Abstract: Abstract We report that a negative optical absorption arises in a sharp band at 325 nm (energy hν2) in a nanostructured silver (n-Ag) doped poly(vinylidene fluoride) (PVF2) in a hybrid nanocomposite of films (∼100 μm thickness). Two… read more here.

Abstract: Abstract We numerically studied the spin-dependent optical torque on a 2D chiral plasmonic nanomotor excited by circularly polarized lights. An interesting phenomenon of so-called negative optical torque is demonstrated on condition that the scattering optical… read more here.

Abstract: The photons in circularly polarized light can transfer their quantized spin angular momentum to micro- and nanostructures via absorption and scattering. This normally exerts positive torque on the objects wher the sign (i.e., handedness or… read more here.
