Overview of project B03
Quench Dynamics in Interacting Quantum Many-Body Systems
This project aims to study the temporal evolution after a quantum quench in several experimentally relevent scenarios by means of suitable model Hamiltonians and comparing it with other excitation mechanisms. The goal is the theoretical understanding of the dependence of this temporal evolution on the intrinsic dynamics of the system, the initial conditions (e.g., temperature), and the specific mechanism of excitation or quenching.
