Efficient heat-energy conversion from a non-thermal Tomonaga-Luttinger liquid
Hikaru Yamazaki, Masashi Uemura, Haruhi Tanaka +5
Energy harvesting is a technique that generates useful work from waste heat. Conventional energy harvesters acting on local thermal equilibrium states are constrained by thermodyna…
Coulomb oscillations of a quantum antidot formed by an airbridged pillar gate in the integer and fractional quantum Hall regime
Tokuro Hata, Hiroki Mitani, Hidetaka Uchiyama +3
Quantum antidots (QAD) are attractive for manipulating quasiparticles in quantum Hall (QH) systems. Here, we form a QAD in the integer and fractional QH regimes at nominal Landau-l…
Static quantum dot on a potential hilltop for generating and analyzing hot electrons in the quantum Hall regime
Ryo Oishi, Yuto Hongu, Tokuro Hata +4
We propose and demonstrate a static quantum dot on a potential hilltop to generate and analyze ballistic hot electrons along a quantum Hall edge channel well above the chemical pot…
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…
Kondo Temperature Evaluated from Linear Conductance in Magnetic Fields
Rui Sakano, Tokuro Hata, Kaiji Motoyama +8
We theoretically and experimentally study the universal scaling property of the spin-1/2 Kondo state in the magnetic field dependence of bias-voltage linear conductance through a q…
