Field-assisted birefringent Compton scattering
N. Ahmadiniaz, T. E. Cowan, M. Ding +4
Motivated by experimental initiatives such as the Helmholtz International Beamline for Extreme Fields (HIBEF), we study Compton scattering of x-rays at electrons in a strong extern…
Ginzburg effect in a dielectric medium with dispersion and dissipation
Sascha Lang, Roland Sauerbrey, Ralf Schützhold +1
As a quantum analog of Cherenkov radiation, an inertial photon detector moving through a medium with constant refractive index may perceive the electromagnetic quantum fluctuat…
Self-Focussing of an Intense X-Ray Beam in Vacuum
Roland Sauerbrey, Christian Kohlfürst
The quantum vacuum shows an intensity-dependent nonlinear index of refraction. Consequently, we may consider vacuum as a non-linear medium enabling, at sufficiently high field stre…
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…
On the Heisenberg limit for detecting vacuum birefringence
N. Ahmadiniaz, T. E. Cowan, R. Sauerbrey +3
Quantum electrodynamics predicts the vacuum to behave as a non-linear medium, including effects such as birefringence. However, for experimentally available field strengths, this v…
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…
