Solvable simulation of a double-well problem in PT-symmetric quantum mechanics
Original language description
Within the framework of PT-symmetric quantum mechanics of bound states (which works with parity-pseudo-Hermitian Hamiltonians H = (PHP)-P-inverted iota and real spectra) we mimic some effects of the double-well structure of potentials by a pair of deltafunctions with mutually complex conjugate strengths. The model is solvable by the standard matching technique and exhibits several interesting features. We observe an amazingly robust absence of any PT-symmetry breaking. A quasi-degeneracy which occurs in the high-energy domain is interpreted as a manifestation of certain 'quantum beats'

Czech description
Potenciál ve formě dvojice delta funkcí vykazuje robustní realitu spektra, očekávanou kvazi-degeneraci a neočekávaný fenomén vzniku "kvantových rázů".
