The Travelling Cluster Approximation for Strong Correlation Models of Lattice Fermions Coupled to Classical Fields
Sanjeev Kumar, Pinaki Majumdar
We suggest and implement a new Monte Carlo strategy for correlated models involving fermions strongly coupled to classical degrees of freedom, with accurate handling of quenched di…
Anomalous Hall Effect in Double Exchange Magnets
Yong Baek Kim, Pinaki Majumdar, A. J. Millis +1
We investigate the possible origin of anomalous Hall effect in the CMR (colossal magnetoresistance) materials - the doped rare earth manganites - observed recently by Matl et al. I…
van Hove Singularity effects in Strongly Correlated Fermions
Pinaki Majumdar, H. R. Krishnamurthy
We examine the effects of a van Hove singularity (vHs) in the density of states (DOS) of a two dimensional, Hubbard model within the local approximation. Within our approx…
Hall Coefficient in the doped Mott Insulator
Pinaki Majumdar, H. R. Krishnamurthy
We compute the (zero frequency) Hall coefficient , and the high frequency Hall constant for the strong coupling Hubbard model away from half-filling, in the …
