Coherent storage and phase modulation of single hard x-ray photons using
nuclear excitons
   [PDF]

Wen-Te Liao, Adriana Pálffy, Christoph H. Keitel
Phase-sensitive photon storage of hard x-rays in resonant scattering of light off nuclei is investigated theoretically. We show that by switching off and on again the magnetic field in the nuclear sample, phase-sensitive storage of keV-photon pulses can be achieved. Corresponding $\pi$ phase modulation of the stored photon is possible if the retrieving magnetic field is rotated by $180^{\circ}$. As phase control tests we put forward a two-target setup that allows for the formation of a magnetically induced nuclear exciton echo and presents in itself another alternative for single-photon storage. These control techniques for a single photon in the 10 keV range may provide the potential of substantially shrinking future photonic devices.
