Attend a theoretical physics seminar exploring quasiclassical scattering on edge defects of topological insulators in magnetic fields. Examine how edge states of two-dimensional topological insulators scatter from edge defects when subjected to uniform external magnetic fields, where the magnetic field breaks time-reversal symmetry and destroys the topological prohibition on backscattering. Learn how scattering in this problem always represents an above-barrier effect regardless of the edge deformation shape and magnetic field magnitude. Discover the application of the Pokrovsky-Khalatnikov method for analytically obtaining both the exponential and pre-exponential components of scattering amplitude for broad classes of analytical deformation profiles. Explore predictions of quantum oscillations in reflection coefficients as functions of magnetic field for general potential forms, presented by Dr. Yaroslav Rodionov from the Institute of Theoretical and Applied Electrodynamics of RAS at the Abrikosov Center for Theoretical Physics.
