A Numerical Study of the 2-Flavour Schwinger Model with Dynamical Overlap Hypercube Fermions
Wolfgang Bietenholz, Ivan Hip, Stanislav Shcheredin +1
We present numerical results for the 2-flavour Schwinger model with dynamical chiral lattice fermions. We insert an approximately chiral hypercube Dirac operator into the overlap f…
Schwinger model simulations with dynamical overlap fermions
Wolfgang Bietenholz, Stanislav Shcheredin, Jan Volkholz
We present simulation results for the 2-flavour Schwinger model with dynamical overlap fermions. In particular we apply the overlap hypercube operator at seven light fermion masses…
Simulation Results for U(1) Gauge Theory on Non-Commutative Spaces
Wolfgang Bietenholz, Antonio Bigarini, Jun Nishimura +3
We present numerical results for U(1) gauge theory in 2d and 4d spaces involving a non-commutative plane. Simulations are feasible thanks to a mapping of the non-commutative plane…
A non-perturbative study of non-commutative U(1) gauge theory
J. Nishimura, W. Bietenholz, Y. Susaki +1
We study U(1) gauge theory on a 4d non-commutative torus, where two directions are non-commutative. Monte Carlo simulations are performed after mapping the regularized theory onto…
Dynamical overlap fermion simulations with a preconditioned Hybrid Monte Carlo force
Jan Volkholz, Wolfgang Bietenholz, Stanislav Shcheredin
We present simulation results for the 2-flavour Schwinger model with dynamical Ginsparg-Wilson fermions. Our Dirac operator is constructed by inserting an approximately chiral hype…
A non-perturbative study of 4d U(1) non-commutative gauge theory -- the fate of one-loop instability
Wolfgang Bietenholz, Jun Nishimura, Yoshiaki Susaki +1
Recent perturbative studies show that in 4d non-commutative spaces, the trivial (classically stable) vacuum of gauge theories becomes unstable at the quantum level, unless one intr…
