Time-varying media have recently emerged as a new paradigm for wave manipulation, due
to the synergy between the discovery of highly nonlinear materials, such as epsilon-near …

Time-varying systems open intriguing opportunities to explore novel approaches in the
design of efficient electromagnetic devices. While such explorations date back to more than …

Entanglement and topology portray nature at the fundamental level but differently. Entangled
states of particles are intrinsically sensitive to the environment, whereas the topological …

Measuring topological invariants is an essential task in characterizing topological phases of
matter. They are usually obtained from the number of edge states due to the bulk-edge …

The moiré lattice has recently attracted broad interest in both solid-state physics and
photonics where exotic phenomena in manipulating the quantum states are explored. In this …

Temporal modulation recently draws great attentions in wave manipulations, with which one
can introduce the concept of temporal multilayer structure, a temporal counterpart of spatially …

Photonic simulators using synthetic frequency dimensions have enabled flexible
experimental analogues of condensed-matter systems. However, so far, such photonic …

The concept of synthetic dimension has recently emerged as a versatile way to overcome
limitations in the number of effectively available dimensions by leveraging non‐spatial …

Non-Abelian gauge fields give rise to nontrivial topological physics. Here we develop a
scheme to create an arbitrary SU (2) lattice gauge field for photons in the synthetic frequency …

It is of fundamental interest in controlling the light–matter interaction for a long time in the
field of quantum information processing. Here, we explore a model by coupling a giant atom …
