Abstract

A brief review of single photon free-free transitions, in which a photon is absorbed by an electron in the presence of an atom, is presented.

Generation of entanglement between spin of an electron and polarization of a photon

Naresh Chandra, R. Ghosh

This paper shows an electron and a photon, emitted in two consecutive steps from an atom following the absorption of a single photon, may be entangled in the presence of the spin-orbit interaction only. This entanglement strongly depends upon the polarization of the absorbed and of the radiated photons, kinematics of two emitted particles, and dynamics of photoionization; however, the photoemission dynamics plays no role in this entanglement. This hybrid entanglement can be used in teleporting a quantum state encoded in a flying/stationary material particle onto a light pulse, or vice versa. Such an electron-photon entanglement, in addition, will make it possible to learn about the polarization of a single photon or spin-polarization of a free electron without making any measurements on the corresponding particle itself.

SOME NEW PERSPECTIVES IN BREMSSTRAHLUNG RESEARCH

A. Maquet, Alain Dubois, Valérie Vëniard

We report the results of new theoretical calculations of the transition amplitudes and cross-sections for two distinct bremsstrahlung-related processes : i) Stimulated one-photon transitions (Free-Free Transitions) occuning in the course of electron-H atom collisions, in the presence of a strong extemal field. ii) Two-photon Bremsstrahlung, corresponding to the spontaneous emission of two distinct photons in a single electron-atom collision event. The main features of these processes will be outlined and discussed.

Rydberg single photon detection for probing 0.1-10 meV dark matter with BREAD

Abhishek Banerjee, Reza Ebadi, Surjeet Rajendran

We introduce a Rydberg-based single photon detector (SPD) for probing dark matter in the 0.1–10 meV mass range (20 GHz–2 THz). The Rydberg SPD absorbs photons produced and focused by the BREAD dish antenna and trades them for free, detectable electrons. At the lower end of the mass range, photons drive Rydberg-Rydberg transitions, which are read out via state-selective ionization. At higher masses, they directly ionize the Rydberg atoms.
