Photovoltaic Hall effect in graphene
Takashi Oka, Hideo Aoki
Response of electronic systems in intense lights (AC electric fields) to DC source-drain fields is formulated with the Floquet method. We have then applied the formalism to graphen…
Edge states for the n=0 Laudau level in graphene
Mitsuhiro Arikawa, Yasuhiro Hatsugai, Hideo Aoki
In the anomalous quantum Hall effect (QHE), a hallmark of graphene, nature of the edge states in magnetic fields poses an important question, since the edge and bulk should be inti…
Edge states in graphene in magnetic fields -- a speciality of the edge mode embedded in the n=0 Landau band
Mitsuhiro Arikawa, Yasuhiro Hatsugai, Hideo Aoki
While usual edge states in the quantum Hall effect(QHE) reside between adjacent Landau levels, QHE in graphene has a peculiar edge mode at E=0 that reside right within the n=0 Land…
Topological low-energy modes in N=0 Landau levels of graphene: a possibility of a quantum-liquid ground state
Yasuhiro Hatsugai, Takahiro Fukui, Hideo Aoki
We point out that the zero-energy Landau level of Dirac fermions in graphene can be, in the presence of a repulsive electron-electron interaction, split into two (levels) associate…
Accurate Model of a Vertical Pillar Quantum Dot
P. A. Maksym, Y. Nishi, D. G. Austing +4
An accurate model of a vertical pillar quantum dot is described. The full three dimensional structure of the device containing the dot is taken into account and this leads to an ef…
