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 …
