Waveguide quantum electrodynamics offers a wide range of possibilities to effectively
engineer interactions between artificial atoms via a one-dimensional open waveguide …

We reveal the emergence of quantum Hall phases, topological edge states, spectral Landau
levels, and Hofstadter butterfly spectra in the two-particle Hilbert space of an array of …

Topological phases play a crucial role in the fundamental physics of light-matter interaction
and emerging applications of quantum technologies. However, the topological band theory …

Beyond the well-known topological band theory for single-particle systems, it is a great
challenge to characterize the topological nature of interacting multiparticle quantum …

We study the topological properties of hardcore bosons on a two-leg ladder consisting of two
Su-Schrieffer-Heeger chains that are coupled via hop** and interaction. We chart out the …

We investigate theoretically the Bose–Hubbard version of the celebrated Su-Schrieffer-
Heeger topological model, which essentially describes a one-dimensional dimerized array …

The rapid progress in quantum information processing leads to a rising demand for devices
to control the propagation of electromagnetic wave pulses and to ultimately realize universal …

Particle-particle interaction provides a new degree of freedom to induce novel topological
phenomena. Here, we propose to use spatiotemporal modulation of interaction to realize …

We study the emergence of two types of two-photon bounds states in waveguides of any
chirality. Specifically, we present a systematic way of analytically determining the …

Cavity polaritons derived from strong light–matter interaction provide a basis for efficient
manipulation of quantum states via cavity field. Polaritons with narrow linewidth and long …
