Mach-Zehnder interference of fractionalized electron-spin excitations
Takase Shimizu, Eiki Iyoda, Satoshi Sasaki +4
Inter-channel Coulomb interaction mixes charge excitations in copropagating quantum Hall edge channels, generating coupled excitation eigenmodes propagating at different speeds. Th…
Simultaneous measurement of specific heat and thermal conductivity in pulsed magnetic fields
Tetsuya Nomoto, Chengchao Zhong, Hiroshi Kageyama +10
We report an experimental setup for simultaneously measuring specific heat and thermal conductivity in feedback-controlled pulsed magnetic fields of 50 msec duration at cryogenic t…
Half-mirror for electrons on quantum Hall copropagating edge channels
Takase Shimizu, Jun-ichiro Ohe, Akira Endo +2
A half-mirror that divides a spin-polarized electron into two parallel copropagating spin-resolved quantum Hall edge channels one half each is presented in this study. The partitio…
Anisotropic Behavior of the Thermoelectric Power and the Thermal Conductivity in a Unidirectional Lateral Superlattice: A Typical Anisotropic System Exhibiting Two Distinct Nernst Coefficients
Akira Endo, Shingo Katsumoto, Yasuhiro Iye
We have calculated the thermoelectric conductivity tensor and the thermal conductivity tensor of a unidirectional lateral superlattice (ULSL) ($i,j = x,…
Joule heating and the thermal conductivity of a two-dimensional electron gas at cryogenic temperatures studied by modified 3 method
Akira Endo, Shingo Katsumoto, Yasuhiro Iye
During the standard ac lock-in measurement of the resistance of a two-dimensional electron gas (2DEG) applying an ac current , the electron temperature $…
Commensurability oscillations in the Hall resistance of unidirectional lateral superlattices
Akira Endo, Shingo Katsumoto, Yasuhiro Iye
We have observed commensurability oscillations (CO) in the Hall resistance of a unidirectional lateral superlattice (ULSL). The CO, having small amplitudes ( 1 )…
