We investigate the dynamical evolution of a parity-time (PT) symmetric extension of the
Aubry-André (AA) model, which exhibits the coincidence of a localization-delocalization …

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 …

We study the critical behavior of Anderson localized modes near intersecting flat and
dispersive bands in the quasi-one-dimensional diamond ladder with weak diagonal disorder …

Quantum localization in 1D non-Hermitian systems, especially the search for exact single-
particle mobility edges, has attracted considerable interest recently. While much progress …

We propose and analyze the design of a programmable photonic integrated circuit for high-
fidelity quantum computation and simulation. We demonstrate that the reconfigurability of …

Transport phenomena on a quantum scale appear in a variety of systems, ranging from
photosynthetic complexes to engineered quantum devices. It has been predicted that the …

We investigate a class of optical mesh periodic structures that are discretized in both the
transverse and longitudinal directions. These networks are composed of waveguide arrays …

Light transmission measurements and frequency-delay reflectometry maps for GaAs
photonic crystal membranes are presented and analyzed, showing the transition from …

Our society's appetite for ultra-high bandwidth communication networks and high-power
optical sources, together with recent breakthroughs in mode multiplexing/demultiplexing …

Escaping from a complex maze, by exploring different paths with several decision-making
branches in order to reach the exit, has always been a very challenging and fascinating task …
