Flavor, CP and metaplectic modular symmetries in Type IIB chiral flux vacua
Journal of High Energy Physics, 2023 We examine symmetries of chiral four-dimensional vacua of Type IIB flux compactifications with vanishing superpotential W = 0. We find that the N $$ \mathcal{N} $$ = 1 supersymmetric MSSM-like and Pati-Salam vacua possess enhanced discrete symmetries in ...

Stringy Origin of Discrete R-symmetries [PDF]
, 2017 Discrete symmetries play a crucial role in particle physics. They appear abundantly in string model constructions. We focus here on the case of discrete $R$-symmetries which are intrinsically connected to the Lorentz group in extra dimensions and the ...

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Symmetries for the Semi-Discrete Lattice Potential Korteweg–de Vries Equation
MathematicsIn this paper, we prove that the isospectral flows associated with both the x-part and the n-part of the Lax pair of the semi-discrete lattice potential Korteweg–de Vries equation are symmetries of the equation.

Note on gauge and gravitational anomalies of discrete Z N symmetries
Journal of High Energy Physics, 2018 In this note, we discuss the consistency conditions which a discrete Z N symmetry should satisfy in order that it is not violated by gauge and gravitational instantons.

Viability of minimal left-right models with discrete symmetries [PDF]
, 2014 We provide a systematic study of minimal left-right models that are invariant under P, C, and/or CF transformations. Due to the high amount of symmetry such models are quite predictive in the amount and pattern of CF violation they can produce or ...

Discrete point symmetries of ordinary differential equations [PDF]
, 2017 This paper describes a method that enables the user to construct systematically the set of all discrete point symmetries of a given ordinary differential equation (ODE) of order two or greater, provided that the ODE has at least a one-parameter Lie group

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators
Advanced Engineering Materials, EarlyView.Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Symmetries, anomalies, and dualities of two-dimensional Non-Linear Sigma Models
Journal of High Energy PhysicsWe analyse the global symmetry structure of two-dimensional Non-Linear Sigma Models with Wess-Zumino term. When the target space has a compact isometry without fixed points, the theory has a pair of (group-like) global symmetries and many such theories ...

ON PARTIAL DIFFERENTIAL AND DIFFERENCE EQUATIONS WITH SYMMETRIES DEPENDING ON ARBITRARY FUNCTIONS
Acta Polytechnica, 2016 In this note we present some ideas on when Lie symmetries, both point and generalized, can depend on arbitrary functions. We show a few examples, both in partial differential and partial difference equations where this happens.
