Transition to an Insulating Phase Induced by Attractive Interactions in the Disordered Three-Dimensional Hubbard Model
Bhargavi Srinivasan, Giuliano Benenti, Dima L. Shepelyansky
We study numerically the interplay of disorder and attractive interactions for spin-1/2 fermions in the three-dimensional Hubbard model. The results obtained by projector quantum M…

Symmetrized PQMC Studies of the ground state of
Bhargavi Srinivasan, S. Ramasesha, H. R. Krishnamurthy
We develop a new version of the Projector Quantum Monte Carlo (SPQMC) method which preserves the symmetries of the system by simultaneously sampling all symmetr…

Variational Monte Carlo and Configurational Interaction Studies of and its Fragments
Bhargavi Srinivasan, S. Ramasesha, H. R. Krishnamurthy
The molecule and its fragments are studied using Configuration Interaction (CI) and Variational Monte Carlo (VMC) techniques, within the Hubbard model. Using benzene as a…
