Tunable tunnel coupling in a double quantum antidot with cotunneling via localized state
Tokuro Hata, Kazuhiro Sada, Tomoki Uchino +4
Controlling tunnel coupling between quantum antidots (QADs) in the quantum Hall (QH) regime is problematic. We propose and demonstrate a scheme for tunable tunnel coupling between…
Non-thermal Tomonaga-Luttinger liquid eventually emerging from hot electrons in the quantum Hall regime
Kotaro Suzuki, Tokuro Hata, Yuya Sato +3
Dynamics of integrable systems, such as Tomonaga-Luttinger (TL) liquids, is deterministic, and the absence of stochastic thermalization processes provides unique characteristics, s…
Gate-tunable giant superconducting nonreciprocal transport in few-layer -MoTe
T. Wakamura, M. Hashisaka, S. Hoshino +7
We demonstrate gate-tunable giant field-dependent nonreciprocal transport (magnetochiral anisotropy) in a noncentrosymmetric superconductor -MoTe in the thin limit.…
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…
Time-resolved measurement of ambipolar edge magnetoplasmon transport in InAs/InGaSb composite quantum wells
Hiroshi Kamata, Hiroshi Irie, Norio Kumada +1
Time-resolved charge transport measurement for one-dimensional edge states is a powerful means for investigating nonequilibrium charge dynamics and underlying interaction effects t…
