WebSep 8, 2013 · A magnetic skyrmion 1, 2, 3, 4, 5, 6, 7, 8 is a topologically stable spin vortex structure, as observed in chiral-lattice helimagnets, and is one example of such a structure. The spin swirling... WebAug 22, 2012 · Dual electromagnetism: Helicity, spin, momentum, and angular momentum. The dual symmetry between electric and magnetic fields is an important intrinsic property of Maxwell equations in free space. This symmetry underlies the conservation of optical helicity, and, as we show here, is closely related to the separation of spin and orbital … WebMar 20, 2013 · This symmetry underlies the conservation of optical helicity and, as we show here, is closely related to the separation of spin and orbital degrees of freedom of light (the helicity flux coincides with the spin angular momentum). However, in the standard field-theory formulation of electromagnetism, the field Lagrangian is not dual symmetric. buckskin clothing images clipart
