Covariant formulation of spatially non-symmetric kinetic equilibria in magnetized astrophysical plasmas
Claudio Cremaschini, Massimo Tessarotto, Zdeněk Stuchlík
Astrophysical plasmas in the surrounding of compact objects and subject to intense gravitational and electromagnetic fields are believed to give rise to relativistic regimes. Theor…
Polytropic representation of the kinetic pressure tensor of non-ideal magnetized fluids in equilibrium toroidal structures
Claudio Cremaschini, Jiří Kovář, Zdeněk Stuchlík +1
Non-ideal fluids are generally subject to the occurrence of non-isotropic pressure tensors, whose determination is fundamental in order to characterize their dynamical and thermody…
Kinetic description of rotating Tokamak plasmas with anisotropic temperatures in the collisionless regime
Claudio Cremaschini, Massimo Tessarotto
A largely unsolved theoretical issue in controlled fusion research is the consistent \textit{kinetic} treatment of slowly-time varying plasma states occurring in collisionless and…
On the existence of canonical gyrokinetic variables for chaotic magnetic fields
Piero Nicolini, Massimo Tessarotto
The gyrokinetic description of particle dynamics faces a basic difficulty when a special type of canonical variables is sought, i.e., the so-called \textit{gyrokinetic canonical va…
Generalized covariant gyrokinetic dynamics of magnetoplasmas
C. Cremaschini, M. Tessarotto, P. Nicolini +1
A basic prerequisite for the investigation of relativistic astrophysical magnetoplasmas, occurring typically in the vicinity of massive stellar objects (black holes, neutron stars,…
Nonlinear Debye screening in strongly-coupled plasmas
D. Sarmah, M. Tessarotto, M. Salimullah
An ubiquitous property of plasmas is the so-called Debye shielding of the electrostatic potential. Important aspects of Debye screening concern, in particular, the investigation of…
Non-linear gyrokinetic theory of magnetoplasmas
Massimo Tessarotto, Claudio Cremaschini, Piero Nicolini +1
A crucial issue in relativistic plasma, particularly relevant in the astrophysical context, is the description of highly magnetized plasmas based on a covariant formulation of gyro…
Plasma-sheath effects on the Debye screening problem
D. Sarmah, M. Tessarotto, M. Salimullah
The classical Debye-Hückel screening effect of the electrostatic field generated by isolated charged particles immersed in a plasma is reviewed. The validity of the underlying math…
Non-linear charge reduction effect in strongly-coupled plasmas
D. Sarmah, M. Tessarotto, M. Salimullah
The charge reduction effect, produced by the nonlinear Debye screening of high-Z charges occuring in strongly-coupled plasmas, is investigated. An analytic asymptotic expression is…
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…
