Articles Cited by Co-authors. AB 9AA It is known that a plasma in a magnetic field, conceived microscopically as a system of point charges, can exist in a magnetized state, and thus remain confined, inasmuch as it is in an ordered state … More.

We interpret this fact as indicating that some essential qualitative feature is lacking in all models which consider, as the present one, only short-range repulsive potentials and unretarded long-range electric forces. The following articles are merged in Scholar. It is usually assumed, in classical statistical mechanics, that the temperature should coincide, apart from a suitable constant factor, with the mean kinetic energy of the particles.
Rigorous estimates for the series expansions of Hamiltonian perturbation theory A Giorgilli, L Galgani Celestial mechanics 37 2, A partire da esse vengono quindi scritte le equazioni del moto nel modello hamiltoniano. L’ equazione del moto nello spazio degli stati sono le equazioni di Eulero-Lagrange:. Estratto da ” https: The second objective concerns whether it is possible in a microscopic model to obtain normal mode frequencies, or peak frequencies in the optical spectra, that are in good agreement with the experimental data for quartz.

On the other hand, they play an essential role in introducing a chaoticity which involves a definite normal mode. Vedi le condizioni d’uso per i darati.
