    Laser technology is rapidly developing to the point where pulse power and intensity are expected to reach such levels that new physical processes will be able to be studied for the first time. Using simulation the authors theoretically investigate the generation of high brilliance gamma rays and electron-positron pairs during extreme intense laser interaction with a specific target.

    While circular polarization-dependent optical responses in matter are being characterized experimentally and theoretically, the effect of angular momentum has largely been overlooked. In this work, the authors formulate a definition for the optical response due to both spin and orbital angular momentum of light using numerical simulations of stacked nanorods as a demonstration.

    For most lasing and photonic applications, it is essential to control the number of lasing modes that are present. In this work, an interface between two topologically distinct photonic crystals is used to ensure single-mode lasing with enhanced light-matter interactions due to a near-diffraction-limited mode volume.
