Evidence for Uniform Coexistence of Ferromagnetism and Unconventional Superconductivity in UGe_2: A ^73Ge-NQR Study under Pressure
H. Kotegawa, A. Harada, S. Kawasaki +8
We report on the itinerant ferromagnetic superconductor UGe_2 through ^73Ge-NQR measurements under pressure (P). The P dependence of the NQR spectrum signals a first-order transiti…
Chirality Selection in Crystallization
Yukio Saito, Hiroyuki Hyuga
A cluster growth model is proposed to study chiral symmetry breaking in stirred crystallization from an achiral element. Achiral monomers are assumed to coagulate to form chiral cl…
Domain wall displacement triggered by an AC current below threshold
Gen Tatara, Eiji Saitoh, Masahiko Ichimura +1
It is theoretically demonstrated that a displacement of a pinned domain wall, typically of order of m, can be driven by use of an ac current which is below threshold value. The…
Recovery of Full N=1 Supersymmetry in Non(anti-)commutative Superspace
Akifumi Sako, Toshiya Suzuki
We investigate SUSY of Wess-Zumino models in non(anti-)commutative Euclidean superspaces. Non(anti-)commutative deformations break 1/2 SUSY, then non(anti-)commutative Wess-Zumino…
Random Deposition Model with a Constant Capture Length
Paolo Politi, Yukio Saito
We introduce a sequential model for the deposition and aggregation of particles in the submonolayer regime. Once a particle has been randomly deposited on the substrate, it sticks…
Current-Induced Entanglement of Nuclear Spins in Quantum Dots
M. Eto, T. Ashiwa, M. Murata
We propose an entanglement mechanism of nuclear spins in quantum dots driven by the electric current accompanied by the spin flip. This situation is relevant to a leakage current i…
