"Supercomputer modeling of semiconductor quantum nanosystems" Tkachenko O.A., Tkachenko V.A. 
Numerical research of electron transport and quantum effects in nanostructures often requires solving a number of large problems dependent on external parameters like temperature, magnetic field, chemical potential, or applied voltage. When a problem fits computing capability of a single node, these calculations are naturally parallel. Taking into account the realistic geometry of structures or electronelectron interaction allowed us to find new physical effects: redirection of the ballistic electron flow in the Ybranch, fluctuations of phase and temperature dependence of AharonovBohm oscillations in the ring interferometer, 0.7feature of conductance in the quantum point contact, formation of fractal terrases of voltage distribution, and point ohmic heating in disordered antidot lattice. Keywords: numerical modeling, nanostructures, twodimensional electron gas, Landauer formula, scattering, Schroedinger equation, Poisson equation
