ABSTRACT
In a two-dimensional magnetic nanowire, it is possible to engineer collisions between two domain walls put into motion by an externally applied field. We show that the topological defects that define the domain wall can be controlled to allow for both domain wall annihilation and preservation during the collisions as long as the wire remains thin. The preservation process can be used to release pinned domain walls from notches with small applied fields.

    We discuss the AGK rules for the exchange of an arbitrary number of reggeized gluons in perturbative QCD in the high-energy limit. The results include the cancellation of corrections to single jet and double jet inclusive cross sections, both for hard and soft rescattering contributions.

    With experimental data of ${\bar p}$ annihilation at rest on nuclei of 4He, collected by the Obelix spectrometer (LEAR, CERN), we have studied a number of reactions with 4 and 5 charged particles in the final state, distinguishing the annihilations on more than one nucleon, and with strangeness...
