Natural R-Parity, \mu-term, and Fermion Mass Hierarchy From Discrete Gauge Symmetries [PDF]

, 2002
In the minimal supersymmetric Standard Model with seesaw neutrino masses we show how R-parity can emerge naturally as a discrete gauge symmetry. The same discrete symmetry explains the smallness of the \mu-term (the Higgsino mass parameter) via the ...

Anomaly constraints on gapped phases with discrete chiral symmetry [PDF]

Physical Review D, 2019
We prove that in $(3+1)d$ quantum field theories with ${\mathbb{Z}}_{N}$ symmetry, certain anomalies forbid a symmetry-preserving vacuum state with a gapped spectrum.

CP-odd invariants for multi-Higgs models and applications with discrete symmetry [PDF]

, 2017
CP-odd invariants are useful for studying the CP properties of Lagrangians in any basis. We explain how to build basis invariants for the scalar sector, and how to distinguish CP-odd invariants from CP-even invariants. Up to a certain order, we use these

Non-equilibrium entanglement asymmetry for discrete groups: the example of the XY spin chain [PDF]

Journal of Statistical Mechanics: Theory and Experiment, 2023
Entanglement asymmetry is a novel quantity that, using entanglement methods, measures how much a symmetry is broken in a part of an extended quantum system. So far, it has only been used to characterise the breaking of continuous Abelian symmetries.

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.

Tri-bimaximal mixing, discrete family symmetries, and a conjecture connecting the quark and lepton mixing matrices [PDF]

, 2003
Neutrino oscillation experiments (excluding the LSND experiment) suggest a tri-bimaximal form for the lepton mixing matrix. This form indicates that the mixing matrix is probably independent of the lepton masses, and suggests the action of an underlying ...

Continuous symmetry breaking in a two-dimensional Rydberg array [PDF]

Nature, 2022
A two-dimensional dipolar XY model with a continuous spin-rotational symmetry is realized using a programmable Rydberg quantum simulator, complementing recent studies using the Rydberg-blockade mechanism to realize Ising-type interactions showing ...

The effect of increasing heel height on lower limb symmetry during the back squat in trained and novice lifters

BMC Sports Science, Medicine and Rehabilitation, 2020
Background Symmetry during lifting is considered critical for allowing balanced power production and avoidance of injury. This investigation assessed the influence of elevating the heels on bilateral lower limb symmetry during loaded (50% of body weight)

Modular symmetry and non-Abelian discrete flavor symmetries in string compactification [PDF]

Physical Review D, 2018
We study the modular symmetry in magnetized D-brane models on $T^2$. Non-Abelian flavor symmetry $D_4$ in the model with magnetic flux $M=2$ (in a certain unit) is a subgroup of the modular symmetry.

Discrete Lorentz symmetry and discrete time translational symmetry

New Journal of Physics, 2018
The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are the manifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.
