چکیده
This note presents a method to reduce the discretization errors appearing when solving Quantum Field Theory in hypercubic lattice both position and momentum-space. The exploits artifacts that break rotational symmetry recover rotationally invariant results for two-point Green functions. We show combination of obtained momentum space can be useful signal presence making use their approximate Fourier transforms continuum. will introduced using Klein-Gordon propagator, direct application gluon propagator quenched QCD given.

Practical all-to-all propagators for lattice QCD
A new method for computing all elements of the lattice quark propagator is proposed. The method combines the spectral decomposition of the propagator, computing the lowest eigenmodes exactly, with noisy estimators which are ‘diluted’, i.e. taken to have support only on a subset of time, space, spin or colour. We find that the errors are dramatically reduced compared to traditional noisy estimat...
متن کاملOn rotational invariance of lattice Boltzmann schemes
We propose the derivation of acoustic-type isotropic partial differential equations that are equivalent to linear lattice Boltzmann schemes with a density scalar field and a momentum vector field as conserved moments. The corresponding linear equivalent partial differential equations are generated with a new “Berliner version” of the Taylor expansion method. The details of the implementation ar...
متن کاملPropagators, Running Coupling and Condensates in Lattice QCD
The strong force — one of the four fundamental interactions of nature along with gravity, electromagnetism and the weak force — is the force that holds together protons and neutrons in the nucleus. The strong interaction is described by Quantum Chromodynamics (QCD) [1]. This description is based on a model of elementary particles — the quarks — possessing “color charge” and interacting through ...
متن کاملRotational Invariance of Quadromer Correlations on the Hexagonal Lattice
In 1963 Fisher and Stephenson [FS] conjectured that the monomer-monomer correlation on the square lattice is rotationally invariant. In this paper we prove a closely related statement on the hexagonal lattice. Namely, we consider correlations of two quadromers (four-vertex subgraphs consisting of a monomer and its three neighbors) and show that they are rotationally invariant.
متن کاملYang-Mills Propagators and QCD ∗
We present a strong coupling expansion that permits to develop analysis of quantum field theory in the infrared limit. Application to a quartic massless scalar field gives a massive spectrum and the propagator in this regime. We extend the approach to a pure Yang-Mills theory obtaining analogous results. The gluon propagator is compared satisfactorily with lattice results and similarly for the ...
