The Yang-Mills vacuum wave functional thirty-five years later
Stefan Olejnik
The first paper attempting direct calculation of the Yang-Mills vacuum wave functional was published by Greensite in 1979. I review some recent results of the determination of the…
Measuring the ground-state wave functional of SU(2) Yang-Mills theory in 3+1 dimensions: Abelian plane waves
Jeff Greensite, Stefan Olejnik
A method of measuring relative probabilities of various gauge-field configurations in the Yang-Mills vacuum was proposed long ago [Phys. Lett. B 223 (1989) 207]. We applied this me…
Numerical study of the Yang-Mills vacuum wavefunctional in D=3+1 dimensions
Jeff Greensite, Stefan Olejnik
Ratios of the true Yang-Mills vacuum wavefunctional, evaluated on any two field configurations out of a finite set of configurations, can be obtained from lattice Monte Carlo simul…
Yang-Mills Theory in lambda-Gauges
Axel Maas, Tereza Mendes, Stefan Olejnik
The gauge-independent phenomenon of color confinement in Yang-Mills theory manifests itself differently in different gauges. Therefore, the gauge dependence of quantities related t…
Monopoles in the Plaquette Formulation of the 3D SU(2) Lattice Gauge Theory
O. Borisenko, S. Voloshyn, J. Boháčik
Using a plaquette formulation for lattice gauge models we describe monopoles of the three dimensional SU(2) theory which appear as configurations in the complete axial gauge and vi…
Adjoint torelons, and the persistence of color electric flux tubes in the deconfined phase
J. Greensite, S. Olejnik
It is argued that the adjoint torelon loop, i.e. a Polyakov loop in the adjoint representation running in a spatial, rather than temporal, direction, is an observable which is sens…
Testing Proposals for the Yang-Mills Vacuum Wavefunctional by Measurement of the Vacuum
J. Greensite, H. Matevosyan, S. Olejnik +3
We review a method, suggested many years ago, to numerically measure the relative amplitudes of the true Yang-Mills vacuum wavefunctional in a finite set of lattice-regulated field…
Coulomb Confinement from the Yang-Mills Vacuum State in 2+1 Dimensions
J. Greensite, S. Olejnik
The Coulomb-gauge ghost propagator, and the color-Coulomb potential, are computed in an ensemble of configurations derived from our recently proposed Yang-Mills vacuum wavefunction…
Properties of canonical fermion determinants with a fixed quark number
Julia Danzer, Christof Gattringer, Ludovit Liptak
Using a dimensional reduction formula for the lattice fermion determinant we study canonical determinants on quenched SU(3) gauge configurations. The canonical determinants decribe…
Vacuum structure and Casimir scaling in Yang-Mills theories
S. Olejnik
The vacuum of Yang-Mills theories can be imagined as a magnetically disordered medium with domain structure, with color magnetic flux in each domain quantized in units correspondin…
Gluon chains and the quark-antiquark potential
J. Greensite, S. Olejnik
The flux tube between a quark and an antiquark in Coulomb gauge is imagined in the gluon-chain model as a sequence of constituent gluons bound together by Coulombic nearest-neighbo…
A study of the sign problem for lattice QCD with chemical potential
Julia Danzer, Christof Gattringer, Ludovit Liptak +1
We study the expectation value of the phase of the fermion determinant for Wilson lattice fermions with chemical potential. We use quenched SU(3) ensembles and implement a recently…
Canonical fermion determinants in lattice QCD - Numerical evaluation and properties
Erek Bilgici, Julia Danzer, Christof Gattringer +2
We analyze canonical fermion determinants, i.e., fermion determinants projected to a fixed quark number q. The canonical determinants are computed using a dimensional reduction for…
Constituent Gluon Content of the Static Quark-Antiquark State in Coulomb Gauge
J. Greensite, S. Olejnik
Motivated by the gluon-chain model of flux tube formation, we compute and diagonalize the transfer matrix in lattice SU(2) gauge theory for states containing heavy static quark-ant…
First evidence for Casimir scaling in G(2) lattice gauge theory
L. Liptak, S. Olejnik
Potentials between static quarks and antiquarks from a few lowest representations were evaluated in numerical simulations of 4-dimensional pure G lattice gauge theory at variou…
More on Gribov copies and propagators in Landau-gauge Yang-Mills theory
Axel Maas
Fixing a gauge in the non-perturbative domain of Yang-Mills theory is a non-trivial problem due to the presence of Gribov copies. In particular, there are different gauges in the n…
Casimir scaling in G(2) lattice gauge theory
L. Liptak, S. Olejnik
We computed potentials between static color sources from the six lowest representations of G(2) lattice gauge theory, in numerical simulations with the Wilson action on asymmetric…
Center Vortices and the Dirac Spectrum
Manfried Faber, Jeff Greensite, Urs M. Heller +2
We study correlations between center vortices and the low-lying eigenmodes of the Dirac operator, in both the overlap and asqtad formulations. In particular we address a puzzle rai…
Linear Covariant Gauges on the Lattice
Attilio Cucchieri, Axel Maas, Tereza Mendes
Linear covariant gauges, such as Feynman gauge, are very useful in perturbative calculations. Their nonperturbative formulation is, however, highly non-trivial. In particular, it i…
Three-point vertices in Landau-gauge Yang-Mills theory
Attilio Cucchieri, Axel Maas, Tereza Mendes
Vertices are of central importance for constructing QCD bound states out of the individual constituents of the theory, i.e. quarks and gluons. In particular, the determination of t…
A first look at Landau-gauge propagators in G2 Yang-Mills theory
Axel Maas, Stefan Olejnik
G_2 Yang--Mills theory is an interesting laboratory to investigate non-perturbative effects. On one hand, no conventional quark confinement via a linearly rising potential is prese…
Dimensional Reduction and the Yang-Mills Vacuum State in 2+1 Dimensions
J. Greensite, S. Olejnik
We propose an approximation to the ground state of Yang-Mills theory, quantized in temporal gauge and 2+1 dimensions, which satisfies the Yang-Mills Schrodinger equation in both th…
Two- and three-point Green's functions in two-dimensional Landau-gauge Yang-Mills theory
Axel Maas
The ghost and gluon propagator and the ghost-gluon and three-gluon vertex of two-dimensional SU(2) Yang-Mills theory in (minimal) Landau gauge are studied using lattice gauge theor…
Energy density for chiral lattice fermions with chemical potential
Christof Gattringer, Ludovit Liptak
We study a recently proposed formulation of overlap fermions at finite density. In particular we compute the energy density as a function of the chemical potential and the temperat…
