Nature of the Quantum Phase Transition in Quantum Compass Model
Han-Dong Chen, Chen Fang, Jiangping Hu +1
In this work, we show that the quantum compass model on an square lattice can be mapped to a fermionic model with local density interaction. We introduce a mean-field approximation…

Valence-bond crystal in a {111} slice of the pyrochlore antiferromagnet
Oleg Tchernyshyov, Hong Yao, R. Moessner
We investigate theoretically the ordering effect of quantum spin fluctuations in a Heisenberg antiferromagnet on a two-dimensional network of corner sharing tetrahedra. This networ…
