[Tu-A1-E-03 (Invited)]Coherent dynamics of copropagating integer quantum Hall edge states

〇Masayuki Hashisaka1 (1. The Univ. of Tokyo (Japan))
We investigate coherent electron fractionalization in copropagating integer quantum Hall edge channels using a Mach–Zehnder interferometer. Observed visibility oscillations reveal second-order interference between fractionalized spin excitations, demonstrating the electron coherence through the fractionalization process.
