X-ray driven displacive excitation of coherent phonons
Oleg Dogadov, Remi Claude, Christoph Emeis +29
Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide lim…
Breakdown of the isotropic asymptotic approximation in two-colour photoionisation
Sooraj Rajendran, Miguel Benito de Lama, Praveen Kumar Maroju +24
The Wigner delay is defined as the energy derivative of the scattering phase of a particle in a given potential, unveiling the time taken (or gained) due to the interaction. The ch…
The Super Fine-Grained Detector for the T2K neutrino oscillation experiment
S. Abe, H. Alarakia-Charles, I. Alekseev +169
The magnetised near detector ND280 of the long-baseline neutrino experiment T2K has been upgraded to improve its detection performance and, consequently, enhance our understanding…
Ultrafast dynamics of vibronically dressed core-excitons in graphite: a femtosecond RIXS perspective
Marco Malvestuto, Beatrice Volpato, Elena Babici +16
This study demonstrates one of the first implementations of time-resolved resonant inelastic X-ray scattering (tr-RIXS), marking a seminal extension of RIXS spectroscopy into the u…
Mitigation of the Microbunching Instability Through Transverse Landau Damping
A. D. Brynes, G. Perosa, C. -Y. Tsai +14
The microbunching instability has been a long-standing issue for high-brightness free-electron lasers (FELs), and is a significant show-stopper to achieving full longitudinal coher…
Three-dimensional theory of superradiant free-electron lasers
River R. Robles, Luca Giannessi, Agostino Marinelli
The soliton-like superradiant regime of free-electron lasers (FEL) offers a promising path towards ultrashort pulses, beyond the natural limit dictated by the bandwidth of the high…
Strong-field quantum control in the extreme ultraviolet using pulse shaping
Fabian Richter, Ulf Saalmann, Enrico Allaria +40
Tailored light-matter interactions in the strong coupling regime enable the manipulation and control of quantum systems with up to unit efficiency, with applications ranging from q…
Generation of entanglement using a short-wavelength seeded free-electron laser
Saikat Nandi, Axel Stenquist, Asimina Papoulia +25
Quantum entanglement between the degrees of freedom encountered in the classical world is challenging to observe due to the surrounding environment. To elucidate this issue, we inv…
Nanoscale transient polarization gratings
Laura Foglia, Björn Wehinger, Giovanni Perosa +24
We present the generation of transient polarization gratings at the nanoscale, achieved using a tailored accelerator configuration of the FERMI free electron laser. We demonstrate…
Diffraction imaging of light induced dynamics in xenon-doped helium nanodroplets
Bruno Langbehn, Yevheniy Ovcharenko, Andrew Clark +23
We have explored the light induced dynamics in superfluid helium nanodroplets with wide-angle scattering in a pump-probe measurement scheme. The droplets are doped with xenon atoms…
Time-resolved study of resonant interatomic Coulombic decay in helium nanodroplets
A. C. LaForge, R. Michiels, Y. Ovcharenko +30
When weakly-bound complexes are multiply excited by intense electromagnetic radiation, energy can be exchanged between neighboring atoms through a type of resonant interatomic Coul…
Time-resolved observation of interatomic Coulombic decay induced by two-photon double excitation of Ne
T. Takanashi, N. V. Golubev, C. Callegari +46
The hitherto unexplored two-photon doubly-excited states [Ne()] were experimentally identified using the seeded, fully coherent, intense extreme ultraviolet…
Beyond the Limits of 1D Coherent Synchrotron Radiation
A. D. Brynes, P. Smorenburg, I. Akkermans +21
An understanding of collective effects is of fundamental importance for the design and optimisation of the performance of modern accelerators. In particular, the design of an accel…
Coherent control with a short-wavelength Free Electron Laser
K. C. Prince, E. Allaria, C. Callegari +37
XUV and X-ray Free Electron Lasers (FELs) produce short wavelength pulses with high intensity, ultrashort duration, well-defined polarization and transverse coherence, and have bee…
