Exotic topological density waves in cold atomic Rydberg fermions
Xiaopeng Li, S. Das Sarma
Versatile controllability of interactions in ultracold atomic and molecular gases has now reached an unprecedented era where quantum correlations and unconventional many-body phase…
Damping of long wavelength collective modes in spinor Bose-Fermi mixtures
J. H. Pixley, Xiaopeng Li, S. Das Sarma
Using an effective field theory we describe the low energy bosonic excitations in a three dimensional ultra-cold mixture of spin-1 bosons and spin-1/2 fermions. We establish an int…
Striped Ferronematic ground states in a spin-orbit coupled Bose gas
Stefan S. Natu, Xiaopeng Li, William S. Cole
We theoretically establish the mean-field phase diagram of a homogeneous spin-, spin-orbit coupled Bose gas as a function of the spin-dependent interaction parameter, the Raman…
Spontaneous quantum Hall effect in an atomic spinor Bose-Fermi mixture
Zhi-Fang Xu, Xiaopeng Li, Peter Zoller +1
We study a mixture of spin- bosonic and spin- fermionic cold atoms, e.g., Rb and Li, confined in a triangular optical lattice. With fermions at filling,…
Weyl Superfluidity in a Three-dimensional Dipolar Fermi Gas
Bo Liu, Xiaopeng Li, Lan Yin +1
Weyl superconductivity or superfluidity, a fascinating topological state of matter, features novel phenomena such as emergent Weyl fermionic excitations and anomalies. Here we repo…
Chiral spin superfluidity and spontaneous spin Hall effect of interacting bosons
Xiaopeng Li, Stefan S. Natu, Arun Paramekanti +1
Recent experiments on ultracold atoms in optical lattices have synthesized a variety of tunable bands with degenerate double-well structures in momentum space. Such degeneracies in…
