Decay dynamics of a giant atom in a structured bath with broken time-reversal symmetry
Lei Du, Yao-Tong Chen, Yan Zhang +2
We study in this paper the decay dynamics of a two-level giant atom, which is coupled to a quasi-one-dimensional sawtooth lattice exposed to uniform synthetic magnetic fluxes. In t…
Light transfer transitions beyond higher-order exceptional points in parity-time and anti-parity-time symmetric waveguide arrays
Chuanxun Du, Gang Wang, Yan Zhang +1
We propose two non-Hermitian arrays consisting of waveguides and exhibiting parity-time () or anti- symmetry for investigating light transfer d…
Nonreciprocal and chiral single-photon scattering for giant atoms
Yao-Tong Chen, Lei Du, Lingzhen Guo +4
Quantum optics with giant atoms has provided a new paradigm to study photon scatterings. In this work, we investigate the nontrivial single-photon scattering properties of giant at…
Giant atoms with time-dependent couplings
Lei Du, Yao-Tong Chen, Yan Zhang +1
We study the decay dynamics of a two-level giant atom that is coupled to a waveguide with time-dependent coupling strengths. In the non-Markovian regime where the retardation effec…
