Spontaneous polarized phase transitions and symmetry breaking in the imbalanced Dicke model
Jinling Lian, Ran Huang, Chao Gao +3
We investigate the ground-state properties and quantum phase transitions of an ensemble consisting of four-level atoms within an optical cavity coupled to the single cavity mod…
Two-dimensional topological effect in a transmon qubit array with tunable couplings
Yan-Jun Zhao, Yu-Qi Wang, Yang Xue +4
We investigate a square-lattice architecture of superconducting transmon qubits with inter-qubit interactions mediated by inductive couplers. Therein, the inductive couling between…
Logarithmic light cone, slow entanglement growth, and quantum memory
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +4
Effective light cones, characterized by Lieb-Robinson bounds, emerge in nonrelativistic local quantum systems. Here, we present several analytical results derived from logarithmic…
Optimized fringe removal algorithm for absorption images
Linxiao Niu, Xinxin Guo, Yuan Zhan +3
Optical absorption imaging is a basic detection technique for obtaining information from matter waves, in which the absorption signal can be obtained by comparing the recorded dete…
Comments on "Controlling Discrete and Continuous Symmetries in Superradiant Phase Transitions with Circuit QED Systems "
Yu Yi-Xiang, Jinwu Ye, W. M. Liu +1
Recently, the authors of the commented PRL presented the solution of the Dicke model studied by us previously. Here we point out that (1) The authors miss…
An Important Properties of Entanglement: Pairwise Entanglement can Only be Transferred by Entangled Pair
Xiao-Qiang Xi, W. M. Liu
Basing on the calculation of all the pairwise entanglement in the ()-qubit Heisenberg XX open chain with system impurity, we find an important result: pairwise entang…
