Enhanced optical conductivity and many-body effects in strongly-driven photo-excited semi-metallic graphite
T. P. H. Sidiropoulos, N. Di Palo, D. E. Rivas +4
The excitation of quasi-particles near the extrema of the electronic band structure is a gateway to electronic phase transitions in condensed matter. In a many-body system, quasi-p…
Multiple-core-hole resonance spectroscopy with ultraintense X-ray pulses
Aljoscha Rörig, Sang-Kil Son, Tommaso Mazza +14
Understanding the interaction of intense, femtosecond X-ray pulses with heavy atoms is crucial for gaining insights into the structure and dynamics of matter. One key aspect of non…
Generation of Large Vortex-Free Superfluid Helium Nanodroplets
Anatoli Ulmer, Andrea Heilrath, Björn Senfftleben +38
Superfluid helium nanodroplets are an ideal environment for the formation of metastable, self-organized dopant nanostructures. However, the presence of vortices often hinders their…
Resonance-enhanced multiphoton ionization in the x-ray regime
Aaron C. LaForge, Sang-Kil Son, Debadarshini Mishra +16
Here, we report on the nonlinear ionization of argon atoms in the short wavelength regime using ultraintense x rays from the European XFEL. After sequential multiphoton ionization,…
Probing the energy conversion pathways between light, carriers and lattice in real time with attosecond core-level spectroscopy
T. P. H. Sidiropoulos, N. Di Palo, D. E. Rivas +16
Detection of the energy conversion pathways, between photons, charge carriers, and the lattice is of fundamental importance to understand fundamental physics and to advance materia…
Fano resonances in saturable waveguide arrays
Uta Naether, Daniel E. Rivas, Manuel A. Larenas +2
We study a waveguide array with an embedded nonlinear saturable impurity. We solve the impurity problem in closed form and find the nonlinear localized modes. Next, we consider the…
