Entangled photons from para-positronium decay: Do coincidences from scattered photons imply a Bell state?
Paul Joos, Peter Kling
Electron and positron can form a meta-stable bound state called positronium that decays via pair annihilation. We show how polarization-dependent Compton scattering can be used to…
Quantum free-electron laser oscillator
Peter Kling, Enno Giese
If the quantum mechanical recoil of the electron due to its scattering from the undulator and laser fields dominates the dynamics, a regime of the free-electron laser emerges where…
Multiphoton processes and higher resonances in the quantum regime of the free-electron laser
Peter Kling, Enno Giese
Despite exhibiting novel radiation features, the operation of the proposed quantum free-electron laser would have the drawback that the number of emitted photons is limited by one…
High-gain quantum free-electron laser: long-time dynamics and requirements
Peter Kling, Enno Giese, C. Moritz Carmesin +2
We solve the long-time dynamics of a high-gain free-electron laser in the quantum regime. In this regime each electron emits at most one photon on average, independently of the ini…
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…
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…
