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…
