Non-vanishing of the twisted cohomology on the complement of hypersurfaces

Yukihito Kawahara

Under the generic situation, the cohomology with the coefficients in the local system on complements of hypersurfaces vanishes except in the highest dimension. Our problem is of wh…

Transport properties of the heavy fermion superconductor PrOs $_{4}$ Sb $_{12}$

H. Sugawara, M. Kobayashi, S. Osaki +4

We have measured the electrical resistivity, thermoelectric power, Hall coefficient, and magnetoresistance (MR) on single crystals of PrOs $_{4}$ Sb $_{12}$ , LaOs $_{4}$ Sb $_{12}$ and N…

Quantum Critical Point of Itinerant Antiferromagnet in Heavy Fermion

Hiroaki Kadowaki, Yoshikazu Tabata, Masugu Sato +3

A quantum critical point (QCP) of the heavy fermion Ce(Ru_{1-x}Rh_x)_2Si_2 (x = 0, 0.03) has been studied by single-crystalline neutron scattering. By accurately measuring the dyna…

Kosterlitz-Thouless transition in planar spin models with bond dilution

Tasrief Surungan, Yukata Okabe

We study the two-dimensional bond-diluted XY and six-state clock models by Monte Carlo simulation with cluster spin updates. Various concentrations of depleted bonds were simulated…

Pseudo-conformal quaternionic CR structure on (4n+3)-dimensional manifolds

Dmitri Alekseevsky, Yoshinobu Kamishima

The purpose of this paper is to introduce a geometric structure called pseudo-conformal quaternionic CR structure on a (4n+3)-dimensional mamnifold and then exhibit a quaternionic…
