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…

Berry's Phases of Ground States of Interacting Spin-One Bosons: Chains of Monopoles and Monosegments
Jeroen Wiemer, Fei Zhou
We study Berry's connection potentials of many-body ground states of spin-one bosons with antiferromagnetic interactions in adiabatically varying magnetic fields. We find that Berr…
