The photon, its mode function and complementarity
Ralf Menzel, Robert Marx, Dirk Puhlmann +2
We probe the principle of complementarity by performing a double-slit experiment based on entangled photons created by spontaneous parametric down-conversion from a pump mode in a…
Entanglement, complementarity, and vacuum fields in spontaneous parametric down-conversion
Ralf Menzel, Axel Heuer, Peter W. Milonni
Using two crystals for spontaneous parametric down-conversion in a parallel setup, we observe two-photon interference with high visibility. The high visibility is consistent with c…
Complementarity and light modes
Ralf Menzel
In quantum physics we are confronted with new entities which consist indivisible of an energy packet and a coupled wave. The complementarity principle for certain properties of the…
Gravitational properties of light - The emission of counter-propagating laser pulses from an atom
Dennis Rätzel, Martin Wilkens, Ralf Menzel
The gravitational field of a laser pulse, although not detectable at the moment, comes with a peculiar feature which continues to attract attention; cause and effect propagate with…
Commissioning experience and beam physics measurements at the SwissFEL Injector Test Facility
T. Schietinger, M. Pedrozzi, M. Aiba +92
The SwissFEL Injector Test Facility operated at the Paul Scherrer Institute between 2010 and 2014, serving as a pilot plant and testbed for the development and realization of Swiss…
The effect of polarization entanglement in photon-photon scattering
Dennis Rätzel, Martin Wilkens, Ralf Menzel
It is found that the differential cross section of photon-photon scattering is a function of the degree of polarization entanglement of the two-photon state. A reduced, general exp…
Gravitational properties of light - The gravitational field of a laser pulse
Dennis Rätzel, Martin Wilkens, Ralf Menzel
The gravitational field of a laser pulse of finite lifetime, is investigated in the framework of linearized gravity. Although the effects are very small, they may be of fundamental…
The effect of entanglement in gravitational photon-photon scattering
Dennis Rätzel, Martin Wilkens, Ralf Menzel
The differential cross section for gravitational photon-photon scattering calculated in Perturbative Quantum Gravity is shown to depend on the degree of polarization entanglement o…
Transverse distinguishability of entangled photons with arbitrarily shaped spatial near- and far-field distributions
Robert Elsner, Dirk Puhlmann, Gregor Pieplow +2
Entangled photons generated by spontaneous parametric down conversion inside a nonlinear crystal exhibit a complex spatial photon count distribution. A quantitative description of…
Phase memory across two single photon interferometers including wavelength conversion
Axel Heuer, Sebastian Raabe, Ralf Menzel
Detailed investigations of single photon 1st-order interferences of separated emitters allow for analyzing the role of the mode function in quantum optics. In an earlier Young's do…
Enhanced two-photon absorption using true thermal light
Andreas Jechow, Michael Seefeldt, Henning Kurzke +2
Two-photon excited fluorescence (TPEF) is a standard technique in modern microscopy but still affected by photo-damage of the probe. It was proposed that TPEF can be enhanced by us…
