Bimodal pattern in the fragmentation of Au quasi-projectiles
M. Bruno, F. Gulminelli, F. Cannata +3
Signals of bimodality have been investigated in experimental data of quasi-projectile decay produced in Au+Au collisions at 35 AMeV. This same data set was already shown to present…
Non-linear Supersymmetry for non-Hermitian, non-diagonalizable Hamiltonians: I. General properties
A. A. Andrianov, F. Cannata, A. V. Sokolov
We study complex potentials and related non-diagonalizable Hamiltonians with special emphasis on formal definitions of associated functions and Jordan cells. The nonlinear SUSY for…
Scattering in PT-symmetric quantum mechanics
F. Cannata, J. -P. Dedonder, A. Ventura
A general formalism is worked out for the description of one-dimensional scattering in non-hermitian quantum mechanics and constraints on transmission and reflection coefficients a…
Scattering by PT-symmetric non-local potentials
Francesco Cannata, Alberto Ventura
A general formalism is worked out for the description of one-dimensional scattering by non-local separable potentials and constraints on transmission and reflection coefficients ar…
Complex Lagrangians and phantom cosmology
A. A. Andrianov, F. Cannata, A. Y. Kamenshchik
Motivated by the generalization of quantum theory for the case of non-Hermitian Hamiltonians with PT symmetry, we show how a classical cosmological model describes a smooth transit…
Networks of cosmological histories, crossing of the phantom divide line and potentials with cusps
Francesco Cannata, Alexander Y. Kamenshchik
We discuss the phenomenon of the smooth dynamical gravity induced crossing of the phantom divide line in a framework of simple cosmological models where it appears to occur rather…
