The PT-symmetric brachistochrone problem, Lorentz boosts and non-unitary operator equivalence classes
Uwe Guenther, Boris F. Samsonov
The PT-symmetric (PTS) quantum brachistochrone problem is reanalyzed as quantum system consisting of a non-Hermitian PTS component and a purely Hermitian component simultaneously.…
The spherically symmetric alpha2-dynamo and some of its spectral peculiarities
Uwe Guenther, Oleg N. Kirillov, Boris F. Samsonov +1
A brief overview is given over recent results on the spectral properties of spherically symmetric MHD alpha2-dynamos. In particular, the spectra of sphere-confined fluid or plasma…
Exact propagators for SUSY partners
Andrey M. Pupasov, Boris F. Samsonov, Uwe Guenther
Pairs of SUSY partner Hamiltonians are studied which are interrelated by usual (linear) or polynomial supersymmetry. Assuming the model of one of the Hamiltonians as exactly solvab…
