M. Feldbacher, R. Arita, K. Held +1
Katsnelson submitted his Comment on our paper "Projective Quantum Monte Carlo Method for the Anderson Impurity Model and its Application to Dynamical Mean Field Theory" to Phys. Re…
Projective Quantum Monte Carlo Method for the Anderson Impurity Model and its Application to Dynamical Mean Field Theory
M. Feldbacher, K. Held, F. F. Assaad
We develop a projective quantum Monte Carlo algorithm of the Hirsch-Fye type for obtaining ground state properties of the Anderson impurity model. This method is employed to solve…
Spin and charge dynamics of the ferromagnetic and antiferromagnetic two-dimensional half-filled Kondo lattice model
S. Capponi, F. F. Assaad
We present a detailed numerical study of spin and charge dynamics of the two-dimensional Kondo lattice model with hopping t and exchange J. At T=0 and J > 0, the competition betwee…
Hole Dynamics in Two-Dimensional Antiferromagnetic Mott Insulators
F. F. Assaad, M. Imada
The dispersion relation of a doped hole in the half-filled 2D Hubbard model is shown to follow a k^4 law around the (0,pi) and (pi,0) points in the Brillouin zone. Upon addition of…
Metal-Insulator and Superconductor-Insulator Transitions in Correlated Electron Systems
Masatoshi Imada, Fakher F. Assaad, Hirokazu Tsunetsugu +1
Quantum transitions between the Mott insulator and metals by controlling filling in two-dimensional square lattice are characterized by a large dynamical exponent where the o…
SU(2)-spin Invariant Auxiliary Field Quantum Monte Carlo Algorithm for Hubbard models
F. F. Assaad
Auxiliary field quantum Monte Carlo methods for Hubbard models are generally based on a Hubbard-Stratonovitch transformation where the field couples to the z-component of the spin.…
