Hydrodynamic gauge fixing and higher order hydrodynamic expansion [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2022
Hydrodynamics is a powerful emergent theory for the large-scale behaviours in many-body systems, quantum or classical. It is a gradient series expansion, where different orders of spatial derivatives provide an effective description on different length ...

Consistent gauge-fixing conditions in polymerized gravitational systems [PDF]

open access: yesPhysical Review D, 2021
For classical gravitational systems the lapse function and the shift vector are usually determined by imposing appropriate gauge fixing conditions and then demanding their preservation with respect to the dynamics generated by a canonical Hamiltonian ...

Decoding Topological Subsystem Color Codes Over the Erasure Channel Using Gauge Fixing [PDF]

open access: yesIEEE Transactions on Communications, 2021
Topological subsystem color codes (TSCCs) are an important class of topological subsystem codes that allow for syndrome measurement with only 2-body measurements. It is expected that such low complexity measurements can help in fault tolerance.

Subsystem Codes with High Thresholds by Gauge Fixing and Reduced Qubit Overhead [PDF]

open access: yesPhysical Review X, 2020
We introduce a technique that uses gauge fixing to significantly improve the quantum error correcting performance of subsystem codes. By changing the order in which check operators are measured, valuable additional information can be gained, and we ...

Gauge fixing and constrained dynamics [PDF]

open access: yesThe European Physical Journal Plus, 2021
We review the Dirac formalism for dealing with constraints in a canonical Hamiltonian formulation and discuss gauge freedom and display constraints for gauge theories in a general context. We introduce the Dirac bracket and show that it provides a consistent method to remove any gauge freedom present. We discuss stability in evolution of gauge theories

Gauge fixing for strongly correlated electrons coupled to quantum light [PDF]

open access: yes, 2020
We discuss the problem of gauge fixing for strongly correlated electrons coupled to quantum light, described by projected low-energy models such as those obtained within tight-binding methods.

Asymptotic Symmetries in the Gauge fixing Approach and the BMS group [PDF]

open access: yesProceedings of XV Modave Summer School in Mathematical Physics — PoS(Modave2019), 2019
These notes are an introduction to asymptotic symmetries in gauge theories, with a focus on general relativity in four dimensions. We explain how to impose consistent sets of boundary conditions in the gauge fixing approach and how to derive the ...

Cohomological analysis of gauge-fixed gauge theories [PDF]

open access: yesPhysics Letters B, 2000
The relation between the gauge-invariant local BRST cohomology involving the antifields and the gauge-fixed BRST cohomology is clarified. It is shown in particular that the cocycle conditions become equivalent once it is imposed, on the gauge-fixed side, that the BRST cocycles should yield deformations that preserve the nilpotency of the (gauge-fixed ...
