Highly confined two-dimensional electron gas in an In 0.52 Al 0.48 As/In 0.53 Ga 0.47 As modulation-doped structure with a strained InAs quantum well
TL;DR: In this paper, the effective mass of two-dimensional electron gas (2DEG) in an In0.52Al0.48As/In0.53Ga0.47As modulation-doped (MD) structure with an InAs quantum well inserted into the InGaAs channel (InAs-inserted channel).
Journal ArticleDOI
Multicomponent order parameter superconductivity of Sr 2 RuO 4 revealed by topological junctions
Muhammad Anwar,Ryosuke Ishiguro,Ryosuke Ishiguro,Terutaro Nakamura,Terutaro Nakamura,M. Yakabe,Shingo Yonezawa,Hideaki Takayanagi,Y. Maeno +8 more
TL;DR: In this paper, the authors investigated the dynamic behavior of a topological junction, where a superconductor is surrounded by another super-conductor, in which the difference in phase winding between the $s$-wave superconductivity in Ru micro-islands induced from Nb and the superconductivities of Sr$_2$RuO$_4$ mainly governs the junction behavior.
Journal ArticleDOI
Tunable Exchange Interaction in Quantum Dot Devices
TL;DR: In this article, the authors theoretically discuss the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between semiconductor quantum dots (QDs) and estimate the magnitude of RKKY interaction in QDs as a function of the electron density and the inter-dot distance.
Journal ArticleDOI
Coherent control of a flux qubit by phase-shifted resonant microwave pulses
TL;DR: In this paper, the quantum state of a flux qubit was successfully pulse controlled by using a resonant microwave without introducing detuning, and the qubit Larmor precession was observed stroboscopically with an angular velocity of 2π×11.4Grad∕s.
