了二次费米子系统在一维和二维的分析和数值技术。特别是，我们能够证明，一类与Unruh-德维特探测器相关的观测值与这种类型的设置非常相关，并且表现出近似热化。
英文摘要：
In this paper we propose a framework for simulating thermal particle production in condensed matter systems. The procedure we describe can be realized by means of a quantum quench of a parameter in the model. In order to support this claim, we study quadratic fermionic systems in one and two dimensions by means of analytical and numerical techniques. In particular, we are able to show that a class of observables associated to Unruh--de Witt detectors are very relevant for this type of setup and that exhibit approximate thermalization.
