DOI: 10.1007/s11467-021-1135-0

Abstract: The nonlocal emitter-waveguide coupling, which gives birth to the so called giant atom, represents a new paradigm in the field of quantum optics and waveguide QED. We investigate the single-photon scattering in a one-dimensional waveguide… read more here.

DOI: 10.1088/1367-2630/accd8c

Abstract: We propose a scheme to enhance photon blockades simultaneously in two microwave cavities connected by a giant atom. In the case that only one cavity is weakly driven, we observe that the enhanced photon blockades… read more here.

DOI: 10.1088/1402-4896/ada317

Abstract: We propose an innovative model predicated on giant atom-cavity system, wherein three cavity modes are interconnected via nearest-neighbor photon tunneling, and a giant atom is simultaneously coupled with two single-mode cavities on each side. This… read more here.

DOI: 10.1088/1612-202x/ad6e64

Abstract: We theoretically investigate single-photon scattering and nonreciprocal transmission in a coupled resonator waveguide which is coupled to a driven three-level giant atom via two distant sites. In our system, the local coupling phases are introduced… read more here.

DOI: 10.1103/physreva.104.033710

Abstract: We investigate the single-photon scattering spectra of a giant atom coupled to a one dimensional waveguide via multiple connection points or a continuous coupling region. Using a full quantum mechanical method, we obtain the general… read more here.

DOI: 10.1364/oe.444096

Abstract: In this work, the single photon scattering due to a giant atom coupled with a pair of waveguides is investigated theoretically. Using the real-space Hamiltonian, four scattering amplitudes are obtained, and the single photon routing… read more here.

DOI: 10.1364/oe.560296

Abstract: Exceptional points (EPs), singularities in non-Hermitian systems where eigenvalues and eigenvectors coalesce, have enabled groundbreaking phenomena such as unidirectional invisibility, chiral transmission, and enhanced sensing. However, their sensitivity to perturbations, particularly frequency detuning, poses a… read more here.

DOI: 10.3390/photonics12080827

Abstract: We explore the spontaneous emission dynamics of a giant atom coupled to a photonic Creutz ladder, focusing on how flat-band frustration and synthetic gauge fields shape atom–photon interactions. The Creutz ladder exhibits perfectly flat bands,… read more here.
