【报告摘要】：In this presentation, I will introduce our recent works in the fields of cavity and waveguide quantum electrodynamics (QED). On the one hand, in the field of cavity QED, we proposed a new type of cavity QED system, which allows us to exponentially enhance the single-atom cooperativity parameter. It overcomes the Q-V trade-off, i.e., Q being directly proportional to V, in the conventional cavity QED systems. On the other hand, in the field of waveguide QED, we investigated thechiral interaction and disorder of qubit array inducedstrongly correlated photons. We found that chiral cavity-waveguide interaction or the disorder in the transition frequencies of qubits can induce photon antibunching, and especially nearly perfect photon blockade events.We also will introduce our recent work regarding the exotic long-range interaction and the associating quantum many-body phases in topological waveguide QED system. Our works is of fundamental interest in expanding the fields of cavity and waveguide QED, and has potential applicationsin the on-chip quantum information science and quantum simulation of strong correlatedmatters.
