Fermi liquid instabilities in the spin channel
Congjun Wu, Kai Sun, Eduardo Fradkin +1
We study the Fermi surface instabilities of the Pomeranchuk type in the spin triplet channel with high orbital partial waves (). The ordered phases are classified i…
Band Collapse and the Quantum Hall Effect in Graphene
B. Andrei Bernevig, Taylor L. Hughes, Han-Dong Chen +2
The recent Quantum Hall experiments in graphene have confirmed the theoretically well-understood picture of the quantum Hall (QH) conductance in fermion systems with continuum Dira…
Prediction of quantum stripe ordering in optical lattices
Congjun Wu, W. Vincent Liu, Joel Moore +1
We predict the robust existence of a novel quantum orbital stripe order in the -band Bose-Hubbard model of two-dimensional triangular optical lattices with cold bosonic atoms. A…
One-dimensional spin pyrochlore lattice: exact ground state and elementary excitations
Shu Chen, Yupeng Wang, W. Q. Ning +2
We study the antiferromagnetic spin exchange models with and S=1 on a one-dimensional tetrahedron chain by both analytical and numerical approaches. The system is shown to…
Atomic matter of non-zero momentum Bose-Einstein condensation and orbital current order
W. Vincent Liu, Congjun Wu
The paradigm of Bose-Einstein condensation has been associated with zero momentum to which a macroscopic fraction of bosons condense. Here we propose a new quantum state where boso…
