Quantum Critical Point revisited by the Dynamical Mean Field Theory
Wenhu Xu, Gabriel Kotliar, Alexei M. Tsvelik
Dynamical mean field theory is used to study the quantum critical point (QCP) in the doped Hubbard model on a square lattice. The QCP is characterized by a universal scaling form o…

Giant Spin Gap and Magnon Localization in the Disordered Heisenberg Antiferromagnet Sr2Ir1-xRuxO4
Yue Cao, Xuerong Liu, Wenhu Xu +15
We study the evolution of magnetic excitations in the disordered two-dimensional antiferromagnet Sr2Ir1-xRuxO4. A gigantic magnetic gap greater than 40 meV opens at x = 0.27 and in…
