Synthesizing resistance plateau at the first Landau level confined in a quantum point contact

M. H. Fauzi, K. Nakagawara, K. Hashimoto +2

A comprehensive understanding of quantum Hall edge transmission, especially the hole-conjugate of a Laughlin state such as a state, is critical for advancing fundamental quan…

NMR Evidence for Spin Canting in a Bilayer nu = 2 Quantum Hall System

N. Kumada, K. Muraki, Y. Hirayama

We investigate the electron spin states in the bilayer quantum Hall system at total Landau level filling factor nu =2 exploiting current-pumped and resistively detected NMR. The me…

Realization of Strong Coupling Fixed Point in Multilevel Kondo Models

Kazumasa Hattori, Yosuke Hirayama, Kazumasa Miyake

Impurity four- and six-level Kondo model, in which an ion is tunneling among four- and six-stable points and interacting with surrounding conduction electrons, are investigated by…

Local Heavy Quasiparticle in Four-Level Kondo Model

Kazumasa Hattori, Yosuke Hirayama, Kazumasa Miyake

An impurity four-level Kondo model, in which an ion is tunneling among 4-stable points and interacting with surrounding conduction electrons, is investigated using both perturbativ…

Spin Degree of Freedom in the nu =1 Bilayer Electron System Investigated via Nuclear Spin Relaxation

N. Kumada, K. Muraki, K. Hashimoto +1

The nuclear-spin-relaxation rate 1/T_1 has been measured in a bilayer electron system at and around total Landau level filling factor nu =1. The measured 1/T_1, which probes electr…
