Two-Photon Bound States in the Continuum: A No-Go Theorem and Long-Lived Quasi-Bound States

Yue Chang

Two-photon bound states in the continuum provide a stringent setting in which quantum interference must suppress radiative decay despite photon--photon interactions. Here, we prove…

Coherent Control of an Embedded Bound State Without a Spectral Gap

Yue Chang

Bound states in the continuum (BICs) can confine photonic excitations in open systems without conventional cavities or band gaps, making them natural candidates for long-lived quan…

Continuously tunable single-photon level nonlinearity with Rydberg state wave-function engineering

Biao Xu, Gen-Sheng Ye, Yue Chang +2

Extending optical nonlinearity into the extremely weak light regime is at the heart of quantum optics, since it enables the efficient generation of photonic entanglement and implem…

Quantum Beam Splitter as a Quantum Coherence Controller

Li-Ping Yang, Yue Chang

We propose a quantum beam splitter (QBS) with tunable reflection and transmission coefficients. More importantly, our device based on a Hermitian parity-time () symme…

Non-Markovian Multiphoton Chiral Dynamics with Giant Systems

Yue Chang

Chiral interactions enable directional control of quantum light, providing new routes for nonreciprocal photon dynamics. While previous studies focused on single photon regimes, th…

Spin relaxation in inhomogeneous magnetic fields with depolarizing boundaries

Yue Chang, Shuangai Wan, Shichao Dong +1

Field-inhomogeneity-induced relaxation of atomic spins confined in vapor cells with depolarizing walls is studied. In contrast to nuclear spins, such as noble-gas spins, which expe…
