Dynamics and transport of the Z_2 spin liquid: application to kappa-(ET)2Cu2(CN)3
Yang Qi, Cenke Xu, Subir Sachdev
We describe neutron scattering, NMR relaxation, and thermal transport properties of Z_2 spin liquids in two dimensions. Comparison to recent experiments on the spin S=1/2 triangula…

Experimental observables near a nematic quantum critical point in the pnictide and cuprate superconductors
Cenke Xu, Yang Qi, Subir Sachdev
The newly discovered high temperature superconductor SmFeAs(O1-xFx) shows a clear nematic transition where the square lattice of Fe ions has a rectangular distortion. Similar nemat…

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)…
