Unified theory of resonances and bound states in the continuum in Hermitian tight-binding models
A. A. Gorbatsevich, N. M. Shubin
We study transport properties of an arbitrary two terminal Hermitian system within a tight-binding approximation and derive the expression for the transparency in the form, which e…
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…
Hidden Defect Pairs: Objects Invisible in Low-Energy Electron Scattering
A. A. Gorbatsevich
Objects composed of lattice defects exist within a one-dimensional tight-binding model whose electron reflection coefficient in the low-energy case is equal to zero. Localized stat…
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…
Field-asymmetric transverse magnetoresistance in a nonmagnetic quantum-size structure
A. A. Gorbatsevich, V. V. Kapaev, Yu. V. Kopaev +3
A new phenomenon is observed experimentally in a heavily doped asymmetric quantum-size structure in a magnetic field parallel to the quantum-well layers - a transverse magnetoresis…
Formation of k-space indirect magnetoexcitons in double-quantum-well direct gap heterostructures
A. A. Gorbatsevich, I. V. Tokatly
Spectrum of excitons in double-quantum-well structures is calculated in tilted magnetic field. It is shown that spectrum becomes asymmetric in quasimomentum if a transverse in resp…
