Single particle spectra of charge transfer insulators by cluster perturbation theory - the correlated band structure of NiO

R. Eder, A. Dorneich, H. Winter

We propose a many-body method for band-structure calculations in strongly correlated electron systems and apply it to NiO. The method may be viewed as a translationally invariant v…

Scaling properties of the projected SO(5) model in three dimensions

M. Jöstingmeier, A. Dorneich, E. Arrigoni +2

We study the scaling properties of the quantum ``projected'' SO(5) model in three dimensions by means of a highly accurate Quantum-Monte-Carlo analysis. Within the parameter regime…

Destruction of diagonal and off-diagonal long range order by disorder in two-dimensional hard core boson systems

K. Bernardet, G. G. Batrouni, M. Troyer +1

We use quantum Monte Carlo simulations to study the effect of disorder, in the form of a disordered chemical potential, on the phase diagram of the hard core bosonic Hubbard model…

Analytical and numerical study of hardcore bosons in two dimensions

K. Bernardet, G. G. Batrouni, J. -L. Meunier +3

We study various properties of bosons in two dimensions interacting only via onsite hardcore repulsion. In particular, we use the lattice spin-wave approximation to calculate the g…

Finite-Temperature Phase Diagram of Hard-Core Bosons in Two Dimensions

Guido Schmid, Synge Todo, Matthias Troyer +1

We determine the finite-temperature phase diagram of the square lattice hard-core boson Hubbard model with nearest neighbor repulsion using quantum Monte Carlo simulations. This mo…

Accessing the dynamics of large many-particle systems using Stochastic Series Expansion

A. Dorneich, M. Troyer

The Stochastic Series Expansion method (SSE) is a Quantum Monte Carlo (QMC) technique working directly in the imaginary time continuum and thus avoiding "Trotter discretization" er…
