Robust scenario for the generation of non-equilibrium topological fluctuation states
Kathinka Gerlinger, Rein Liefferink, Michael Schneider +12
The recently discovered topological fluctuation state provides a fascinating new perspective on the ultrafast emergence of topology in condensed matter systems. However, rather lit…
Extreme ultraviolet transient gratings: A tool for nanoscale photoacoustics
L. Foglia, R. Mincigrucci, A. A. Maznev +23
Collective lattice dynamics determine essential aspects of condensed matter, such as elastic and thermal properties. These exhibit strong dependence on the length-scale, reflecting…
High energy-resolution transient ghost absorption spectroscopy
Alok Kumar Tripathi, Yishai Klein, Edward Strizhevsky +10
We demonstrate the measurement of ultrafast dynamics using ghost spectroscopy and a pump-probe approach with an optical pump and a short-wavelength radiation probe. The ghost spect…
Terahertz electric-field driven dynamical multiferroicity in SrTiO
M. Basini, M. Pancaldi, B. Wehinger +5
The emergence of collective order in matter is among the most fundamental and intriguing phenomena in physics. In recent years, the ultrafast dynamical control and creation of nove…
Terahertz ionic Kerr effect: Two-phonon contribution to the nonlinear optical response in insulators
Martina Basini, Mattia Udina, Matteo Pancaldi +3
The THz Kerr effect measures the birefringence induced in an otherwise isotropic material by a strong THz pulse driving the Raman-active excitations of the systems. Here we provide…
All-optical switching on the nanometer scale excited and probed with femtosecond extreme ultraviolet pulses
Kelvin Yao, Felix Steinbach, Martin Borchert +13
Ultrafast control of magnetization on the nanometer length scale, in particular all-optical switching, is key to putting ultrafast magnetism on the path towards future technologica…
High-resolution absorption measurements with free-electron lasers using ghost spectroscopy
Yishai Klein, Edward Strizhevsky, Flavio Capotondi +10
We demonstrate a simple and robust high-resolution ghost spectroscopy approach for x-ray and extreme ultraviolet absorption spectroscopy at free-electron laser sources. Our approac…
Megahertz-rate Ultrafast X-ray Scattering and Holographic Imaging at the European XFEL
Nanna Zhou Hagström, Michael Schneider, Nico Kerber +97
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, from chemistry to biology, giving researchers acce…
