Title:
Bulk-edge correspondence at the spin-to-integer quantum Hall effect
crossover in topological superconductors
Speaker:
Igor Burmistrov (HSE University)
Abstract:
The spin and integer quantum Hall effects are two cousins of topological
phase transitions in two-dimensional electronic systems. Their close
relationship makes it possible to transform spin to integer quantum Hall
effect in two-dimensional topological superconductors by continuous
increase in a symmetry breaking Zeeman magnetic field. We study
peculiarities of bulk-edge correspondence and a fate of massless edge
and bulk topological (instantons) excitations at such the crossover.
