Magnetically Stabilized Order. II: Critical states and algebraically ordered nematic spin liquids in one-dimensional optical lattices
Hui Zhai, Fei Zhou
We investigate the Zeeman-field-driven quantum phase transitions between singlet spin liquids and algebraically ordered O(2) nematic spin liquids of spin-one bosons in one-dimensio…
Magnetically Stabilized Nematic Order I: Three-Dimensional Bipartite Optical Lattices
F. Zhou, M. Snoek, J. Wiemer +1
We study magnetically stabilized nematic order for spin-one bosons in optical lattices. We show that the Zeeman field-driven quantum transitions between non-nematic Mott states and…
Spin-one bosons in low dimensional Mott insulating states
F. Zhou
We analyze the strong coupling limit of spin-one bosons in low dimensional Mott insulating states. In 1D lattices, for an odd number of bosons per site (), the ground state is…
Quantum Spin Nematic States in Bose-Einstein Condensates
Fei Zhou
We review some recent results on discrete symmetries and topological order in spinor Bose-Einstein condensates (BECs) of . For spin one bosons with two-body scatterings do…
Hidden topological order in Bose-Einstein Condensates
Fei Zhou
We show the existence of a new hidden topological order in (F=1) Bose-Einstein condensates (BEC) with antiferromagnetic interactions. Occurrence of this order is due to t…
Spin-1/2 Collective Excitations in BEC of Interacting Spin-1 Atoms
Fei Zhou
We construct spin-1/2 collective excitations in BEC of interacting spin-1 atoms. These excitations exist in states with a maximal global degeneracy. The stability and energy of the…
