Fast evaluation and locality of overlap fermions
W. Bietenholz, I. Hip, K. Schilling
In order to construct improved overlap fermions, we start from a short ranged approximate Ginsparg-Wilson fermion and insert it into the overlap formula. We show that its polynomia…

How to compute Green's Functions for entire Mass Trajectories within Krylov Solvers
U. Glaessner, S. Guesken, Th. Lippert +3
The availability of efficient Krylov subspace solvers play a vital role for the solution of a variety of numerical problems in computational science. Here we consider lattice field…

Specific Heat Exponent for the 3-d Ising Model from a 24-th Order High Temperature Series
G. Bhanot, M. Creutz, U. Glaessner +1
We compute high temperature expansions of the 3-d Ising model using a recursive transfer-matrix algorithm and extend the expansion of the free energy to 24th order. Using ID-Pade a…
