报告摘要：

Traditional quantum electrodynamics usually models single atoms as points based on the electric-dipole approximation. This tenet nowadays can break up in so-called “giant atom” (GA) systems. GAs are (artificial) quantum emitters that are coupled to the field at multiple separate points (thus featuring non-local atom-field interactions). As the separation distances between different coupling points can be comparable to the wavelength of the field, a GA behaves as a sort of quantum interferometer, leading to a series of unconventional quantum optical phenomena, such as frequency-dependent Lamb shifts and relaxation rates, in-band decoherence-free interactions, exotic photon-atom bound states, non-Markovian dynamics, and advanced photon scatterings, to name a few. In this talk, I will first give a brief overview of GAs and then introduce some recent works of us based on the combination of GAs and dynamical modulations.
