Quantum and classical phase-space dynamics of a free-electron laser
C. Moritz Carmesin, Peter Kling, Enno Giese +2
In a quantum mechanical description of the free-electron laser (FEL) the electrons jump on discrete momentum ladders, while they follow continuous trajectories according to the cla…
Regimes of atomic diffraction: Raman versus Bragg diffraction in retroreflective geometries
Sabrina Hartmann, Jens Jenewein, Enno Giese +4
We provide a comprehensive study of atomic Raman and Bragg diffraction when coupling to a pair of counterpropagating light gratings (double diffraction) or to a single one (single…
Quantum, Nonlocal Aberration Cancellation
A. Nicholas Black, Enno Giese, Boris Braverman +3
Phase distortions, or aberrations, can negatively influence the performance of an optical imaging system. Through the use of position-momentum entangled photons, we nonlocally corr…
A high-gain Quantum free-electron laser: emergence & exponential gain
Peter Kling, Enno Giese, C. Moritz Carmesin +2
We derive an effective Dicke model in momentum space to describe collective effects in the quantum regime of a free-electron laser (FEL). The resulting exponential gain from a sing…
Full-field mode sorter using two optimized phase transformations for high-dimensional quantum cryptography
Robert Fickler, Frédéric Bouchard, Enno Giese +3
High-dimensional encoding schemes have emerged as a novel way to perform quantum information tasks. For high dimensionality, temporal and transverse spatial modes of photons are th…
Proper time in atom interferometers: Diffractive versus specular mirrors
Enno Giese, Alexander Friedrich, Fabio Di Pumpo +4
We compare a conventional Mach-Zehnder light-pulse atom interferometer based on diffractive mirrors with one that uses specular reflection. In contrast to diffractive mirrors that…
