Two-dimensional superconducting diode effect in topological insulator/superconductor heterostructure
Soma Nagahama, Yuki Sato, Minoru Kawamura +7
The superconducting diode effect (SDE) is characterized by the nonreciprocity of Cooper-pair motion with respect to current direction. In three-dimensional (3D) materials, SDE resu…
Quantum geometry in low-energy linear and nonlinear optical responses of magnetic Rashba semiconductor (Ge,Mn)Te
Tsubasa Takagi, Hikaru Watanabe, Ryutaro Yoshimi +7
Quantum geometry appears as a key factor in understanding the optical properties of quantum materials, with the anticipation on diverging or quantized responses near the Dirac and…
Control of nonreciprocal charge transport in topological insulator/superconductor heterostructures with Fermi level tuning and superconducting-layer thickness
Soma Nagahama, Yuki Sato, Minoru Kawamura +7
Nonreciprocal charge transport (NCT) is defined as a phenomenon where electrical resistance depends on the current direction. It has been drawing much attention because it sensitiv…
AC Current-Driven Magnetization Switching and Nonlinear Hall Rectification in a Magnetic Topological Insulator
Yuto Kiyonaga, Masataka Mogi, Ryutaro Yoshimi +7
Spin-orbit torque arising from the spin-orbit-coupled surface states of topological insulators enables current-induced control of magnetization with high efficiency. Here, alternat…
Non-Fermi liquid transport and strong mass enhancement near the nematic quantum critical point in FeSeTe thin films
Yuki Sato, Soma Nagahama, Ilya Belopolski +10
Unconventional superconductivity is often accompanied by non-Fermi liquid (NFL) behavior, which emerges near a quantum critical point (QCP) - a point where an electronic ordered ph…
Charge sensing of few-electron ZnO double quantum dots probed by radio-frequency reflectometry
Kosuke Noro, Motoya Shinozaki, Yusuke Kozuka +6
Zinc oxide (ZnO) has garnered much attention as a promising material for quantum devices due to its unique characteristics. To utilize the potential of ZnO for quantum devices, the…
