Disconnected 0-form and 2-group symmetries

open access: yesJournal of High Energy Physics, 2023
Quantum field theories can have both continuous and finite 0-form symmetries. We study global symmetry structures that arise when both kinds of 0-form symmetries are present. The global structure associated to continuous 0-form symmetries is described by

Bottom-Up Discrete Symmetries for Cabibbo Mixing [PDF]

open access: yes, 2016
We perform a bottom-up search for discrete non-Abelian symmetries capable of quantizing the Cabibbo angle that parameterizes CKM mixing. Given a particular Abelian symmetry structure in the up and down sectors, we construct representations of the ...

Generalized global symmetries and holography

open access: yesSciPost Physics, 2018
We study the holographic duals of four-dimensional field theories with 1-form global symmetries, both discrete and continuous. Such higher-form global symmetries are associated with antisymmetric tensor gauge fields in the bulk.

Discrete Space-Time Symmetries [PDF]

open access: yes, 1992
Symmetries have always fascinated human beings; they are found in nature, art, and architecture. Physicists, like other scientists have often used symmetries as a basis of their understanding of nature.

Proof of the universal density of charged states in QFT

open access: yesJournal of High Energy Physics, 2021
We prove a recent conjecture by Harlow and Ooguri concerning a universal formula for the charged density of states in QFT at high energies for global symmetries associated with finite groups. An equivalent statement, based on the entropic order parameter

Discrete symmetries from hidden sectors [PDF]

open access: yesJournal of High Energy Physics, 2015
We study the presence of abelian discrete symmetries in globally consistent orientifold compactifications based on rational conformal field theory. We extend previous work [1] by allowing the discrete symmetries to be a linear combination of U(1) gauge ...

How to Find Discrete Contact Symmetries [PDF]

open access: yes, 2017
This paper describes a new algorithm for determining all discrete contact symmetries of any differential equation whose Lie contact symmetries are known. The method is constructive and is easy to use.

Discrete Time Crystals in the Absence of Manifest Symmetries or Disorder in Open Quantum Systems. [PDF]

open access: yesPhysical Review Letters, 2018
We establish a link between metastability and a discrete time-crystalline phase in a periodically driven open quantum system. The mechanism we highlight requires neither the system to display any microscopic symmetry nor the presence of disorder, but ...

Large field excursions and approximate discrete symmetries from a clockwork axion [PDF]

open access: yes, 2015
We present a renormalizable theory of scalars in which the low-energy effective theory contains a pseudo-Goldstone boson with a compact field space of 2 pi F and an approximate discrete shift symmetry Z(Q) with Q >> 1, yet the number of fields in the ...

Leptonic Dirac CP Violation Predictions from Residual Discrete Symmetries [PDF]

open access: yes, 2015
Assuming that the observed pattern of 3-neutrino mixing is related to the existence of a (lepton) flavour symmetry, corresponding to a non-Abelian discrete symmetry group G f , and that G f is broken to specific residual symmetries G e and G ν of the ...
