Quantum Hall effect in bilayer and multilayer graphenes with finite gate voltage
Masaaki Nakamura, Lila Hirasawa, Ken-Ichiro Imura
We discuss the quantum Hall effect of bilayer graphene with finite gate voltage where the Fermi energy exceeds the interlayer hopping energy. We calculated magnetic susceptibility,…
Numerical study of transport through a single impurity in a spinful Tomonaga-Luttinger liquid
Yuji Hamamoto, Ken-Ichiro Imura, Takeo Kato
The single impurity problem in a spinful Tomonaga-Luttinger liquid is studied numerically using path-integral Monte Carlo methods. The advantage of our approach is that the system…
Characterization of two-dimensional fermionic insulating states
Ryuichi Shindou, Ken-Ichiro Imura, Masao Ogata
Inspired by the duality picture between superconductivity and insulator in two spatial dimension, we conjecture that the order parameter, suitable for characterizing 2D fermionic i…
Full counting statistics for transport through a molecular quantum dot magnet
Ken-Ichiro Imura, Yasuhiro Utsumi, Thierry Martin
Full counting statistics (FCS) for the transport through a molecular quantum dot magnet is studied theoretically in the incoherent tunneling regime. We consider a model describing…
Electron-electron interactions in a one-dimensional quantum wire spin filter
P. Devillard, A. Crepieux, K. I. Imura +1
The combined presence of a Rashba and a Zeeman effect in a ballistic one-dimensional conductor generates a spin pseudogap and the possibility to propagate a beam with well defined…
