Three-Dimensional Shape Invariant Non-Separable Model With Equidistant Spectrum

M. S. Bardavelidze, F. Cannata, M. V. Ioffe +1

A class of three-dimensional models which satisfy supersymmetric intertwining relations with the simplest - oscillator-like - variant of shape invariance is constructed. It is prov…

Equidistance of the Complex 2-Dim Anharmonic Oscillator Spectrum: Exact Solution

F. Cannata, M. V. Ioffe, D. N. Nishnianidze

We study a class of quantum two-dimensional models with complex potentials of specific form. They can be considered as the generalization of a recently studied model with quadratic…

Remarks on the general solution for the flat Friedman universe with exponential scalar-field potential and dust

A. A. Andrianov, F. Cannata, A. Y. Kamenshchik

We show that the simple extension of the method of obtaining the general exact solution for the cosmological model with the exponential scalar-field potential to the case when the…

General solution of scalar field cosmology with a (piecewise) exponential potential

A. A. Andrianov, F. Cannata, A. Yu. Kamenshchik

We study in detail the general solution for a scalar field cosmology with an exponential potential, correcting some imprecisions, encountered previously in the literature. In addit…

New Two-Dimensional Quantum Models with Shape Invariance

F. Cannata, M. V. Ioffe, D. N. Nishnianidze

Two-dimensional quantum models which obey the property of shape invariance are built in the framework of polynomial two-dimensional SUSY Quantum Mechanics. They are obtained using…

Reflectionless PT-symmetric potentials in the one-dimensional Dirac equation

Francesco Cannata, Alberto Ventura

We study the one-dimensional Dirac equation with local PT-symmetric potentials whose discrete eigenfunctions and continuum asymptotic eigenfunctions are eigenfunctions of the PT op…
