For a temporal soliton, this refractive index change creates a traveling potential, which can serve as a waveguide for another optic ...

Lower bounds for quantum communication complexity
... It is easy to see that a deterministic protocol partitions the communication matrix into a set of monochromatic rectangles, each corresponding to the set of inputs sharing the same communication string produced in the run of the protocol. The above notion of weakly unbounded error protocols coincide ...

Applied Bohmian mechanics

This review focuses on the use of nonrelativistic Bohmian mechanics to address practical problems, rather than on its interpretation. Although the Bohmian and standard ...
