Artificial electromagnetic field with cold atoms in two-dimensional optical lattice
Xiaoyong Guo, Yu Chen, Jian Liu
We propose that an artificial electromagnetic field can be engineered in the context of cold fermionic atoms that are coupled to a cavity mode via two-photon processes in a two-dim…
Dark-like states for the multi-qubit and multi-photon Rabi models
Jie Peng, Chenxiong zheng, Guangjie Guo +7
There are well-known dark states in the even-qubit Dicke models, which are the products of the two-qubit singlets and a Fock state, where the qubits are decoupled from the photon f…
Algebraic structure of the two-qubit quantum Rabi model and its solvability using Bogoliubov operators
Jie Peng, Zhongzhou Ren, Haitao Yang +6
We have found the algebraic structure of the two-qubit quantum Rabi model behind the possibility of its novel quasi-exact solutions with finite photon numbers by analyzing the Hami…
Phase-Entanglement Complementarity with Time-Energy Uncertainty
Fu-Lin Zhang, Mai-Lin Liang
We present a unified view of the Berry phase of a quantum system and its entanglement with surroundings. The former reflects the nonseparability between a system and a classical en…
Lower bound of local quantum uncertainty for high-dimensional bipartite quantum systems
Shuhao Wang, Hui Li, Xian Lu +2
Quantum correlations are of fundamental importance in quantum phenomena and quantum information processing studies. The measure of quantum correlations is one central issue. The re…
Locally maximally entangleable states and W-type states
Ri Qu, Juan Wang, Yan-ru Bao +1
We investigate the relationship between locally maximally entangleable (LME) states and W-type states which are equivalent to a W state under stochastic local operations and classi…
