Reconstruction of scalar potentials in two-field cosmological models
Alexander A. Andrianov, Francesco Cannata, Alexander Y. Kamenshchik +1
We study the procedure of the reconstruction of phantom-scalar field potentials in two-field cosmological models. It is shown that while in the one-field case the chosen cosmologic…
Overcritical PT-symmetric square well potential in the Dirac equation
Francesco Cannata, Alberto Ventura
We study scattering properties of a PT-symmetric square well potential with real depth larger than the threshold of particle-antiparticle pair production as the time component of a…
Pseudo-Hermiticity of an Exactly Solvable Two-Dimensional Model
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
We study a two-dimensional exactly solvable non-Hermitian non-symmetric quantum model with real spectrum, which is not amenable to separation of variables, by supersymmetrical…
