Semi-Metal-Insulator Transition of the Hubbard Model in the Honeycomb Lattice

- S. Sorella, E. Tosatti
- Physics
- 15 August 1992

Using quantum Monte Carlo and finite-size scaling for the Hubbard model, we find evidence of a zero-temperature transition between the nonmagnetic semi-metal and an antiferromagnetic insulator in the… Expand

Long-Range Néel Order in the Triangular Heisenberg Model

- L. Capriotti, A. Trumper, S. Sorella
- Physics
- 8 January 1999

We have studied the Heisenberg model on the triangular lattice using several Quantum Monte Carlo (QMC) techniques (up to 144 sites), and exact diagonalization (ED) (up to 36 sites). By studying the… Expand

Generalized Lanczos algorithm for variational quantum Monte Carlo

- S. Sorella
- Physics
- 11 September 2000

We show that the standard Lanczos algorithm can be efficiently implemented statistically and self-consistently improved, using the stochastic reconfiguration method, which has been recently… Expand

Universal quantum criticality in the metal-insulator transition of two-dimensional interacting Dirac electrons

- Y. Otsuka, S. Yunoki, S. Sorella
- Physics
- 29 October 2015

The metal-insulator transition has been a subject of intense research since Nevil Mott has first proposed that the metallic behavior of interacting electrons could turn to the insulating one as… Expand

Direct evidence for a gapless $Z_2$ spin liquid by frustrating Néel antiferromagnetism

- Wenjun Hu, F. Becca, A. Parola, S. Sorella
- Physics
- 9 April 2013

By direct calculations of the spin gap in the frustrated Heisenberg model on the square lattice, with nearest- ($J_1$) and next-nearest-neighbor ($J_2$) super-exchange couplings, we provide a solid… Expand

Gapless spin-liquid phase in the kagome spin-(1)/(2) Heisenberg antiferromagnet

- Y. Iqbal, F. Becca, S. Sorella, D. Poilblanc
- Physics
- 9 September 2012

We study the energy and the static spin structure factor of the ground state of the spin-1/2 quantum Heisenberg antiferromagnetic model on the kagome lattice. By the iterative application of a few… Expand

GREEN FUNCTION MONTE CARLO WITH STOCHASTIC RECONFIGURATION

- S. Sorella
- Physics
- 10 March 1998

A new method for the stabilization of the sign problem in the Green Function Monte Carlo technique is proposed. The method is devised for real lattice Hamiltonians and is based on an iterative… Expand

Stable liquid hydrogen at high pressure by a novel Ab initio molecular-dynamics calculation.

TLDR

Electron Localization in the Insulating State

- R. Resta, S. Sorella
- Physics
- 14 August 1998

The insulating state of matter is characterized by the excitation spectrum, but also by qualitative features of the electronic ground state. The insulating ground wavefunction in fact: (i) sustains… Expand
