Neutron Scattering Study on Competition between Hidden Order and Antiferromagnetism in U(Ru_{1-x}Rh_x)_2Si_2 (x <= 0.05)
M. Yokoyama, H. Amitsuka, S. Itoh +3
We have performed elastic and inelastic neutron scattering experiments on the solid solutions U(Ru_{1-x}Rh_x)_2Si_2 for the Ru rich concentrations: x=0, 0.01, 0.02, 0.025, 0.03, 0.…
Rational double points on supersingular K3 surfaces
Ichiro Shimada
We investigate configurations of rational double points with the total Milnor number 21 on supersingular surfaces. The complete list of possible configurations is given. As an…
Competition between hidden order and antiferromagnetism in URu_2Si_2 under uniaxial stress studied by neutron scattering
M. Yokoyama, H. Amitsuka, K. Tenya +4
We have performed elastic neutron scattering experiments under uniaxial stress sigma applied along the tetragonal [100], [110] and [001] directions for the heavy electron compound…
Accretion onto the neutron star in Be/X-ray binaries
Kimitake Hayasaki, Atsuo. T. Okazaki
We study accretion onto the neutron star in Be/X-ray binaries, using a 3D SPH code and the data imported from a high resolution simulation by Okazaki et al.\ (2002) for a coplanar…
Ideal structure of -algebras associated with -correspondences
Takeshi Katsura
We study the ideal structure of -algebras arising from -correspondences. We prove that gauge-invariant ideals of our -algebras are parameterized by certain pairs of…
Supersingular K3 surfaces in odd characteristic and sextic double planes
Ichiro Shimada
We show that every supersingular K3 surface is birational to a double cover of a projective plane.
