Topological gauge fixing [PDF]

Modern Physics Letters A, 2014
We implement the metric-independent Fock-Schwinger gauge in the abelian quantum Chern-Simons field theory defined in ${\mathbb R}^3$. The expressions of the various components of the propagator are determined.

Gauge fixing for sequence-function relationships. [PDF]

PLoS Comput Biol
Quantitative models of sequence-function relationships are ubiquitous in computational biology, e.g., for modeling the DNA binding of transcription factors or the fitness landscapes of proteins.

Gauge invariance through gauge fixing. [PDF]

Studies in History and Philosophy of Science
Phenomena in gauge theory are often described in the physics literature via a specific choice of gauge. In foundational and philosophical discussions this is often criticized as introducing gauge dependence, and contrasted against (often aspirational) "gauge-invariant" descriptions of the physics.

Dressing vs. Fixing: On How to Extract and Interpret Gauge-Invariant Content. [PDF]

Found Phys
There is solid consensus among physicists and philosophers that, in gauge field theory, for a quantity to be physically meaningful or real, it must be gauge-invariant.

Smeared Gauge Fixing [PDF]

Nuclear Physics B - Proceedings Supplements, 1997
We present a new method of gauge fixing to standard lattice Landau gauge, Max Re Tr $\sum_{\mu,x}U_{\mu,x}$, in which the link configuration is recursively smeared; these smeared links are then gauge fixed by standard extremization.

Covariant gauge fixing and Kuchar decomposition [PDF]

Physical Review D, 1999
The symplectic geometry of a broad class of generally covariant models is studied. The class is restricted so that the gauge group of the models coincides with the Bergmann-Komar group and the analysis can focus on the general covariance.

The partial Bondi gauge: Gauge fixings and asymptotic charges [PDF]

SciPost Physics
In the companion paper [SciPost Phys. 13, 108 (2022)] we have studied the solution space at null infinity for gravity in the partial Bondi gauge. This partial gauge enables to recover as particular cases and among other choices the Bondi-Sachs and Newman-

Partial Gauge Fixing and Equivariant Cohomology [PDF]

Physical Review D, 2013
Given a gauge theory with gauge group G, it is sometimes useful to find an equivalent formulation in terms of a nontrivial gauge subgroup H⊂G. This amounts to fixing the gauge partially from G down to H.

Gauge fixing and gauge correlations in noncompact Abelian gauge models [PDF]

Physical Review D, 2023
We investigate some general properties of linear gauge fixings and gauge-field correlators in lattice models with noncompact U(1) gauge symmetry. In particular, we show that, even in the presence of a gauge fixing, some gauge-field observables (like the ...
