Transmission coefficient for ballistic transport
through quantum resonator
ABSTRACT. A model for the description of ballistic transport in 1D-2D-1D
system based on the theory of self-adjoint extensions of
symmetric operators is suggested. Formula for transmission
coefficient for the system, particurlarly, in the case of presense
of a magnetic field, is obtained.
