Many-body Majorana-like zero modes without gauge symmetry breaking
Physical Review Research, 2021 Topological superconductors represent one of the key hosts of Majorana-based topological quantum computing. Typical scenarios for one-dimensional (1D) topological superconductivity assume a broken gauge symmetry associated to a superconducting state ...

(p − 1)-bracket for Dp-branes in large R-R field background
Journal of High Energy Physics, 2023 The volume-preserving diffeomorphism is a key feature that characterizes the large constant R-R (p − 1)-form field background in a Dp-brane theory. It represents a symmetry of the theory that preserves the volume of space.

Dynamical Symmetry Breaking of Extended Gauge Symmetries [PDF]
Physical Review Letters, 2003 We construct asymptotically free gauge theories exhibiting dynamical breaking of the left-right, strong-electroweak gauge group $G_{LR} = {\rm SU}(3)_c \times {\rm SU}(2)_L \times {\rm SU}(2)_R \times {\rm U}(1)_{B-L}$, and its extension to the Pati-Salam gauge group $G_{422}={\rm SU}(4)_{PS} \times {\rm SU}(2)_L \times {\rm SU}(2)_R$.

Gauge symmetry breaking in the adiabatic self-consistent collective coordinate method [PDF]
Prog. Theor. Exp. Phys. (2017) 2017 033D01, 2016 We study gauge symmetry breaking by adiabatic approximation in the adiabatic self-consistent collective coordinate (ASCC) method. In the previous study, we found that the gauge symmetry of the equation of collective submanifold is (partially) broken by its decomposition into the three moving-frame equations depending on the order of $p$. In this study,

Gauge Freedom in Path Integrals in Abelian Gauge Theory [PDF]
, 2015 We extend gauge symmetry of Abelian gauge field to incorporate quantum gauge degrees of freedom. We twice apply the Harada--Tsutsui gauge recovery procedure to gauge-fixed theories. First, starting from the Faddeev--Popov path integral in the Landau gauge, we recover the gauge symmetry by introducing an additional field as an extended gauge degree of ...

Comments on QCD3 and anomalies with fundamental and adjoint matter
Journal of High Energy Physics, 2022 ’t Hooft anomaly matching is powerful for constraining the low energy phases of gauge theories. In 3d one common anomaly is the parity anomaly in a T-symmetric theory where one cannot gauge the global symmetry group without breaking the time-reversal ...
