Gauge origin of discrete flavor symmetries in heterotic orbifolds [PDF]

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.

Realization of a spontaneous gauge and supersymmetry breaking vacuum [PDF]

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

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 ...

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.

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

Instantons, symmetries and anomalies in five dimensions

Journal of High Energy Physics, 2021
All five-dimensional non-abelian gauge theories have a U(1) I global symmetry associated with instantonic particles. We describe an obstruction to coupling U(1) I to a classical background gauge field that occurs whenever the theory has a one-form center

Gauge enhanced quantum criticality and time reversal deconfined domain wall: SU(2) Yang-Mills dynamics with topological terms

Physical Review Research, 2020
We explore the low-energy dynamics of the four siblings of Lorentz symmetry enriched SU(2) Yang-Mills theories with a theta term at θ=π in (3+1)d. Due to a mixed anomaly between time reversal symmetry and the one-form center symmetry, the low-energy ...

Reducible gauge symmetry versus unfree gauge symmetry in Hamiltonian formalism

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.

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—
