Abstract: We find the phase-controlled bound state out of the continuum~(BOC) and bound state in the continuum~(BIC) in an artificial giant atom dressed one-dimensional photonic waveguide where the giant atom couples to the waveguide via two distant sites. We obtain the existence condition of the BOC as well as the frequency and the photonic distribution in the BIC. More interestingly, we predict the quantum beats in the atomic and photonic dynamical evolution, which is induced by the oscillation between the BIC and the BOCs. These findings provide an approach to manipulate the waveguide system via the bound states.

We investigate the single photon scattering and bound states in a coupled resonator waveguide (CRW) which couples to a topological giant atom (TGA) via two distant sites. By modulating the topological phase of the TGA, the incident photon in the CRW can be completely reflected or transmitted.

Bound state of distant photons in waveguide quantum electrodynamics [137.6408511310322]
Quantum correlations between distant particles remain enigmatic since the birth of quantum mechanics. We predict a novel kind of bound quantum state in the simplest one-dimensional setup of two interacting particles in a box. Such states could be realized in the waveguide quantum electrodynamics platform.

Oscillating bound states in non-Markovian photonic lattices [0.0]
We perform exact calculations for the oscillating BICs in a 1D photonic lattice coupled to "giant atom" at multiple points. We show that the bound states outside the energy band are detrimental to the oscillating BIC phenomenon. Our work can be experimentally implemented on current photonic waveguide array platforms.

Retardation effect and dark state in a waveguide QED setup with rectangle cross section [3.606070542317997]
We study the dynamics of a two-atom system which couples to a quasi-one dimensional waveguide with rectangle cross section. We observe a retardation effect, which is broken by moving one of the atoms to be off-centered. To preserve the complete dissipation of the system via dark state mechanism, we propose a scheme where the connection of the atoms are perpendicular to the axis of the waveguide.

Photon-emitter dressed states in a closed waveguide [0.0]
We study a system made up of one or two two-level quantum emitters, coupled to a single transverse mode of a closed waveguide. We unearth finite-size effects in the field-emitter interactions and identify a family of dressed states, that represent the forerunners of bound states in the continuum in the limit of an infinite waveguide.

Waveguide quantum optomechanics: parity-time phase transitions in ultrastrong coupling regime [125.99533416395765]
We show that the simplest set-up of two qubits, harmonically trapped over an optical waveguide, enables the ultrastrong coupling regime of the quantum optomechanical interaction. The combination of the inherent open nature of the system and the strong optomechanical coupling leads to emerging parity-time (PT) symmetry. The $mathcalPT$ phase transition drives long-living subradiant states, observable in the state-of-the-art waveguide QED setups.
