The dynamical evolution of spin a massive probe fermion in hot QED plasma at local equilibrium is investigated through the quantum kinetic theory. We consider undergoing 2-by-2 Coulomb scattering with massless fermions medium. axial equation derived including collision terms to first order gradients and leading logarithmic coupling. are vanishing global equilibrium, around which relaxation time...

‎we characterize those groups $g$ and vector spaces $v$ such that $v$ is a faithful irreducible $g$-module and such that each $v$ in $v$ is centralized by a $g$-conjugate of a fixed non-identity element of the fitting subgroup $f(g)$ of $g$‎. ‎we also determine those $v$ and $g$ for which $v$ is a faithful quasi-primitive $g$-module and $f(g)$ has no regular orbit‎. ‎we do use these to show in ...

Abstract In this paper, we study the relativistic quantum dynamics of a neutral Dirac particle with permanent magnetic dipole moment that interacts an external field in background space-time linear topological defect called spiral dislocation. The generalized wave equation is derived from full action model involving Lagrangian density spinor and interaction model. energy eigenvalues correspondi...

We consider the effects of bound atomic electrons scattered by solar neutrinos due to electromagnetic properties neutrinos. This necessiate considering recoil nucleus, which should be considered in momentum conservation, but that effect energy conservation is negligible. changes kinematic behavior electron compared on free electrons. apply this recent XENON1T data, bounds obtained from not very...

Transmission Electron Microscopy Studies of Surface Phenomena in Polar Oxides Arun Kumar Subramanian Atomic scale processes at surfaces dictate the macroscopic properties of solid surfaces and have been the subject of numerous theoretical and experimental studies. Polar surfaces, due to their non-vanishing dipole moment along the surface normal, are unstable from classic electrostatics argument...

The ansatz of vanishing A and B parameters eliminates CP violating complex phases in soft supersymmetry-breaking parameters of the minimal supersymmetric standard model, and thus provides a simple solution to the supersymmetry CP problem. Phenomenological implications of this ansatz are investigated in the framework of minimal supergravity. We show that electroweak symmetry breakdown occurs, pr...

In this paper, we investigate compactly supported symmetric orthonormal dyadic complex wavelets such that the symmetric orthonormal refinable functions have high linear-phase moments and the antisymmetric wavelets have high vanishing moments. Such wavelets naturally lead to real-valued symmetric tight wavelet frames with some desirable moment properties, and are related to coiflets which are re...

The LeGall 5/3 and Daubechies 9/7 filters have risen to special prominence because they were selected for inclusion in the JPEG2000 standard. We determine their key mathematical features: Riesz bounds, order of approximation, and regularity (Hölder and Sobolev). We give approximation theoretic quantities such as the asymptotic constant for the L2 error and the angle between the analysis and syn...
