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 atoms” (GAs): GAs are (artificial) quantum emitters coupled to the field at multiple separate points (featuring non-local atom-field interaction). As the separation distances between different coupling points can be comparable with the field’s wavelength, a GA behaves as a sort of tiny quantum interferometer, leading to a series of unconventional quantum optical phenomena such as frequency-dependent Lamb shifts and decay rates, 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 we’ve done on this subject.
