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…
The Role of dimensionality in the stability of a confined Bose gas
Luca Salasnich
We study analytically the ground-state stability of a Bose-Einstein condensate (BEC) confined in an harmonic trap with repulsive or attractive zero-range interaction by minimizing…
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…
On the Convergence of the WKB Series for the Angular Momentum Operator
Luca Salasnich, Fabio Sattin
In this paper we prove a recent conjecture [Robnik M and Salasnich L 1997 J. Phys. A: Math. Gen. 30 1719] about the convergence of the WKB series for the angular momentum operator.…
SWKB for the Angular Momentum
Luca Salasnich, Fabio Sattin
In this paper we solve the eigenvalue problem of the angular momentum operator by using the supersymmetric semiclassical quantum mechanics (SWKB), and show that it gives the correc…
Quantum Signature of the Chaos-Order Transition in a Homogeneous SU(2) Yang-Mills-Higgs System
Luca Salasnich
We analyze a spatially homogeneous SU(2) Yang-Mills-Higgs system both in classical and quantum mechanics. By using the Toda criterion of the Gaussian curvature we find a classical…
Quantum Transition from Order to Chaos in the Nuclear Shell Model
Luca Salasnich
We discuss the role of quantum chaos in atomic nuclei. After reviewing the basic assumptions of the nuclear shell model, we analyze the spectral statistics of the energy levels obt…
Convergence of the Splitting Method for Shallow Water Equations
Maria Morandi Cecchi, Luca Salasnich
In this paper we analyze the convergence of the splitting method for shallow water equations. In particular, we give an analytical estimation of the time step which is necessary fo…
New Results on Quantum Chaos in Atomic Nuclei
V. R. Manfredi, L. Salasnich
In atomic nuclei, ordered and chaotic states generally coexist. In this paper the transition from ordered to chaotic states will be discussed in the framework of roto-vibrational a…
A Note on the Toda Criterion for Interacting Dipole-Quadrupole Vibrations
V. R. Manfredi, L. Salasnich
The Toda criterion of the Gaussian curvature is applied to calculate analytically the transition energy from regular to chaotic motion in a schematic model describing the interacti…
Quantum Chaos in a Yang-Mills-Higgs System
Luca Salasnich
We study the energy fluctuations of a spatially homogeneous SU(2) Yang-Mills-Higgs system. In particular, we analyze the nearest-neighbour spacing distribution which shows a Wigner…
Coexistence of Ordered and Chaotic States in Nuclear Structure
V. R. Manfredi, L. Salasnich
In atomic nuclei, as in other many-body systems, the classical phase space is mixed, so ordered and chaotic states generally coexist. In this contribution we discuss some models, s…
On the Torus Quantization of Two Anyons with Coulomb Interaction in a Magnetic Field
Luca Salasnich
We study two anyons with Coulomb interaction in a uniform magnetic field . By using the torus quantization we obtain the modified Landau and Zeeman formulas for the two anyons.…
Spectral Distribution Studies of fp shell nuclei with modified Kuo--Brown Interaction
K. Kar, S. Sarkar, J. M. G. Gomez +2
The structure of nuclei in the lower half of fp shell is investigated by the spectral distribution method using the modified Kuo-Brown interaction. This interaction recently showed…
