The zero modes and zero resonances of massless Dirac operators
Yoshimi Saito, Tomio Umeda
The zero modes and zero resonances of the Dirac operator are discussed, where is the triple of Dirac matrices, $ D=\frac{1}{i}…
Fulde-Ferrel-Larkin-Ovchinnikov State due to Antisymmetric Spin-Orbit-Coupling in Noncentrosymmetric Superconductivity CePtSi
Hiroko Tanaka, Hirono Kaneyasu, Yasumasa Hasegawa
When the inversion symmetry is broken, the spin-orbit coupling reduces the transition temperature of some types of spin triplet superconductivity, which is similar to the case that…
Shifting donor-acceptor photoluminescence in N-doped ZnO
Takayuki Makino, A. Tsukazaki, A. Ohtomo +2
We have grown nitrogen-doped ZnO films grown by two kinds of epitaxial methods on lattice-matched ScAlMgO substrates. We measured the photoluminescence (PL) of the two kinds of…
Hole Transport in p-Type ZnO
Takayuki Makino, Akira Ohtomo, A. Tsukazaki +2
A two-band model involving the A- and B-valence bands was adopted to analyze the temperature dependent Hall effect measured on N-doped \textit{p}-type ZnO. The hole transport chara…
Zero modes of tight binding electrons on the honeycomb lattice
Yasumasa Hasegawa, Rikio Konno, Hiroki Nakano +1
Tight binding electrons on the honeycomb lattice are studied where nearest neighbor hoppings in the three directions are and , respectively. For the isotropic case,…
Effects of Electron Correlation near Spin-Density-Wave on Angle Dependence of Magnetoconductivity
Hirono Kaneyasu, Keita Kishigi, Yasumasa Hasegawa
The effect of electron correlation on the angle dependence of magnetoconductivity is studied in quasi-one-dimensional organic conductors. We investigated the effect on the basis of…
