The investigation of spin and polarization effects in ultra-high intensity laser–plasma laser–beam interactions has become an emergent topic high-field science recently. In this paper, we derive a relativistic kinetic description spin-polarized plasmas, where quantum-electrodynamics are taken into account via Boltzmann-type collision operators under the local constant field approximation. emerg...

This paper presents a noncommutative (NC) version of an extended S\'{a}ez-Ballester (SB) theory. Concretely, considering the spatially flat Friedmann-Lema\^{\i}tre-Robertson-Walker~(FLRW) metric, we propose appropriate dynamical deformation between conjugate momenta and applying Hamiltonian formalism, obtain deformed equations motion. In our model, NC parameter appears linearly in Poisson brack...

In this paper, we consider Kasner space-time describing anisotropic three-dimensional expansion of the fluid and obtain dissipative evolution equations for shear stress tensor energy density from kinetic theory. For this, use iterative solution relativistic Boltzmann equation with relaxation time approximation. We show that our results second- third-order reduce to those one-dimensional case un...
