Large-scale array of squeezed light and synchronization using atomic vapor

Abstract Quantum light sources such as squeezed light are essential for quantum information science and technologies, but the scalable production of multiple beams of them remains a challenge. Here, we experimentally demonstrate a novel approach to the generation of a large spati...

Unveiling non-Hermitian band structures with non-Bloch supercells

Abstract Real-valued band structures underpin the analysis of periodic Hermitian systems and are well established experimentally. By contrast, non-Hermitian systems feature complex band structures, in which energy and momentum acquire imaginary parts, enabling phenomena that defy...
