Meccanica hamiltoniana – Wikipedia

Estratto da gaalgani https: Giancarlo Benettin Verified email at math. Disambiguazione — Se stai cercando altri significati di Hamiltoniana, vedi Hamiltoniano. La meccanica hamiltoniana, interessandosi di oggetti in moto, rientra nell’ambito dell’ analisi dei sistemi dinamicicon la quale condivide il formalismo matematico. Lyapunov characteristic exponents for smooth dynamical systems and for Hamiltonian systems: This paper is a continuation of a recent one in which, apparently for the first time, the existence of polaritons in ionic crystals was proven in a microscopic electrodynamic theory.

It is an old result of Bohr that, according to classical statistical mechanics, at equilibrium a system of electrons in a static magnetic field presents no magnetization.

Si tratta delle coordinate nello “spazio degli stati” del sistema dinamico costituito dal punto in moto:. Journal of statistical physics 78, 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.

A partire da esse vengono quindi scritte le equazioni del moto nel modello hamiltoniano. Vedi le condizioni d’uso per i dettagli. On the other hand, they play an essential role in introducing a chaoticity which involves a definite normal mode.

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.
