Spectroscopic study on hot-electron transport in a quantum Hall edge channel
Tomoaki Ota, Shunya Akiyama, Masayuki Hashisaka +2
Hot electron transport in a quantum Hall edge channel of an AlGaAs/GaAs heterostructure is studied by investigating the energy distribution function in the channel. Ballistic hot-e…
Signatures of a non-thermal metastable state in copropagating quantum Hall edge channels
Kosuke Itoh, Ryo Nakazawa, Tomoaki Ota +3
A Tomonaga-Luttinger (TL) liquid is known as an integrable system, in which a non-equilibrium many-body state survives without relaxing to a thermalized state. This intriguing char…
Shot-noise evidence of fractional quasiparticle creation in a local fractional quantum Hall state
Masayuki Hashisaka, Tomoaki Ota, Koji Muraki +1
We have experimentally identified fractional quasiparticle creation in a tunneling process through a local fractional quantum Hall (FQH) state. The local FQH state is prepared in a…
