Theory of x-ray scattering from optically pumped excitons in atomically thin semiconductors

Joris Sturm, Andrei Benediktovitch, Nina Rohringer +1

We propose a framework to explore the internal charge distribution of mesoscopic quasiparticles by inelastic x-ray scattering, while also accounting for the conventional scattering…

Spin waves excited by hard x-ray transient gratings

Peter R. Miedaner, Alexei A. Maznev, Mykola Biednov +49

Recent progress in ultrafast x-ray sources helped establish x-rays as an important tool for probing lattice and magnetic dynamics initiated by femtosecond optical pulses. Here, we…

Modelling many-body quantum dynamics with stochastic trajectories: a critical test on the Tavis-Cummings model

A. Leonau, S. Chuchurka, V. Sukharnikov +2

We critically explore the applicability of a recently proposed framework to sample the quantum dynamics of a many-body quantum system interacting with light by stochastic trajector…

Attosecond Inner-Shell Lasing at Angstrom Wavelengths

Thomas M. Linker, Aliaksei Halavanau, Thomas Kroll +34

Since the invention of the laser nonlinear effects such as filamentation, Rabi-cycling and collective emission have been explored in the optical regime leading to a wide range of s…

Letter of Intent: Towards a Vacuum Birefringence Experiment at the Helmholtz International Beamline for Extreme Fields

N. Ahmadiniaz, C. Bähtz, A. Benediktovitch +49

Quantum field theory predicts a nonlinear response of the vacuum to strong electromagnetic fields of macroscopic extent. This fundamental tenet has remained experimentally challeng…
