Abstract: We compare the technique of using the orbital angular momentum (OAM) of radio waves for generating multiple channels in a radio communication scenario with traditional ...

Recently, the manipulation of the spin angular momentum (SAM)—or polarization ... by driving HHG with a bichromatic counter-rotating field with proper orbital angular momentum (OAM) [4] ...

Time-resolved measurements indicate that the switching is driven by a spin-polarized current passing through the subnanometer Ir interlayer. The magnetic properties of this model system may be tuned ...

Jupiter may have once been more than twice its current size, with a magnetic field 50 times stronger, say scientists who ...
