Over the past decade, topology has emerged as a major branch in broad areas of physics,
from atomic lattices to condensed matter. In particular, topology has received significant …

Disorder, which qualitatively describes some measure of irregularities in spatial patterns, is
ubiquitous in many-body systems, equilibrium and non-equilibrium states of matter, network …

Topological photonics is a new and rapidly growing field that deals with topological phases
and topological insulators for light. Recently, the scope of these systems was expanded …

The hallmark of topological insulators (TIs) is the scatter-free propagation of waves in
topologically protected edge channels. This transport is strictly chiral on the outer edge of …

Non-Hermitian skin effect (NHSE) has led to interesting physics and sophisticated
applications beyond the conventional framework. However, NHSE studies have been limited …

The concept of synthetic dimensions in photonics has attracted rapidly growing interest in
the past few years. Among a variety of photonic systems, the ring resonator system under …

Waveguide lattices offer a compact and stable platform for a range of applications, including
quantum walks, condensed matter system simulation, and classical and quantum …

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 …

Spontaneous emission of an excited atom in a featureless continuum of electromagnetic
modes is a fundamental process in quantum electrodynamics associated with an …

Edge states in topological phase transitions have been observed in various platforms. To
date, verification of the edge states and the associated topological invariant are mostly …
