Quantum Phase Transitions beyond the Landau's Paradigm in Sp(4) Spin System
Yang Qi, Cenke Xu
We propose quantum phase transitions beyond the Landau's paradigm of Sp(4) spin Heisenberg models on the triangular and square lattices, motivated by the exact Sp(4) SO(5)…

Insulator-metal transition on the triangular lattice
Yang Qi, Subir Sachdev
Mott insulators with a half-filled band of electrons on the triangular lattice have been recently studied in a variety of organic compounds. All of these compounds undergo transiti…
