Real-Time Decoherence of Landau and Levitov Quasiparticles in Quantum Hall Edge Channels
Real-Time Decoherence of Landau and Levitov Quasiparticles in Quantum Hall Edge Channels
Quantum Hall edge channels at integer filling factor provide a unique test bench to understand the decoherence and relaxation of single-electron excitations in a ballistic quantum conductor. In this Letter, we obtain a full visualization of the decoherence scenario of energy (Landau)- and time (Levitov)-resolved single-electron excitations at filling factor …
