Orbital analogue of quantum anomalous Hall effect in -band systems
Congjun Wu
We investigate the topological insulating states of the -band systems in optical lattices induced by the onsite orbital angular momentum polarization, which exhibit gapless edge…

Incommensurate superfluidity of bosons in a double-well optical lattice
Vladimir M. Stojanovic, Congjun Wu, W. Vincent Liu +1
We study bosons in the first excited Bloch band of a double-well optical lattice, recently realized at NIST. By calculating the relevant parameters from a realistic nonseparable la…

Orbital ordering and frustration of -band Mott-insulators
Congjun Wu
We investigate the general structure of orbital exchange physics in Mott-insulating states of -orbital systems in optical lattices. Orbital orders occur in both the triangular a…
