Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

Plexcitonics is a rapidly developing interdisciplinary field that holds immense potential for
the creation of innovative optical technologies and devices. This field focuses on …

The dipole approximation is usually employed to describe light-matter interactions under
ordinary conditions. With the development of artificial atomic systems,'giant atom'physics is …

Abstract Models of light–matter interactions in quantum electrodynamics typically invoke the
dipole approximation,, in which atoms are treated as point-like objects when compared to …

We theoretically study the few-and many-body dynamics of photons in chiral waveguides. In
particular, we examine pulse propagation through an ensemble of N two-level systems …

Engineering light-matter interactions at the quantum level has been central to the pursuit of
quantum optics for decades. Traditionally, this has been done by coupling emitters, typically …

Devices that use quantum advantages for storing energy in the degree of freedom of
quantum systems have drawn attention due to their properties of working as quantum …

In quantum optics, it is common to assume that atoms can be approximated as point-like
compared to the wavelength of the light they interact with. However, recent advances in …

Free-space coupling to subwavelength individual optical elements is a central theme in
quantum optics, as it allows the control over individual quantum systems. Here we show that …

We investigate coherent single-photon transport in a waveguide-QED structure containing
two giant atoms. The unified analytical expressions of the single-photon scattering …
