The physics of a photonic structure is commonly described in terms of its apparent geometric
dimensionality. On the other hand, with the concept of synthetic dimension, it is in fact …

In the field of quantum simulation of condensed matter phenomena by artificially
engineering the Hamiltonian of an atomic, molecular or optical system, the concept of …

Quantum walks are the quantum mechanical analog of classical random walks and an
extremely powerful tool in quantum simulations, quantum search algorithms, and even for …

Parity-time (PT)-symmetric Hamiltonians have widespread significance in non-Hermitian
physics. APT-symmetric Hamiltonian can exhibit distinct phases with either real or complex …

Topological phases feature robust edge states that are protected against the effects of
defects and disorder. These phases have largely been studied in conservatively coupled …

Disorder and non-Hermiticity dramatically impact the topological and localization properties
of a quantum system, giving rise to intriguing quantum states of matter. The rich interplay of …

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 …

Matter transport is a fundamental process in nature. Understanding and manipulating flow in
a synthetic media often have rich implications for modern device design. Here we …

Symmetries play a major role in identifying topological phases of matter and in establishing
a direct connection between protected edge states and topological bulk invariants via the …

The notion of non-Hermitian optics and photonics rooted in quantum mechanics and
photonic systems has recently attracted considerable attention ushering in tremendous …
