Generation of spin currents via Raman scattering.
We show theoretically that stimulated spin-flip Raman scattering can be used to inject spin currents in doped semiconductors with spin-split bands. A pure spin current, where oppositely oriented spins move in opposite directions, can be injected in zinc blende crystals and structures. The calculated spin current should be detectable by pump-probe optical spectroscopy and anomalous Hall effect m...
متن کاملSideward Stimulated Raman Scattering
The SRS of a short laser pulse is important in the contexts of particle acceleration2 and inertial confinement fusion.3,4 In previous studies of the spatiotemporal evolution of SRS,5–13 the Stokes waves were allowed to pass freely through the pulse boundaries. However, the radial ponderomotive force associated with the pulse can expel plasma from the neighborhood of the pulse axis, in which cas...
متن کاملStimulated photon emission and two-photon Raman scattering in a coupled-cavity QED system
We study the scattering problem of photon and polariton in a one-dimensional coupled-cavity system. Analytical approximate analysis and numerical simulation show that a photon can stimulate the photon emission from a polariton through polariton-photon collisions. This observation opens the possibility of photon-stimulated transition from insulating to radiative phase in a coupled-cavity QED sys...
متن کاملMulticolor stimulated Raman scattering microscopy
Stimulated Raman scattering (SRS) microscopy has opened up a wide range of biochemical imaging applications by probing a particular Raman-active molecule vibrational mode in the specimen. However, the original implementation with picosecond pulse excitation can only realize rapid chemical mapping with a single Raman band. Here we present a novel SRS microscopic technique using a grating-based p...
متن کاملThe Spin Structure of a Polarized Photon
We show that the rst moment of the spin-dependent structure function g 1 (x;Q ) of a real photon vanishes independent of the momentum transfer Q it is probed with. This result is non-perturbative: it holds to all orders in perturbation theory in abelian and non-abelian gauge theory and at every twist.
