Phase Diagram of Spin-orbit Coupled Dipolar Fermions in a One-dimensional Optical Lattice
摘要
Abstract
We propose an experimental scheme to realize spin-orbit coupled dipolar fermions in a one-dimensional optical lattice by only utilizing two blue-detuned lasers,and then obtain its ground-state properties by the density matrix renormalization group.With both the on-site and dipole-dipole interactions,the system has rich quantum phases.By calculating entanglement spectrums,density distributions and spin-correlation functions,we predict four quantum phases,including a phase separation phase,a charge-density wave ohase,an antiferromagnetic Mott insulator,and a nontrivial topological insulator.关键词
