• Abstract: A future gamma factory at CERN or accelerator-based gamma sources elsewhere can include the possibility of energetic twisted photons, which are photons with a structured wave front that can allow a pre-defined large angular momentum along the beam direction. Twisted photons are potentially a new tool in hadronic physics, and we consider here one possibility, namely the photoproduction of $\Delta$(1232) baryons using twisted photons. We show that particular polarization amplitudes isolate the smaller partial wave amplitudes and they are measurable without interference from the terms that are otherwise dominant.

  Vortex $gamma$ photons carrying orbital angular momenta (OAM) hold great potential for various applications. Here, we successfully generate sub-MeV vortex $gamma$ photons via all-optical inverse Compton scattering of relativistic electrons colliding with a sub-relativistic Laguerre-Gaussian laser. Our method provides the first experimental evidence for detecting vortex $gamma$ photons and opens a new perspective for investigating OAM-induced quantum phenomena in broad fields.

  Pairs of entangled vortex photons can promise new prospects of application in quantum computing and cryptography. We investigate the possibility of generating such states via two-level atom emission stimulated by a single photon wave packet. We conclude that induced emission can be used as a source of entangled vortex photons with applications in atomic physics experiments, quantum optics, and quantum information sciences.

  A laser beam is shaped by a voltage-controlled spin-to-orbital angular momentum converter q-plate device. Such a beam is then used as pump in a spontaneous parametric downconversion (SPDC) photon-pair source. We demonstrate the full pump to heralded single photon transfer of the intensity/phase distributions, as well as of the vector polarization structure.

  No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory. Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons. This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.

  We investigate the resonant elastic scattering of twisted light, carrying angular momentum, by partially stripped ions. For the incident Bessel light, the scattered radiation is shown to be in a superposition of twisted modes. This angular momentum transfer makes the resonant photon scattering an effective tool for the production of twisted x-- and even gamma--rays.
