Peltier cooling in Corbino-geometry quantum Hall systems
Akira Endo, Yoshiaki Hashimoto
Quantum Hall systems having Corbino geometry are expected to have a large Peltier coefficient in the quantum Hall plateau region. We present an analytic formula for $Π_{rr…
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…
Gate controlled unitary operation on flying spin qubits in quantum Hall edge states
Takase Shimizu, Taketomo Nakamura, Yoshiaki Hashimoto +2
Spin and orbital freedoms of electrons traveling on spin-resolved quantum Hall edge states (quantum Hall ferromagnets) are maximally entangled. The unitary operations on these two…
Spin triplet superconducting proximity effect in a ferromagnetic semiconductor
Taketomo Nakamura, Le Duc Anh, Yoshiaki Hashimoto +3
Conventional spin-singlet superconductivity that deeply penetrates into ferromagnets is typically killed by the exchange interaction, which destroys the spin-singlet pairs. Under c…
Trembling electrons cause conductance fluctuation
Yu Iwasaki, Yoshiaki Hashimoto, Taketomo Nakamura +1
The highly successful Dirac equation can predict peculiar effects such as Klein tunneling and the "Zitterbewegung" (German for "trembling motion") of electrons. From the time it wa…
Experimental Verification of a Spin-Interference Device Action
Yu Iwasaki, Yoshiaki Hashimoto, Taketomo Nakamura +1
We report the detection of spin interference signal in an Aharonov-Bohm type interferometer with quantum dots on the conduction paths. We have found that resonators like quantum do…
