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…
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…
Study of the order of the phase transition in pure U(1) gauge theory with Villain action
J. Cox, T. Neuhaus, H. Pfeiffer
We address the question of the order of the deconfinement phase transition of four dimensional U(1) lattice gauge theory. Simulations of the Z-gauge theory dual to the Villain acti…
Universality of the gauge-ball spectrum of the four-dimensional pure U(1) gauge theory
J. Cox, J. Jersak, H. Pfeiffer +3
We continue numerical studies of the spectrum of the pure U(1) lattice gauge theory in the confinement phase, initiated in our previous work. Using the extended Wilson action $ S =…
