Out of equilibrium systems are gaining increasing attention in the physics community due to their novel properties compared to their static
counterpart. In particular, quantum quench is an established method to probe various aspects of out of equilibrium physics, both theoretically and experimentally. In this talk, I will present how we apply this method to probe defect production across continuous phase transitions in topological and non-Hermitian systems. Our study reveals a modified defect scaling in the presence of exotic topological state, and non-zero defect density in a non-Hermitian system in the adiabatic limit.
