Open quantum many-body systems: -when interactions meet dissipations

Seminar

Understanding quantum systems embedded into environment is of particular theoretical and practical importance. The situation becomes particularly interesting and complex when the system itself is already an interacting many-body system, which provides novel perspectives to quantum many-body physics. In this talk, I will present two examples to show how the conspiracy of dissipation and interaction can significantly change the behaviors of the quantum systems and give rise to novel phenomena, including the algebraic decoherence behavior and a dissipation-induced many-body localization. Our numerical methods can be applied to realistic open quantum many-body systems like the trapped ions, or quantum information systems based on solid state devices.
