Tensor network models of AdS/qCFT [PDF]
Quantum, 2022 The study of critical quantum many-body systems through conformal field theory (CFT) is one of the pillars of modern quantum physics. Certain CFTs are also understood to be dual to higher-dimensional theories of gravity via the anti-de Sitter/conformal ...

Discrete Symmetries/Discrete Theories
, 2012 Dynamical, metastable supersymmetry breaking appears to be a generic phenomena in supersymmetric field theories. It's simplest implementation is within the so-called "retrofitted O'Raifeartaigh Models". While seemingly flexible, model building in these theories is significantly constrained. In gauge-mediated versions, if the approximate $R$ symmetry of

Exotic topological order in fractal spin liquids [PDF]
, 2013 We present a large class of three-dimensional spin models that possess topological order with stability against local perturbations, but are beyond description of topological quantum field theory. Conventional topological spin liquids, on a formal level,

Discrete symmetries of Dirac’s theory in the de Sitter manifold
European Physical Journal C: Particles and Fields, 2023 The discrete symmetries of Dirac’s free field on the de Sitter manifold are studied, taking into account that this has two portions that can play the role of physical space-times, namely an expanding and a collapsing universe.

Discrete Symmetries of Complete Intersection Calabi-Yau Manifolds
, 2017 In this paper, we classify non-freely acting discrete symmetries of complete intersection Calabi- Yau manifolds and their quotients by freely-acting symmetries.

Hamilton Operators, Discrete Symmetries, Brute Force and SymbolicC++ [PDF]
, 2012 To find the discrete symmetries of a Hamilton operator $\hat H$ is of central importance in quantum theory. Here we describe and implement a brute force method to determine the discrete symmetries given by permutation matrices for Hamilton operators ...

Green-Schwarz automorphisms and 6D SCFTs
Journal of High Energy Physics, 2018 All known interacting 6D superconformal field theories (SCFTs) have a tensor branch which includes anti-chiral two-forms and a corresponding lattice of string charges.

Note on Discrete Gauge Anomalies
, 1991 We consider the probem of gauging discrete symmetries. All valid constraints on such symmetries can be understood in the low energy theory in terms of instantons.

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.
