Destruction of Neel order in the cuprates by electron-doping
Ribhu K. Kaul, Max A. Metlitski, Subir Sachdev +1
Motivated by the evidence in PCCO and NCCO of a magnetic quantum critical point at which Neel order is destroyed, we study the evolution with doping of the T=0 quantum phases of th…

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)…
