Oscillating bound states for a giant atom

We investigate the relaxation dynamics of a single artificial atom interacting, via 6561416 multiple coupling points, with a continuum of bosonic modes (photons or phonons) in a one-dimensional waveguide.In the non-Markovian regime, where the traveling time of a photon or phonon between the coupling points is sufficiently large compared to the inverse of the bare relaxation rate of the atom, we find that a boson can be trapped and form a stable bound state.As a key discovery, we further find that a persistently oscillating bound state can appear inside the continuous spectrum of the waveguide if the number of coupling points is more than two since such a setup enables multiple bound modes vegemite pop art to coexist.This opens up prospects for storing and manipulating quantum information in larger Hilbert spaces than available in previously known bound states.
