Stabilization mechanism of edge states in graphene
K. Sasaki, S. Murakami, R. Saito
It has been known that edge states of a graphite ribbon are zero-energy, localized eigen-states. We show that next nearest-neighbor hopping process decreases the energy of the edge…
Intrinsic Spin Hall Effect
Shuichi Murakami
A brief review is given on the spin Hall effect, where an external electric field induces a transverse spin current. It has been recognized over 30 years that such effect occurs du…
Spin Hall effect of conserved current: Conditions for a nonzero spin Hall current
Naoyuki Sugimoto, Shigeki Onoda, Shuichi Murakami +1
We study the spin Hall effect taking into account the impurity scattering effect as general as possible with the focus on the definition of the spin current. The conserved bulk spi…
Controlling edge states of zigzag carbon nanotubes by the Aharonov-Bohm flux
K. Sasaki, S. Murakami, R. Saito +1
It has been known theoretically that localized states exist around zigzag edges of a graphite ribbon and of a carbon nanotube, whose energy eigenvalues are located between conducti…
Re-parameterization Invariance in Fractional Flux Periodicity
Shuichi Murakami, Ken-ichi Sasaki, Riichiro Saito
We analyze a common feature of a nontrivial fractional flux periodicity in two-dimensional systems. We demonstrate that an addition of fractional flux can be absorbed into re-param…
Fractional Flux Periodicity in Doped Carbon Nanotubes
K. Sasaki, S. Murakami, R. Saito
An anomalous magnetic flux periodicity of the ground state is predicted in two-dimensional cylindrical surface composed of square and honeycomb lattice. The ground state and persis…
