Ginsparg-Wilson Games

چکیده
Published algorithms[2] cost (apparently) hundreds of times as much as the usual clover action. I describe an approach which costs about a factor of 6.5×(N+1) as much as the clover action for an Nth order approximation, and even N = 1 looks quite promising. The ideas in this work are based on three remarkable formulas first published by Neuberger[3]: Introducing a zeroth-order Dirac operator D0 and defining z = 1 − D0/r0, a GW action (with R = r0) is

On the Absence of Ultralocal Ginsparg-Wilson Fermions
It was shown recently by I. Horváth that lattice fermions obeying the standard form of the Ginsparg-Wilson relation cannot be ultralocal. However, there are more general forms of the Ginsparg-Wilson relation, which also guarantee the physical chiral properties, but which are not covered by Horváth’s consideration. Here we extend his proof to a much larger class of Ginsparg-Wilson fermions, demo...
متن کاملOperator improvement for Ginsparg - Wilson fermions
The improvement of fermionic operators for Ginsparg-Wilson fermions is investigated. We present explicit formulae for improved Green’s functions, which apply both on-shell and off-shell.
متن کاملGinsparg-Wilson operators and a no-go theorem
If one uses a general class of Ginsparg-Wilson operators, it is known that CP symmetry is spoiled in chiral gauge theory for a finite lattice spacing and the Majorana fermion is not defined in the presence of chiral symmetric Yukawa couplings. We summarize these properties in the form of a theorem for the general GinspargWilson relation. The Ginsparg-Wilson relation[1] provides a convenient fra...

We discuss the improvement of bilinear fermionic operators for Ginsparg-Wilson fermions. We present explicit formulae for improved Green's functions, which apply both on-shell and off-shell.
متن کاملBlock renormalization group transformations and overlap fermions
In this preliminary work, I provide the outline of an argument (leaving the full proof to a future publication) that there exists a valid renormalization group blocking transformation which converts the continuum fermion action into a Ginsparg-Wilson lattice action. I construct the blocking for the massless overlap operator as a specific example, indicating how other Ginsparg-Wilson lattice Dir...
متن کاملNew approximate solutions of the Ginsparg - Wilson equation - tests in 2 - d
A new method for finding approximate solutions of the Ginsparg-Wilson equation is tested in 2-d. The Dirac operator is first constructed and then used in a dynamical simulation of the 2-flavor Schwinger model. We find a very small mass of the π-particle implying almost chirally symmetric fermions. The generalization of our method to 4-d is straightforward. Introduction The last two years have s...
