Time-resolved investigation of plasmon mode along interface channels in integer and fractional quantum Hall regimes
Chaojing Lin, Masayuki Hashisaka, Takafumi Akiho +2
Quantum Hall (QH) edge channels appear not only along the edge of the electron gas but also along an interface between two QH regions with different filling factors. However, the f…
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…
Quantized charge fractionalization at quantum Hall Y junctions in the disorder-dominated regime
Chaojing Lin, Masayuki Hashisaka, Takafumi Akiho +2
Fractionalization is a phenomenon where an elementary excitation partitions into several pieces. This picture explains non-trivial transport through a junction of one-dimensional e…
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…
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…
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…
Observation of Anderson localization in ultrathin films of three-dimensional topological insulators
Jian Liao, Yunbo Ou, Xiao Feng +8
Anderson localization, the absence of diffusive transport in disordered systems, has been manifested as hopping transport in numerous electronic systems, whereas in recently discov…
Evidence for Half-Metallicity in n-type HgCr2Se4
Tong Guan, Chaojing Lin, Chongli Yang +8
High quality HgCrSe single crystals have been investigated by magnetization, electron transport and Andreev reflection spectroscopy. In the ferromagnetic ground state, the…
