The positronium spin conversion reaction induced by spin-orbit interaction is investigated. We obtain the reaction rates during positronium-Xe and positronium-Kr collisions by using the Zeeman mixing of positronium states. At thermal energies corresponding to room temperature, the reaction rate for spin conversion due to spin-orbit interaction is found to be almost twice that for the positroniu...

We study trapped 2D atomic Bose-Einstein condensates with spin-independent interactions in the presence of an isotropic spin-orbit coupling, showing that a rich physics results from the nontrivial interplay between spin-orbit coupling, confinement and interatomic interactions. For low interactions two types of half-vortex solutions with different winding occur, whereas strong-enough repulsive i...

We investigate a spinful double quantum dot coupled to leads in pseudospin valve configuration. The interplay of interaction and interference produces, the stability diagram, rich variety current resonances modulated by system parameters. In presence ferromagnetic anisotropy, those split, turn into dips, acquire Fano shape, thus revealing synthetic spin-orbit induced on dot. A set rate equation...
