Higgs Bosons in D-wave Superconductors
Yafis Barlas, C. M. Varma
The concept of "broken symmetry", that the symmetry of the vacuum may be lower than the Hamiltonian of a quantum theory, plays an important role in modern physics. A manifestation…

Berry phase and Anomalous Hall Effect in a Three-orbital Tight-binding Hamiltonian
Yan He, Joel Moore, C. M. Varma
We consider the Anomalous Hall (AH) state induced by interactions in a three-orbital per unit-cell model. To be specific we consider a model appropriate for the Copper-Oxide lattic…

A variational method in the problem of screening an external charge in strongly correlated metals
G. G. Guzmán-Verri, Arkady Shekhter, C. M. Varma
We describe a variational calculation for the problem of screening of a point charge in a layered correlated metal for dopings close to the Mott transition where the screening is n…
