The goal of this project is to study the universal properties of many-body quantum systems far from equilibrium and their possible connection to equilibrium critical phenomena and the Kibble-Zurek mechanism. A central objective is to classify the approach to non-thermal attractor solutions and their universal aspects. We consider different far from equilibrium initial conditions, dimensionality, and microscopic interaction strength. In addition, we will develop tools to probe many-body systems through higher-order correlations and repeated quantum limited measurements with the long-term goal to measure the effective quantum field theory descriptions of many-body quantum systems.

该项目的目标是研究远离平衡的多体量子系统的普遍性质及其与平衡临界现象和Kibble-Zurek机制的可能联系。一个中心目标是对非热吸引子解决方案及其通用方面的方法进行分类。我们考虑不同的远离平衡的初始条件，维数，和微观相互作用强度。此外，我们将开发工具，通过高阶相关性和重复的量子有限测量来探测多体系统，其长期目标是测量多体量子系统的有效量子场论描述。
