Computational methods for the fermion determinant and the link between overlap and domain wall fermions
Artan Borici
This paper reviews the most popular methods which are used in lattice QCD to compute the determinant of the lattice Dirac operator: Gaussian integral representation and noisy metho…

A note on ultraviolet suppressed quasi-optimal domain wall fermions
Artan Borici
In a recent work Chiu proposed to modify domain wall fermions that allow in an optimal way fewer number of flavors than in the standard case. This is done using a variant of doamin…

Fast methods for computing the Neuberger Operator
Artan Borici
I describe a Lanczos method to compute the Neuberger Operator and a multigrid algorithm for its inversion.

Truncated Overlap Fermions: the link between Overlap and Domain Wall Fermions
Artan Borici
In this talk I will emphasize the role of the Truncated Overlap Fermions in showing the equivalence between the Domain Wall and Overlap Fermions up to an irrelevant factor in the f…
