Meron-Cluster Approach to Systems of Strongly Correlated Electrons
S. Chandrasekharan, J. Cox, J. C. Osborn +1
Numerical simulations of strongly correlated electron systems suffer from the notorious fermion sign problem which has prevented progress in understanding if systems like the Hubba…
Solution of the Complex Action Problem in the Potts Model for Dense QCD
M. Alford, S. Chandrasekharan, J. Cox +1
Monte Carlo simulations of lattice QCD at non-zero baryon chemical potential suffer from the notorious complex action problem. We consider QCD with static quarks coupled to a l…
Thermalization of Quantum Fields from Time-Reversal Invariant Evolution Equations
J. Berges, J. Cox
We study the time evolution of correlation functions in closed quantum systems for nonequilibrium ensembles of initial conditions. For a scalar quantum field theory we show that ge…
Meron-cluster algorithms and chiral symmetry breaking in a (2+1)-d staggered fermion model
J. Cox, K. Holland
The recently developed Meron-Cluster algorithm completely solves the exponentially difficult sign problem for a number of models previously inaccessible to numerical simulation. We…
Meron-Cluster Solution of Fermion and Other Sign Problems
J. Cox, C. Gattringer, K. Holland +2
Numerical simulations of numerous quantum systems suffer from the notorious sign problem. Important examples include QCD and other field theories at non-zero chemical potential, at…
Meron-Cluster Simulation of a Chiral Phase Transition with Staggered Fermions
S. Chandrasekharan, J. Cox, K. Holland +1
We examine a (3+1)-dimensional model of staggered lattice fermions with a four-fermion interaction and Z(2) chiral symmetry using the Hamiltonian formulation. This model cannot be…
