Multiple gauge fixing conditions [PDF]
We consider how more than one gauge fixing condition can be accommodated within the Feynman path integral both by extending the Faddeev–Popov procedure and the Batalin–Vilkovisky approach. The first-order Einstein–Hilbert action in 1 + 1 dimensions and the massless spin-3/2 action are considered.

Gaugeon Formalism for Spin-3/2 Rarita-Schwinger Gauge Field [PDF]
We provide a gauge covariant formalism of the canonically quantized theory of spin-3/2 Rarita-Schwinger gauge field. The theory admits a quantum gauge transformation by which we can shift the gauge fixing parameter.

A gauge fixing procedure for causal fermion systems [PDF]
Causal fermion systems incorporate local gauge symmetry in the sense that the Lagrangian and all inherent structures are invariant under local phase transformations of the physical wave functions.

Hamiltonian formalism and gauge-fixing conditions for cosmological perturbation theory [PDF]
We apply the Dirac procedure for constrained systems to the Arnowitt–Deser–Misner formalism linearized around the Friedmann–Lemaitre universe. We explain and employ some basic concepts such as Dirac observables, Dirac brackets, gauge-fixing conditions ...

Improved Landau Gauge Fixing and Discretisation Errors [PDF]
Lattice discretisation errors in the Landau gauge condition are examined. An improved gauge fixing algorithm in which order a^2 errors are removed is presented.

Non-equilibrium thermodynamics as gauge fixing [PDF]
By considering a thermodynamic force as gauge field, we extend constitutive equations of Onsager's non-equilibrium thermodynamics to non-linear equations.

Gauge fixing in (2+1)-gravity with vanishing cosmological constant [PDF]
We apply Dirac's gauge fixing procedure to (2+1)-gravity with vanishing cosmological constant. For general gauge fixing conditions based on two point particles, this yields explicit expressions for the Dirac bracket.

BRST gauge fixing and regularization [PDF]
In the presence of consistent regulators, the standard procedure of BRST gauge fixing (or moving from one gauge to another) can require non-trivial modifications. These modifications occur at the quantum level, and gauges exist which are only well-defined when quantum mechanical modifications are correctly taken into account.

Stochastic gauge fixing for N = 1 supersymmetric Yang-Mills theory [PDF]
The gauge fixing procedure for N=1 supersymmetric Yang-Mills theory (SYM) is proposed in the context of the stochastic quantization method (SQM). The stochastic gauge fixing, which was formulated by Zwanziger for Yang-Mills theory, is extended to SYM_4 ...

Lattice gauge-fixing for generic covariant gauges [PDF]
We propose a method which allows the generalization of the Landau lattice gauge-fixing procedure to generic covariant gauges. We report preliminary numerical results showing how the procedure works for $SU(2)$ and $SU(3)$. We also report numerical results showing that the contribution of finite lattice-spacing effects and/or spurious copies are ...
