Critical behaviour near the metal-insulator transition of a doped Mott insulator
Y. Ono, R. Bulla, A. C. Hewson +1
We have studied the critical behaviour of a doped Mott insulator near the metal-insulator transition for the infinite-dimensional Hubbard model using a linearized form of dynamical…
The low-energy scale of the periodic Anderson model
Th. Pruschke, R. Bulla, M. Jarrell
Wilson's Numerical Renormalization Group method is used to study the paramagnetic ground state of the periodic Anderson model within the dynamical mean-field approach. For the part…
Reentrant charge order transition in the extended Hubbard model
R. Pietig, R. Bulla, S. Blawid
We study the extended Hubbard model with both on-site and nearest neighbor Coulomb repulsion ( and , respectively) in the Dynamical Mean Field theory. At quarter filling, the…
Anderson impurity in pseudo-gap Fermi systems
R. Bulla, Th. Pruschke, A. C. Hewson
We use the numerical renormalization group method to study an Anderson impurity in a conduction band with the density of states varying as rho(omega) \propto |omega|^r with r>0. We…
