Nonreciprocal optical solitons in a spinning Kerr resonator
Baijun Li, Şahin. K. Özdemir, Xun-Wei Xu +3
We propose a spinning nonlinear resonator as an experimentally accessible platform to achieve nonreciprocal control of optical solitons. Nonreciprocity here results from the relati…
General corner states in 2D SSH model with intracelluar next-nearest-neighbour hopping
Xun-Wei Xu, Yu-Zeng Li, Zheng-Fang Liu +1
We investigate corner states in a photonic two-dimensional (2D) Su-Schrieffer-Heeger (SSH) model on a square lattice with zero gauge flux. By considering intracelluar next-nearest-…
Vortex-Meissner phase transition induced by two-tone-drive-engineered artificial gauge potential in the fermionic ladder constructed by superconducting qubit circuits
Yan-Jun Zhao, Xun-Wei Xu, Hui Wang +2
We propose to periodically modulate the onsite energy via two-tone drives, which can be furthermore used to engineer artificial gauge potential. As an example, we show that the fer…
Enantiomeric excess determination based on nonreciprocal transition induced spectral line elimination
Xun-Wei Xu, Chong Ye, Yong Li +1
The spontaneous emission spectrum of a multi-level atom or molecule with nonreciprocal transition is investigated. It is shown that the nonreciprocal transition can lead to the eli…
Multiphoton blockade in the two-photon Jaynes-Cummings model
Fen Zou, Xiao-Ya Zhang, Xun-Wei Xu +2
We study multiphoton blockade and photon-induced tunneling effects in the two-photon Jaynes-Cummings model, where a single-mode cavity field and a two-level atom are coupled via a…
Nonreciprocity via nonlinearity and synthetic magnetism
Xun-Wei Xu, Yong Li, Baijun Li +2
We propose how to realize nonreciprocity for a weak input optical field via nonlinearity and synthetic magnetism. We show that the photons transmitting from a linear cavity to a no…
