Vorticity of Twisted Spinor Fields
Andrei Afanasev, Carl E. Carlson, Asmita Mukherjee
Spinor fields with a vortex structure in free space that allow them to have arbitrary integer orbital angular momentum along the direction of motion have been studied for some time…
Superkicks and the photon angular and linear momentum density
Andrei Afanasev, Carl E. Carlson, Asmita Mukherjee
We address a problem of proper definition of momentum density for spatially structured electromagnetic fields. We show that the expressions for the momentum and angular momentum ob…
Recoil Momentum Effects in Quantum Processes Induced by Twisted Photons
Andrei Afanasev, Carl E. Carlson, Asmita Mukherjee
We consider physical processes caused by the twisted photons for a wide range of energy scales, from optical (eV) to nuclear (MeV) to high-energy gamma-rays (TeV). We demonstrate t…
High-Multipole Excitations of Hydrogen-Like Atoms by Twisted Photons near Phase Singularity
Andrei Afanasev, Carl E. Carlson, Asmita Mukherjee
We calculate transition amplitudes and cross sections for excitation of hydrogen-like atoms by the twisted photon states, or photon states with angular momentum projection on the d…
Novel Properties of Twisted-Light Absorption
Andrei Afanasev, Carl E. Carlson, Asmita Mukherjee
We discuss novel features of twisted-light absorption both by hydrogen-like atoms and by micro-particles. First, we extend the treatment of atomic photoexcitation by twisted photon…
Off-axis excitation of hydrogenlike atoms by twisted photons
Andrei Afanasev, Carl E. Carlson, Asmita Mukherjee
We show that the twisted photon states, or photon states with large () angular momentum projection () in the direction of motion, can photoexcite atomic levels for a…
