Phantom universe from CPT symmetric QFT
Alexander A. Andrianov, Francesco Cannata, Alexander Y. Kamenshchik
Inspired by the generalization of quantum theory for the case of non-Hermitian Hamiltonians with CPT symmetry, we construct a simple classical cosmological scalar field based model…
Smooth dynamical (de)-phantomization of a scalar field in simple cosmological models
Alexander A. Andrianov, Francesco Cannata, Alexander Y. Kamenshchik
Simple scalar field cosmological models are considered describing gravity assisted crossing of the phantom divide line. This crossing or (de)-phantomization characterized by the ch…
Double Shape Invariance of Two-Dimensional Singular Morse Model
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
A second shape invariance property of the two-dimensional generalized Morse potential is discovered. Though the potential is not amenable to conventional separation of variables, t…
