A New Gauge Fixing Method for Abelian Projection [PDF]
, 2000 We formulate a stochastic gauge fixing method to study the gauge dependence of the Abelian projection. We consider a gauge which interpolates between the maximal Abelian gauge and no gauge fixing.

Gauge-fixing approach to lattice chiral gauge theories [PDF]
Nuclear Physics B - Proceedings Supplements, 1998 We review the status of our recent work on the gauge-fixing approach to lattice chiral gauge theories. New numerical results in the reduced version of a model with a U(1) gauge symmetry are presented which strongly indicate that the factorization of the correlation functions of the left-handed neutral and right-handed charged fermion fields, which we ...

The `BRST-invariant' Condensate of Dimension Two in QCD [PDF]
, 2003 The status of the `BRST-invariant' condensate of mass dimension two in QCD is explained. The condensate is only invariant under an `on-shell' BRST symmetry which includes a partial gauge-fixing.

A gauge-fixing action for lattice gauge theories [PDF]
Physics Letters B, 1997 We present a lattice gauge-fixing action $S_{gf}$ with the following properties: (a) $S_{gf}$ is proportional to the trace of $(\sum_ \partial_ A_ )^2$, plus irrelevant terms of dimension six and higher; (b) $S_{gf}$ has a unique absolute minimum at $U_{x, }=I$.

Lorenz Gauge Fixing of $f(T)$ Teleparallel Cosmology [PDF]
, 2017 In teleparallel gravity, we apply Lorenz type gauge fixing to cope with redundant degrees of freedom in the vierbein field. This condition is mainly to restore the Lorentz symmetry of the teleparallel torsion scalar.

Gauge-Fixed Fourier Acceleration
Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2022 For an asymptotically free theory, a promising strategy for eliminating Critical Slowing Down (CSD) is naïve Fourier acceleration. This requires the introduction of gauge-fixing into the action, in order to isolate the asymptotically decoupled Fourier modes.

Nuclear Physics B, 1995 It has previously been shown that a BRST quantization on an inner product space leads to physical states of the form |ph>=e^[Q, \psi] |\phi> where |\phi> is either a trivially BRST invariant state which only depends on the matter variables, |\phi>_1, or a solution of a Dirac quantization, |\phi>_2.

A global optimization method for Landau gauge fixing in Lattice QCD [PDF]
, 2004 An algorithm for gauge fixing to the minimal Landau gauge in lattice QCD is described. The method, a combination of an evolutionary algorithm with a steepest descent method, is able to solve the problem of the nonperturbative gauge fixing.

Fundamental theorem on gauge fixing at the action level [PDF]
, 2016 Regardless of the long history of gauge theories, it is not well recognized under which condition gauge fixing at the action level is legitimate. We address this issue from the Lagrangian point of view, and prove the following theorem on the relation ...
