Algorithms for dynamical overlap fermions
Stefan Schaefer
An overview of the current status of algorithmic approaches to dynamical overlap fermions is given. In particular the issue of changing the topological sector is discussed.
Quark condensate in two-flavor QCD
Thomas DeGrand, Zhaofeng Liu, Stefan Schaefer
We compute the condensate in QCD with two flavors of dynamical fermions using numerical simulation. The simulations use overlap fermions, and the condensate is extracted by fitting…
Quark condensate in one-flavor QCD
Thomas DeGrand, Roland Hoffmann, Stefan Schaefer +1
We compute the condensate in QCD with a single quark flavor using numerical simulations with the overlap formulation of lattice fermions. The condensate is extracted by fitting the…
Simulating an arbitrary number of flavors of dynamical overlap fermions
Thomas DeGrand, Stefan Schaefer
We present a set of related Hybrid Monte Carlo methods to simulate an arbitrary number of dynamical overlap fermions. Each fermion is represented by a chiral pseudo-fermion field.…
