Giant spin torque in systems with anisotropic exchange interaction cond-mat.mes-hall Control of magnetic domain wall movement by the spin-polarized current looks promising for creation of a new generation of magnetic memory devices. A necessary condition for this is the domain wall shift by a low-density current. H...

A Classical Framework for Nonlocality and Entanglement quant-ph physics.class-ph Based on our model of quantum systems as emerging from the coupled dynamics between oscillating "bouncers" and the space-filling zero-point field, a sub-quantum account of nonlocal correlations is given. This is explicitly done for the...
