Note on gauge and gravitational anomalies of discrete Z N symmetries
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.

Symmetries of Discrete Systems
In this series of lectures presented at the CIMPA Winter School on Discrete Integrable Systems in Pondicherry, India, in February, 2003 we give a review of the application of Lie point symmetries, and their generalizations to the study of difference ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Metastability of Discrete-Symmetry Flocks
We study the stability of the ordered phase of flocking models with a scalar order parameter. Using both the active Ising model and a hydrodynamic description, we show that droplets of particles moving in the direction opposite to that of the ordered phase nucleate and grow.

Global symmetries of quantum lattice models under non-invertible dualities
Non-invertible dualities/symmetries have become an important tool in the study of quantum field theories and quantum lattice models in recent years. One of the most studied examples is non-invertible dualities obtained by gauging a discrete group.

ON PARTIAL DIFFERENTIAL AND DIFFERENCE EQUATIONS WITH SYMMETRIES DEPENDING ON ARBITRARY FUNCTIONS
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.

Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Minimal eclectic flavor group Q 8 ⋊ S 3 and neutrino mixing
We perform a comprehensive analysis of the minimal eclectic flavor group Q 8 ⋊ S 3 which is isomorphic to GL(2, 3), and all its irreducible representations are induced from the irreducible representations of Q 8 and S 3.

Discrete symmetries and 1/3-quantum vortices in condensates of F=2 cold atoms
In this Letter we study discrete symmetries of mean field manifolds of condensates of F=2 cold atoms, and various unconventional quantum vortices. Discrete quaternion symmetries result in two species of spin defects that can only appear in integer ...

Discrete symmetries of functional determinants [PDF]
We study discrete (duality) symmetries of functional determinants. An exact transformation of the effective action under the inversion of background fields $ (x) \to ^{-1}(x)$ is found. We show that in many cases this inversion does not change functional determinants.
