Abstract
Abstract An oscillating bound state is a phenomenon where excitations mediated by the continuum modes oscillate persistently. Although it is generated by the superposition of two bound states in the continuum (BICs), such phenomenon is said to be unique to giant atoms. The phenomenon of an oscillating bound state with an alternative waveguide QED system is presented, which is a one dimensional (1D) semi‐infinite waveguide coupled to a point‐like quantum emitter. This point‐like quantum emitter is ‐type quantum system with one transition driven by a classical field.
