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…
Charge equilibration in integer and fractional quantum Hall edge channels in a generalized Hall-bar device
Chaojing Lin, Ryota Eguchi, Masayuki Hashisaka +3
Charge equilibration between quantum-Hall edge states can be studied to reveal geometric structure of edge channels not only in the integer quantum Hall (IQH) regime but also in th…
Plasmon modes of coupled quantum Hall edge channels in the presence of disorder-induced tunneling
Toshimasa Fujisawa, Chaojing Lin
Coupled quantum Hall edge channels show intriguing non-trivial modes, for example, charge and neutral modes at Landau level filling factors 2 and 2/3. We propose an appropriate and…
Dispersive detection of a charge qubit with a broadband high-impedance quantum-Hall plasmon resonator
Chaojing Lin, Kosei Teshima, Takafumi Akiho +2
Cavity quantum electrodynamics (cQED) provides strong light-matter interactions that can be used for manipulating and detecting quantum states. The interaction can be enhanced by i…
Spin correlations and colossal magnetoresistance in HgCrSe
Chaojing Lin, Changjiang Yi, Youguo Shi +4
This study aims to unravel the mechanism of colossal magnetoresistance (CMR) observed in n-type HgCrSe, in which low-density conduction electrons are exchange-coupled to a…
Unconventional temperature dependence of the anomalous Hall effect in HgCr2Se4
Shuai Yang, Zhilin Li, Chaojing Lin +4
At sufficiently low temperatures, many quantum effects, such as weak localization, electron-electron interaction (EEI), and Kondo screening, can lead to pronounced corrections to t…
