Chaotic Oscillations in Finite Quantum Systems: Trapped Bose-Einstein Condensates
Luca Salasnich
We discuss the recently achieved Bose-Einstein condensation for alkali-metal atoms in magnetic traps. The theoretically predicted low-energy collective oscillations of the condensa…
Different Facets of Chaos in Quantum Mechanics
V. R. Manfredi, L. Salasnich
Nowadays there is no universally accepted definition of quantum chaos. In this paper we review and critically discuss different approaches to the subject, such as Quantum Chaology…
Chaos in coplanar classical collisions with particles interacting through forces
F. Sattin, L. Salasnich
The scattering among three particles interacting through forces, with opposite charges and widely different masses, is studied in a coplanar geometry. The present work show…
Turbulence and Bifurcation in the Motion of an Hydrocyclone
Maria Morandi Cecchi, Luca Salasnich
The hydrocyclone is a tool used in different fields but mostly in mining industries to separate minerals. The minerals are put in a liquid or in a stable suspension of a chosen den…
Review on 'Integrability of the S-Matrix vs Integrability of the Hamiltonian' by C. Jung and T.H. Seligman
Luca Salasnich
We review the paper 'Integrability of the S-Matrix vs Integrability of the Hamiltonian' by C. Jung and T.H. Seligman (Phys. Rep. 285, 77-141 (1997)). This paper deals with the conn…
WKB corrections to the energy splitting in double-well potentials
Marko Robnik, Luca Salasnich
By using the WKB quantization we deduce an analytical formula for the energy splitting in a double-well potential which is the usual Landau formula with additional quantum correcti…
Chaotic features in classical scattering processes between ions and atoms
Fabio Sattin, Luca Salasnich
A numerical study has been done of collisions between protons and hydrogen atoms, treated as classical particles, at low impact velocities. The presence of chaos has been looked fo…
WKB to all orders and accuracy of the semiclassical quantization
Marko Robnik, Luca Salasnich
We perform a systematic WKB expansion to all orders for a one--dimensional system with potential . We are able to sum the series to the exact energy spectrum…
Non--Hyperbolic Dynamics: a Family of Special Functions
Maria Morandi Cecchi, Luca Salasnich
In this paper we present some theorems for a class of non--hyperbolic fixed points on and then analyze a family of functions on the plane which have a non--hyperb…
WKB expansion for the angular momentum and the Kepler problem: from the torus quantization to the exact one
Marko Robnik, Luca Salasnich
We calculate the WKB series for the angular momentum and the non--relativistic 3-dim Kepler problem. This is the first semiclassical treatment of the angular momentum for terms bey…
Quantum corrections to the semiclassical quantization of a nonintegrable system
Luca Salasnich, Marko Robnik
We study the semiclassical behaviour of a two--dimensional nonintegrable system. In particular we analyze the question of quantum corrections to the semiclassical quantization obta…
