Unstable particles in non-relativistic quantum mechanics?
H. Hernandez-Coronado
The Schroedinger equation is up-to-a-phase invariant under the Galilei group. This phase leads to the Bargmann's superselection rule, which forbids the existence of the superpositi…

Perfect transmission scattering as a PT-symmetric spectral problem
H. Hernandez-Coronado, D. Krejcirik, P. Siegl
We establish that a perfect-transmission scattering problem can be described by a class of parity and time reversal symmetric operators and hereby we provide a scenario for underst…
