Imaging mesoscopic spin Hall flow: Spatial distribution of local spin currents and spin densities in and out of multiterminal spin-orbit coupled semiconductor nanostructures
Branislav K. Nikolic, Liviu P. Zarbo, Satofumi Souma
We introduce the concept of bond spin current, which describes the spin transport between two sites of the lattice model of a multiterminal spin-orbit (SO) coupled semiconductor na…
Association schemes from the action of fixing a nonsingular conic in PG(2,q)
Henk D. L. Hollmann, Qing Xiang
The group has an embedding into such that it acts as the group fixing a nonsingular conic in . This action affords a coherent configuration on…
Transverse Spin-Orbit Force in the Spin Hall Effect in Ballistic Semiconductor Wires
Branislav K. Nikolic, Liviu P. Zarbo, Sven Welack
We introduce the spin and momentum dependent {\em force operator} which is defined by the Hamiltonian of a {\em clean} semiconductor quantum wire with homogeneous Rashba spin-orbit…
Outstanding Problems in Particle Astrophysics
Thomas K. Gaisser
The general features of the cosmic-ray spectrum have been known for a long time. Although the basic approaches to understanding cosmic-ray propagation and acceleration have also be…
