Reducible gauge symmetry versus unfree gauge symmetry in Hamiltonian formalism [PDF]

Nuclear Physics B, 2021
The unfree gauge symmetry implies that gauge variation of the action functional vanishes provided for the gauge parameters are restricted by the differential equations.

Discrete theta angles, symmetries and anomalies

SciPost Physics, 2021
Gauge theories in various dimensions often admit discrete theta angles, that arise from gauging a global symmetry with an additional symmetry protected topological (SPT) phase.

Parity from gauge symmetry

European Physical Journal C: Particles and Fields, 2022
We argue that Left-Right parity symmetry $${\mathcal {P}}$$ P can arise as a discrete remnant of a unified gauge symmetry. The high-energy unification necessarily includes the gauging of the Lorentz symmetry, bringing into the game gravitational ...

Symmetry-enriched quantum spin liquids in (3 + 1)d

Journal of High Energy Physics, 2020
We use the intrinsic one-form and two-form global symmetries of (3+1)d bosonic field theories to classify quantum phases enriched by ordinary (0-form) global symmetry. Different symmetry-enriched phases correspond to different ways of coupling the theory

A note on unfree gauge symmetry

Nuclear Physics B, 2019
We study the general structure of field theories with the unfree gauge symmetry where the gauge parameters are restricted by differential equations.

Gauge origin of discrete flavor symmetries in heterotic orbifolds

Physics Letters B, 2014
We show that non-Abelian discrete symmetries in orbifold string models have a gauge origin. This can be understood when looking at the vicinity of a symmetry enhanced point in moduli space.

Fractons, dipole symmetries and curved spacetime

SciPost Physics, 2022
We study complex scalar theories with dipole symmetry and uncover a no-go theorem that governs the structure of such theories and which, in particular, reveals that a Gaussian theory with linearly realised dipole symmetry must be Carrollian.

5D N=1 super QFT: Symplectic quivers

Nuclear Physics B, 2022
We develop a method to build new 5D N=1 gauge models based on Sasaki-Einstein manifolds Yp,q. These models extend the standard 5D ones having a unitary SU(p)q gauge symmetry based on Yp,q.

Realization of a spontaneous gauge and supersymmetry breaking vacuum

Journal of High Energy Physics, 2017
It is one of the major issues to realize a vacuum which breaks supersymmetry (SUSY) and R-symmetry, in a supersymmetric model. We study the model, where the same sector breaks the gauge symmetry and SUSY. In general, the SUSY breaking model without gauge

Categorical symmetry and noninvertible anomaly in symmetry-breaking and topological phase transitions

Physical Review Research, 2020
For a zero-temperature Landau symmetry-breaking transition in n-dimensional space that completely breaks a finite symmetry G, the critical point at the transition has the symmetry G. In this paper, we show that the critical point also has a dual symmetry—
