Anomaly of discrete family symmetries and gauge coupling unification [PDF]
, 2006 Anomaly of discrete symmetries can be defined as the Jacobian of the path-integral measure. We assume that an anomalous discrete symmetry at low energy is remnant of an anomaly free discrete symmetry, and that its anomaly is cancelled by the Green ...

Fusion category symmetry. Part I. Anomaly in-flow and gapped phases
Journal of High Energy PhysicsWe study generalized discrete symmetries of quantum field theories in 1+1D generated by topological defect lines with no inverse. In particular, we describe ’t Hooft anomalies and classify gapped phases stabilized by these symmetries, including new 1+1D ...

Metastability of Discrete-Symmetry Flocks. [PDF]
Physical Review Letters, 2023 We study the stability of the ordered phase of flocking models with a scalar order parameter. Using both the active Ising model and a hydrodynamic description, we show that droplets of particles moving in the direction opposite to that of the ordered ...

Exploring multi-Higgs models with softly broken large discrete symmetry groups [PDF]
The European Physical Journal C, 2021 We develop methods to study the scalar sector of multi-Higgs models with large discrete symmetry groups that are softly broken. While in the exact symmetry limit, the model has very few parameters and can be studied analytically, proliferation of ...

Model of Persistent Breaking of Discrete Symmetry. [PDF]
Physical Review Letters, 2021 We show there exist UV-complete field-theoretic models in general dimension, including 2+1, with the spontaneous breaking of a global symmetry, which persists to the arbitrarily high temperatures.

Discrete chiral symmetry and mass shift in the lattice Hamiltonian approach to the Schwinger model [PDF]
Physical Review Research, 2022 We revisit the lattice formulation of the Schwinger model using the Kogut-Susskind Hamiltonian approach with staggered fermions. This model, introduced by Banks et al., contains the mass term $m_{\rm lat} \sum_{n} (-1)^{n} \chi^\dagger_n \chi_n$, and ...

Discrete symmetry tests using hyperon-antihyperon pairs [PDF]
EPJ Web of Conferences, 2023 The BESIII experiment has accumulated millions of spin entangled hyperon–antihyperon pairs from the decays of the J/ψ and ψ(2S ) mesons produced in electron–positron collisions.

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.

Construction of Discrete Symmetries Using the Pauli Algebra Form of the Dirac Equation
Physical Sciences Forum, 2023 Two equations whose variables take values in the Pauli algebra of complex quaternions are shown to be equivalent to the standard Dirac equation and its Hermitian conjugate taken together.

Colloquium : Quantum and classical discrete time crystals [PDF]
Reviews of Modern Physics, 2023 The spontaneous breaking of time translation symmetry has led to the discovery of a new phase of matter - the discrete time crystal. Discrete time crystals exhibit rigid subharmonic oscillations, which result from a combination of many-body interactions,
