Project Description:

How information flows in a many-body system is a problem of physical interest. One way to model the information flow is to perturb the many-body system and study the time evolution of the physical observables. This problem of "quantum quenches" has been studied in many papers. In this project, we study this problem using a quantum simulator. We focus on the XXZ model and investigate the time evolution of a two-point function following a quantum quench. We consider two protocols of quantum quench. In the first protocol, we perturb the ground state of the XXZ model in the gapless phase. In the second protocol, we deform the Hamiltonian of the XXZ model by changing the value of the parameter $\Delta$.
