Nonreciprocal transition between two indirectly coupled energy levels
Xun-Wei Xu, Hai-Quan Shi, Ai-Xi Chen
We propose a theoretical scheme to realize nonreciprocal transition between two energy levels that can not coupled directly. Suppose they are coupled indirectly by two auxiliary le…

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…
