2022 Giant atoms with modulated transition frequency

  title={2022 Giant atoms with modulated transition frequency},
  author={Lei Du and Yan Zhang and 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 giant atom with dynamically modulated transition frequency. It is shown that the retarded feedback effect of the giant-atom system is greatly modified by a dynamical phase arising from the frequency modulation and the retardation effect itself. Interestingly, such a modification can in turn suppress the retarded feedback…

Interaction between giant atoms in a one-dimensional structured environment

Giant atoms—quantum emitters that couple to light at multiple discrete points—are emerging as a new paradigm in quantum optics thanks to their many promising properties, such as decoherence-free



Giant atoms with time-dependent couplings

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 effect cannot be ignored,

Giant Atoms in Synthetic Frequency Dimensions

Giant atoms with nonlocal couplings to real-space waveguides have attracted extensive attention due to their unique interference effects. Here, we propose a feasible scheme for constructing giant

Single-photon frequency conversion via a giant Λ -type atom

We study single-photon scattering at a giant Λ-type atom, where both atomic transitions are coupled with the modes of a single waveguide at two separated points. The giant-atom structure brings

Nonreciprocal frequency conversion with chiral Λ -type atoms

In this paper, we begin with a model of a Λ-type atom whose both transitions are chirally coupled to a waveguide and then extend the model to its giant-atom version. We investigate the single-photon

Designing frequency-dependent relaxation rates and Lamb shifts for a giant artificial atom

In traditional quantum optics, where the interaction between atoms and light at optical frequencies is studied, the atoms can be approximated as pointlike when compared to the wavelength of light. So

Photonic simulation of giant atom decay.

A photonic simulation of non-Markovian giant atom decay, based on light escape dynamics in an optical waveguide nonlocally coupled to a waveguide lattice, is suggested, which can be emulated in this system.

Oscillating bound states for a giant atom

We investigate the relaxation dynamics of a single artificial atom interacting, via multiple coupling points, with a continuum of bosonic modes (photons or phonons) in a one-dimensional waveguide. In

Phase-modulated Autler-Townes splitting in a giant-atom system within waveguide QED

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

Giant acoustic atom: A single quantum system with a deterministic time delay

We investigate the quantum dynamics of a single transmon qubit coupled to surface acoustic waves (SAWs) via two distant connection points. Since the acoustic speed is five orders of magnitude slower

Beyond spontaneous emission: Giant atom bounded in the continuum

The quantum coupling of individual superconducting qubits to microwave photons leads to remarkable experimental opportunities. Here we consider the phononic case where the qubit is coupled to an
