Relativistic kinetic theory of magnetoplasmas
Alexei Beklemishev, Piero Nicolini, Massimo Tessarotto
Recently, an increasing interest in astrophysical as well as laboratory plasmas has been manifested in reference to the existence of relativistic flows, related in turn to the prod…
Canonical Lie-transform method in Hamiltonian gyrokinetics: a new approach
Piero Nicolini, Massimo Tessarotto
The well-known gyrokinetic problem regards the perturbative expansion related to the dynamics of a charged particle subject to fast gyration motion due to the presence of a strong…
Theory of stochastic transitions in area preserving maps
Piero Nicolini, Massimo Tessarotto
A famous aspect of discrete dynamical systems defined by area-preserving maps is the physical interpretation of stochastic transitions occurring locally which manifest themselves t…
Generalized canonical approach to gyrokinetic theory
Piero Nicolini, Massimo Tessarotto
We face the well-known gyrokinetic problem, which arises in the description of the dynamics of a charged particle subject to fast gyration for the presence of a strong electromagne…
Vacuum energy momentum tensor in (2+1) NC scalar field theory
P. Nicolini
A scalar field in (2+1) dimensional Minkowski space-time is considered. Postulating noncommutative spatial coordinates, one is able to determine the (UV finite) vacuum expectation…
