Spatial-temporal correlations of the light of an ion crystal — •Stefan Richter1, Sebastian Wolf2, Andre Weber3, Yury Prokazov4, Evgeny Turbin4, Joachim von Zanthier1, and Ferdinand Schmidt-Kaler21Institut für Optik, Information und Photonik, Universität Erlangen-Nürnberg, Staudtstraße 1, 91058 Erlangen — 2QUANTUM, Institut für Physik, Johannes Gutenberg-Universität Mainz, 55128 Mainz, Germany — 3LIN, Leibniz Institute for Neurobiology, Brenneckestraße 6, 39118 Magdeburg — 4Photonscore GmbH, Brenneckestraße 6, 39118 Magdeburg

We measured first [1] and second order correlation functions of the light spontaneously emitted from a trapped, cold two-ion crystal for various detector positions in the temporal regime. Strikingly, the g(2)(x, τ) signal shows bunching or antibunching for different observer positions [2]. Position sensitive Micro Channel Plate detectors developed for applications in fluorescence lifetime microscopy combining a high spatial resolution with temporal resolution. By using two detectors in correlation mode, it is possible to implement intensity interferometry with the light of a two-ion crystals. The spatial modulation of g(2)(x1, x2, τ) was predicted in [3] and can now be measured by recording the corresponding two photon events for any time difference Δ T and corresponding positions x1 and x2. After the event stream is recorded, the correlations for arbitrary geometries can be reconstructed.
