PT-symmetry breaking in resonant tunneling heterostructures
A. A. Gorbatsevich, N. M. Shubin
We present fermionic model based on symmetric resonant tunneling heterostructure, which demonstrates spontaneous symmetry breaking in respect to combined operations of space invers…

Interface electronic states and boundary conditions for envelope functions
I. V. Tokatly, A. G. Tsibizov, A. A. Gorbatsevich
The envelope-function method with generalized boundary conditions is applied to the description of localized and resonant interface states. A complete set of phenomenological condi…
