Directional Ordering of Fluctuations in a Two-dimensional Compass Model
Anup Mishra, Michael Ma, Fu-Chun Zhang +3
In the Mott insulating phase of the transition metal oxides, the effective orbital-orbital interaction is directional both in the orbital space and in the real space. We discuss a…

Plaquette Ordering in SU(4) Antiferromagnets
Anup Mishra, Michael Ma, Fu-Chun Zhang
We use fermion mean field theory to study possible plaquette ordering in the antiferromagnetic SU(4) Heisenberg model. We find the ground state for both the square and triangular l…
