报告摘要/Abstract In this talk, I will discuss a novel method to probe many-body correlation using dissipation as a tool. This is termed as non-hermitian linear response theory. I will discuss how this method applies to explaining cold atom experiments in optical lattices, and I will report recent further experimental confirmation in one-dimensional atomic gases. This formula can also help us understand the fragility of quantized conductance in quantum spin Hall effect in solid state materials. I will further discuss the topology of open quantum states described by the modular Hamiltonian and the dissipation dynamics-driven topological phase transition.
