Topologically protected subradiant cavity polaritons through linewidth narrowing enabled by dissipationless edge states
Yuwei Lu, Jingfeng Liu, Haoxiang Jiang +1
Cavity polaritons derived from the strong light-matter interaction at the quantum level provide a basis for efficient manipulation of quantum states via cavity field. Polaritons wi…
Anomalous spontaneous emission dynamics at chiral exceptional points
Yuwei Lu, Yanhui Zhao, Runhua Li +1
An open quantum system operated at the spectral singularities where dimensionality reduces, known as exceptional points (EPs), demonstrates distinguishing behavior from the Hermiti…
Fano effect induced giant and robust enhancement of photon correlations in cavity QED systems
Yu-Wei Lu, Jing-Feng Liu, Runhua Li +2
Fano effect arising from interference between two dissipation channels to the radiation continuum enables to tune the photon statistics. Understanding the role of Fano effect and e…
Single-photon blockade in quasichiral atom-photon interaction: Simultaneous high purity and high efficiency
Yu-Wei Lu, Jing-Feng Liu, Runhua Li +3
We investigate the single-photon blockade (1PB) in the quasichiral regime of atom-photon interaction that mediates via dissipative environment, where the effective atom-photon inte…
Strong magneto-optical response enabled by quantum two level systems
Lei Ying, Ming Zhou, Xiaoguang Luo +2
The magneto-optical effect breaks time-reversal symmetry, a unique property that makes it indispensable in nonreciprocal optics and topological photonics. Unfortunately, all natura…
Atomic metasurfaces for manipulation of single photons
Ming Zhou, Jingfeng Liu, Mikhail Kats +1
Metasurfaces are an emerging platform for manipulating light on a two-dimensional plane. Existing metasurfaces comprise arrays of optical resonators such as plasmonic antennas or h…
Quantum scattering theory of Fock states in high-dimensional spaces
Jingfeng Liu, Ming Zhou, Zongfu Yu
A quantum scattering theory is developed for Fock states scattered by two-level systems in the free space. Compared to existing scattering theories that treat incident light semi-c…
Discrete solitons and vortices on two-dimensional lattices of -symmetric couplers
Zhaopin Chen, Jingfeng Liu, Shenhe Fu +2
We introduce a 2D network built of -symmetric dimers with on-site cubic nonlinearity, the gain and loss elements of the dimers being linked by parallel square-shaped…
Lattice solitons with quadrupolar intersite interactions
Yongyao Li, Jingfeng Liu, Wei Pang +1
We study two-dimensional (2D) solitons in the mean-field models of ultracold gases with long-range quadrupole-quadrupole interaction (QQI) between particles. The condensate is load…
Matter-wave solitons supported by field-induced dipole-dipole repulsion with a spatially modulated strength
Yongyao Li, Jingfeng Liu, Wei Pang +1
We demonstrate the existence of one and two-dimensional bright solitons in the Bose-Einstein condensate with repulsive dipole-dipole interactions induced by a combination of dc and…
Symmetry breaking in dipolar matter-wave solitons in dual-core couplers
Yongyao Li, Jingfeng Liu, Wei Pang +1
We study effects of the spontaneous symmetry-breaking (SSB) in solitons built of the dipolar Bose-Einstein condensate (BEC), trapped in a dual-core system with the dipole-dipole in…
Ab-initio Mapping of Projected Local Density of States in Arbitrary Nanostructures: Application to Photonic Crystal Slabs and Cavities
Gengyan Chen, Yi-Cong Yu, Xiao-Lu Zhuo +5
Based upon projected local density of states (PLDOS) for photons, we develop a local coupling theory to simultaneously treat the weak and strong interaction between a quantum emitt…
