The discrete Green-Schwarz mechanism in 6D F-theory and elliptic genera of non-critical strings

open access: yesJournal of High Energy Physics, 2023
We study global anomalies of discrete gauge symmetries in six-dimensional supergravities and their realizations in F-theory. We explicitly construct a discrete Green-Schwarz mechanism that depends on the choice of a coupling constant and on a certain ...

The discrete Burgers equation

open access: yesPartial Differential Equations in Applied Mathematics, 2022
In this paper I give a short review on the continuous, semi-discrete and discrete Burgers equations, which are featured as integrable equations that are linearisable.

Alternative Schemes of Predicting Lepton Mixing Parameters from Discrete Flavor and CP Symmetry [PDF]

open access: yes, 2016
We suggest two alternative schemes to predict lepton mixing angles as well as $CP$ violating phases from a discrete flavor symmetry group combined with $CP$ symmetry. In the first scenario, the flavor and $CP$ symmetry is broken to the residual groups of

Fine Structure of Matrix Darboux-Toda Integrable Mapping [PDF]

open access: yes, 1998
We show here that matrix Darboux-Toda transformation can be written as a product of a number of mappings. Each of these mappings is a symmetry of the matrix nonlinear Shrodinger system of integro-differential equations. We thus introduce a completely new

Anomaly matching in the symmetry broken phase: Domain walls, CPT, and the Smith isomorphism

open access: yesSciPost Physics, 2020
Symmetries in Quantum Field Theory may have 't Hooft anomalies. If the symmetry is unbroken in the vacuum, the anomaly implies a nontrivial low-energy limit, such as gapless modes or a topological field theory. If the symmetry is spontaneously broken,

Ferromagnets, a new anomaly, instantons, and (noninvertible) continuous translations

open access: yesSciPost Physics
We discuss a large class of classical field theories with continuous translation symmetry. In the quantum theory, a new anomaly explicitly breaks this translation symmetry to a discrete symmetry.

Discrete Symmetries from Broken $SU(N)$ and the MSSM

open access: yes, 1992
In order that discrete symmetries should not be violated by gravitational effects, it is necessary to gauge them. In this paper we discuss the gauging of $\Z_N$ from the breaking of a high energy $SU(N)$ gauge symmetry, and derive consistency conditions ...

Condensed matter physics in time crystals

open access: yesNew Journal of Physics, 2020
Time crystals are physical systems whose time translation symmetry is spontaneously broken. Although the spontaneous breaking of continuous time-translation symmetry in static systems is proved impossible for the equilibrium state, the discrete time ...

On discrete Lorenz attractors of various types [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
The purpose of this work is to develop the theory of discrete attractors of Lorenz type in the case of three-dimensional maps. In this case, special attention will be paid to standard discrete Lorenz attractors, as well as discrete Lorenz attractors with

On the Anomalous Discrete Symmetry

open access: yes, 1992
We examine an interesting scenario to solve the domain wall problem recently suggested by Preskill, Trivedi, Wilczek and Wise. The effective potential is calculated in the presence of the QCD axial anomaly.
