THE FLOQUET METHOD FOR PT-SYMMETRIC PERIODIC POTENTIALS
Author: Jones F., H.
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)By the general theory of PT-symmetric quantum systems, their energy levels are either real or occur in complex-conjugate pairs, which implies that the secular equation must be real. However, for periodic potentials it is ...
