In this lecture a new formalism for constructing electromagnetic surface sources for static axisymmetric electrovacs is presented. The electrostatic and magnetostatic sources are derived from the discontinuities of the scalar potentials. This formalism allows the inclusion of two kinds of dipole sources: Sheets of dipoles and the dipole moment of a distribution of monopoles. It is a generalizat...
We compute ab initio cross sections for cold collisions of Rb atoms with OH radicals. We predict collision rate constants of order 10(-11) cm3/s at temperatures in the range 10-100 mK at which molecules have already been produced. However, we also find that in these collisions the molecules have a strong propensity for changing their internal state, which could make sympathetic cooling of OH in...
We explore the possibility offered by magnetic materials with cubic anisotropy to realize reconfigurable magnonic crystals a very simple geometry working at zero field. As proof of concept, we use micromagnetic simulations calculate static and dynamic configurations squared antidot lattice made ${\mathrm{Co}}_{2}\mathrm{Mn}\mathrm{Si}$ Heusler alloy having an constant about 17 \ifmmode\times\el...
The magnetostatic interaction between two oppositely charged transverse domain walls (TDWs) in adjacent Permalloy nanowires is experimentally demonstrated. The dependence of the pinning strength on wire separation is investigated for distances between 13 and 125 nm. The results can be described fully by considering the distribution of magnetic charge within rigid, isolated TDWs. Alternative DW ...
