Generalized canonical approach to gyrokinetic theory
نویسنده
چکیده
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 electromagnetic field. The customary approach to gyrokinetic theory, using canonical variables or identifying them “a posteriori” by means of Darboux theorem, leads to potential complications and ambiguities due to the fact that canonical coordinates are field-related. Here we propose an innovative formulation to construct gyrokinetic canonical variables based on the introduction of a new definition of canonical transformation. The new approach permits to shed light on this often controversial issue. PACS 45.20 Jj; 52.30 Gz Typeset using REVTEX [email protected] [email protected]

Canonical Lie-transform method in Hamiltonian gyrokinetics: a new approach
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 magnetic field. Although a variety of approaches have been formulated in the past to this well known problem, surprisingly a purely canonical approach based on Lie transform methods is still missing. This paper aims t...
متن کاملGyrokinetic turbulence simulations with kinetic electrons*
Gyrokinetic turbulence simulations are presented with full drift-kinetic electron dynamics including both trapped and passing particle effects. This is made possible by using a generalization of the split-weight scheme �I. Manuilskiy and W. W. Lee, Phys. Plasmas 7, 1381 �2000�� that allows for a variable adiabatic part, as well as use of the parallel canonical momentum formulation. Linear simul...
متن کاملCanonical thermostatics of ideal gas in the frame work of generalized uncertainty principle
The statistical consequences of minimal length supposition are investigated for a canonical ensemble of ideal gas. These effects are encoded in the so-called Generalized Uncertainty Principle (GUP) of the second order. In the frame work of the considered GUP scenario, a unique partition function is obtained by using of two different methods of quantum and classical approaches. It should be noti...

متن کاملA NEW FUZZY MORPHOLOGY APPROACH BASED ON THE FUZZY-VALUED GENERALIZED DEMPSTER-SHAFER THEORY
In this paper, a new Fuzzy Morphology (FM) based on the GeneralizedDempster-Shafer Theory (GDST) is proposed. At first, in order to clarify the similarity ofdefinitions between Mathematical Morphology (MM) and Dempster-Shafer Theory (DST),dilation and erosion morphological operations are studied from a different viewpoint. Then,based on this similarity, a FM based on the GDST is proposed. Unlik...
