Topological strings, strips and quivers

Abstract We find a direct relation between quiver representation theory and open topological string theory on a class of toric Calabi-Yau manifolds without compact four-cycles, also referred to Nail Polish as strip geometries.We show that various quantities that characterize open topological string theory on these manifolds, such as partition funct

Generation of high-density biskyrmions by electric current

Spintronics: Generation of magnetic biskyrmions by electric current Electric current can generate and control the density of magnetic biskyrmions in a centrosymmetric MnNiGa alloy at room temperature.Skyrmions are chiral spin textures whose spins point in all directions wrapping a sphere, making them topological in nature.Topological protection, co
