Absorption of Circularly Polarized Light by Solids
physica status solidi (b), 1984AbstractThe multiphoton absorption rate of circularly polarized light, by direct‐gap crystals, is investigated following a non‐perturbative scheme proposed by Jones and Reiss. It is possible to derive closed analytical solutions, for the N‐photon transition rate, valid for all field strengths of practical interest.

Stabilization in relativistic photoionization with circularly polarized light
Physical Review A, 1994Relativistic ionization rates and related phenomena are calculated for ground-state hydrogen atoms in the presence of a circularly polarized electromagnetic field. A Dirac formalism is used, with spin effects fully included. A primary purpose of this work is to explore the effects of relativity on atomic strong-field stabilization.

Photonenergy‐Controlled Symmetry Breaking with Circularly Polarized Light
Angewandte Chemie International Edition, 2013AbstractCircularly polarized light (CPL) is known to be a true chiral entity capable of generating absolute molecular asymmetry. However, the degree of inducible optical activity depends on the λ of the incident CPL. Exposure of amorphous films of rac‐alanine to tunable CPL led to enantiomeric excesses (ee) which not only follow the helicity but also ...

Compton scattering for circularly polarized light
Physical Review D, 1982Angular momentum coupling theory indicates that some generalizations of the Klein-Nishina cross section for Compton scattering to circularly polarized light are invalid. A corrected expression is given. The analysis illustrates the extent to which a Feynman diagram may be interpreted naively as an angular momentum coupling diagram.

Bloch oscillations for circularly polarized light
Physics Letters A, 2008Abstract All previous investigations on the Bloch oscillations of waves focus on scalar waves. Here we demonstrate, for the first time, the existence of Bloch oscillations of vector fields for circularly polarized light (CPL) propagating through a designed liquid crystal structure.

Dynamic nuclear self-polarization with circularly polarized light
Journal of Applied Physics, 2011Lattice nuclei of III-V type semiconductors can be self-polarized through the contact hyperfine interaction with artificially excited conduction electrons at extremely low temperatures. In the self-polarization process, a positive feedback between the nuclear magnetization and the expansion of the energy splitting of the conduction electron states due ...

Helical polymers for dissymmetric circularly polarized light imaging
Nature, 2023Control of the spin angular momentum (SAM) carried in a photon provides a technologically attractive element for next-generation quantum networks and spintronics1-5. However, the weak optical activity and inhomogeneity of thin films from chiral molecular crystals result in high noise and uncertainty in SAM detection.

Suppression of Multiphoton Ionization with Circularly Polarized Coherent Light
Physical Review Letters, 1986Multiphoton ionization in xenon has been studied with 1064-nm circularly polarized coherent light, producing electrons with energies up to 15 eV. A strong suppression of the cross section is observed for electrons below 4 eV, but not for linearly polarized light at the same intensity.

Chiral Plasmonic Nanostructures Fabricated by Circularly Polarized Light
Nano Letters, 2018The chirality of materials results in a wide variety of advanced technologies including image display, data storage, light management including negative refraction, and enantioselective catalysis and sensing. Here, we introduce chirality to plasmonic nanostructures by using circularly polarized light as the sole chiral source for the first time.

Holographic subtraction with circularly polarized light
Optics Communications, 1972Abstract Holographic recordings made with circularly polarized light of opposite sense in the reference and object beams are used for providing subtraction of images. Double exposure and single exposure schemes are described, the technique being advantageous in particular for non-real time analysis of the subtracted reconstruction.
