Dynamics of quantum many-body systems in the absence of spatial reflection symmetry

Project description

Study of constraints and symmetries affecting P-symmetric models

Researchers in the field of condensed matter physics have been trying to understand the dynamical response of many-body quantum-mechanical systems to external perturbations, as this question has become a key one that could greatly advance efforts in this and related fields. Despite promising observations over the past decade, such as the role of symmetries in the universal aspects of a system’s dynamical properties, success has been limited. Supported by the Marie Skłodowska-Curie Actions programme, the PSymQDyn project will investigate the effects of spatial translation symmetry. The project will build on a previous applicant’s research by thoroughly and systematically studying the effects and interplay of symmetries and constraints on dynamics in P-symmetric models.

Objective

Understanding the dynamical response of many-body quantum mechanical systems to external perturbations is one of the central questions in condensed matter physics. Over the past decade, it has been observed that symmetries can play an important role in the universal aspects of a system's dynamical properties. In this direction, a question that has not received much attention, and thus remains to be answered, is about the effects of spatial translation symmetry. Our recent results have shown that such systems can show ballistic dynamics, even in the absence of integrability. Therefore, the goal of this proposal is to perform a more systematic study of the effects of P-symmetry breaking in one-dimensional quantum many-body systems, and the interplay between P-symmetry and other symmetries and constraints, that are known to affect dynamics in P-symmetric models.
