Variational Monte Carlo method with tensor product wave function
Dr. Olga Sikora, National Taiwan University

Combining tensor network methods with variational Monte Carlo optimization is one of the promising methods of studying many body problems. We apply this approach in two-dimensions by using tensor-product based projection operators to optimize a variational wave function describing fermionic or bosonic systems. I will begin by introducing quantum variational Monte Carlo technique, then I will demonstrate our method for the tight binding model with nearest neighbors repulsion on a square lattice. Our study is motivated by a recent work by Chung-Pin Chou, Frank Pollmann and Ting-Kuo Lee, Phys. Rev. B 86, 041105(R), where matrix product based projected wave functions were considered as trial functions for Variational Monte Carlo simulations in one dimension.
We hope many of you will come !
