Coherent-Incoherent Crossover of Charge and Neutral Mode Transport as Evidence for the Disorder-Dominated Fractional Edge Phase
Masayuki Hashisaka, Takuya Ito, Takafumi Akiho +4
Couplings between topological edge channels open electronic phases possessing nontrivial eigenmodes far beyond the noninteracting-edge picture. However, inelastic scatterings mask…
Fast time-domain current measurement for quantum dot charge sensing using a homemade cryogenic transimpedance amplifier
Heorhii Bohuslavskyi, Masayuki Hashisaka, Takase Shimizu +3
We developed a high-speed and low-noise time-domain current measurement scheme using a homemade GaAs high-electron-mobility-transistor-based cryogenic transimpedance amplifier (TIA…
Non-uniform heat redistribution among multiple channels in the integer quantum Hall regime
Ryota Konuma, Chaojing Lin, Tokuro Hata +4
Heat transport in multiple quantum-Hall edge channels at Landau-level filling factor nu = 2, 4, and 8 is investigated with a quantum point contact as a heat generator and a quantum…
Impact of in-situ controlled disorder screening on fractional quantum Hall effects and composite-fermion transport
T. Akiho, K. Muraki
We examine the impact of random potential due to remote impurites (RIs) and its in-situ controlled screening on fractional quantum Hall effects (FQHEs) around Landau-level filling…
