High-Resolution Scanning Tunneling Spectroscopy of Vortex Cores in Inhomogeneous Electronic States of Bi2Sr2CaCu2Ox
Shunsuke Yoshizawa, Taiji Koseki, Ken Matsuba +3
We studied electronic states in vortex cores of slightly overdoped Bi2Sr2CaCu2Ox by scanning tunneling spectroscopy. We have found that they have stripe structures with a 4a0 width…
Quantum limiting behaviors of a vortex core in an anisotropic gap superconductor
S. Kaneko, K. Matsuba, M. Hafiz +8
Quantized bound states at a vortex core are discretized in YNiBC. By using scanning tunneling spectroscopy with an unprecedented 0.1 nm spatial resolution, we find and iden…
Anti-phase Modulation of Electron- and Hole-like States in Vortex Core of Bi2Sr2CaCu2Ox Probed by Scanning Tunneling Spectroscopy
Ken Matsuba, Shunsuke Yoshizawa, Yugo Mochizuki +3
In the vortex core of slightly overdoped Bi2Sr2CaCu2Ox, the electron-like and hole-like states have been found to exhibit spatial modulations in anti-phase with each other along th…
Derivation of Amplitude Equations by Renormalization Group Method
Ken-ichi Matsuba, Kazuhiro Nozaki
A proper formulation in the perturbative renormalization group method is presented to deduce amplitude equations. The formulation makes it possible not only avoiding a serious diff…
Renormalization Group Method and Reductive Perturbation Method
Ken-ichi Matsuba, Kazuhiro Nozaki
It is shown that the renormalization group method does not necessarily eliminate all secular terms in perturbation series to partial differential equations and a functional subspac…
Nonlinear Modulation of Travelling Rolls in Magnetoconvection
Ken-ichi Matsuba, Kenji Imai, Kazuhiro Nozaki
Modulational dynamics of oscillatory travelling rolls in magnetoconvection is studied near the onset of a Hopf bifurcation. Using weakly nonlinear analysis, we derive an envelope e…
