Lithium niobate (LN), an outstanding and versatile material, has influenced our daily life for
decades—from enabling high-speed optical communications that form the backbone of the …

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 …

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 …

Abstract The era of Big Data requires nanophotonic chips to have large information
processing capacity. Multiple frequency on-chip nanophotonic devices are highly desirable …

Topological phases enable protected transport along the edges of materials, offering
immunity against scattering from disorder and imperfections. These phases have been …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

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

Giant atoms that interact with real-space waveguides at multiple spatial points have attracted
extensive attention due to their unique interference effects. Here we propose a feasible …

When a physical system is subjected to a strong external multifrequency drive, its dynamics
can be conveniently represented in the multidimensional Floquet lattice. The number of …

We study a 1D chain of noninteracting bosonic cavities which are subject to nearest-
neighbor parametric driving, thus realizing a bosonic Hamiltonian whose form is reminiscent …
