Robust continuous symmetry breaking and multiversality in the chiral Dicke model
Nikolay Yegovtsev, Sayan Choudhury, W. Vincent Liu
The Dicke model (DM) serves as a paradigm for understanding collective light-matter interactions. We introduce the chiral Dicke model, a generalization where an atomic ensemble cou…

Double-exchange ferromagnetism of fermionic atoms in a -orbital hexagonal lattice
Haoran Sun, Erhai Zhao, Youjin Deng +1
A large class of correlated quantum materials feature strong Hund's coupling. Yet cold-atom quantum simulators have so far focused primarily on single-orbital Fermi-Hubbard systems…

Orbital Optical Raman Lattice
Zhi-Hao Huang, Kou-Han Ma, Bao-Zong Wang +2
Spin and orbital are two basic degrees of freedom that play significant roles in exploring exotic quantum phases in optical lattices with synthetic spin-orbit coupling (SOC) and hi…
