On the Landau-Teller approximation for energy exchanges with fast degrees of freedom / G. Benettin, A. Carati, P. Sempio. - In: JOURNAL OF STATISTICAL PHYSICS. - ISSN 0022-4715. - 73:1-2(1993), pp. 175-192.
Abstract:
We revisit the Landau-Teller heuristic approach to adiabatic invariants and, following Rapp, use it to investigate the energy exchanges between the different degrees of freedom, in simple Hamiltonian systems describing the collision of fast rotating or vibrating molecules with a fixed wall. We critically compare the theoretical results with particularly accurate numerical computations (quite small energy exchanges, namely of one part over 1030, are measured).
