Alternative descriptions and bipartite compound quantum systems
G. Scolarici, L. Solombrino
We analyze some features of alternative Hermitian and quasi-Hermitian quantum descriptions of simple and bipartite compound systems. We show that alternative descriptions of two in…
Quasistationary quaternionic Hamiltonians and complex stochastic maps
G. Scolarici, L. Solombrino
We show that the complex projections of time-dependent -quasianti-Hermitian quaternionic Hamiltonian dynamics are complex stochastic dynamics in the space of complex quasi-Hermi…
Alternative Descriptions in Quaternionic Quantum Mechanics
A. Blasi, G. Scolarici, L. Solombrino
We characterize the quasianti-Hermitian quaternionic operators in QQM by means of their spectra; moreover, we state a necessary and sufficient condition for a set of quasianti-Herm…
Pseudo-Hermitian Hamiltonians, indefinite inner product spaces and their symmetries
A. Blasi, G. Scolarici, L. Solombrino
We extend the definition of generalized parity , charge-conjugation and time-reversal operators to nondiagonalizable pseudo-Hermitian Hamiltonians, and we use these gene…
On the pseudo-Hermitian nondiagonalizable Hamiltonians
G. Scolarici, L. Solombrino
We consider a class of (possibly nondiagonalizable) pseudo-Hermitian operators with discrete spectrum, showing that in no case (unless they are diagonalizable and have a real spect…
Pseudohermitian Hamiltonians, time-reversal invariance and Kramers degeneracy
G. Scolarici, L. Solombrino
A necessary and sufficient condition in order that a (diagonalizable) pseudohermitian operator admits an antilinear symmetry T such that T^{2}=-1 is proven. This result can be used…
Weak pseudo-Hermiticity and antilinear commutant
L. Solombrino
We inquire into some properties of diagonalizable pseudo-Hermitian operators, showing that their definition can be relaxed and that the pseudo-Hermiticity property is strictly conn…
