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…
Enhanced sensing of optomechanically induced nonlinearity by linewidth suppression and optical bistability in cavity-waveguide systems
Chun-Wang Liu, Ye Liu, Lei Du +3
We study enhanced sensing of optomechanically induced nonlinearity (OMIN) in a cavity-waveguide coupled system. The Hamiltonian of the system is anti-PT symmetric with the two invo…
Complex decoherence-free interactions between giant atoms
Lei Du, Lingzhen Guo, Yong Li
Giant atoms provide a promising platform for engineering decoherence-free interactions which is a major task in modern quantum technologies. Here we study systematically how to imp…
A giant atom with modulated transition frequency
Lei Du, Yan Zhang, Yong Li
Giant atoms are known for the frequency-dependent spontaneous emission and associated interference effects. In this paper, we study the spontaneous emission dynamics of a two-level…
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…
