Hole dynamics in a quantum antiferromagnet beyond the retraceable path approximation
Q. F. Zhong, S. Sorella, A. Parola
The one-hole spectral weight for two chains and two dimensional lattices is studied numerically using a new method of analysis of the spectral function within the Lanczos iteration…
Realization of a Spin liquid in a Two Dimensional Quantum Antiferromagnet
A. Parola, S. Sorella, Q. F. Zhong
The ground state properties of the two dimensional spatially anisotropic Heisenberg model are investigated by use of field theory mappings, spin-wave expansion and Lanczos techniqu…
Numerical Evidence of Luttinger and Fermi Liquid Behaviour in the 2D Hubbard Model
Sandro Sorella
The two dimensional Hubbard model with a single spin-up electron interacting with a finite density of spin-down electrons is studied using the quantum Monte Carlotechnique, a new c…
Phase separation in the large-spin {\it t}-{\it J} model
Antimo Angelucci, Sandro Sorella
We investigate the phase diagram of the two dimensional {\it t}-{\it J} model using a recently developed technique that allows to solve the mean-field model hamiltonian with a vari…
