PIConGPU modeling of nanoplasma formation in helium nanodroplets irradiated by intense femtosecond laser pulses
Cristian Medina, Klaus Steiniger, Brian Edward Marre +15
Helium nanodroplets provide a unique and versatile platform for investigating strong-field-driven nanoplasma dynamics. In this work, we present large-scale, GPU-accelerated particl…
Nanoscale Confinement Enhances Ultrafast Demagnetization
Yoav William Windsor, Tobias Lojewski, Moumita Kundu +21
Nanoscale miniaturization has revolutionized the field of spintronics by enabling exponential growth in areal bit density. A similar leap is also expected in device speeds through…
XUV fluorescence as a probe of interatomic Coulombic decay of resonantly excited He nanodroplets
Keshav Sishodia, Ltaief Ben Ltaief, Niklas Scheel +15
Superfluid He nanodroplets resonantly excited by extreme ultraviolet (XUV) pulses exhibit complex relaxation dynamics, including the formation of metastable excited He atoms tr…
FairGridSearch: A Framework to Compare Fairness-Enhancing Models
Shih-Chi Ma, Tatiana Ermakova, Benjamin Fabian
Machine learning models are increasingly used in critical decision-making applications. However, these models are susceptible to replicating or even amplifying bias present in real…
Femtosecond spin-state switching dynamics of spin-crossover molecules condensed in thin films
Lea Kämmerer, Gérald Kämmerer, Manuel Gruber +22
The photoinduced switching of Fe(II)-based spin-crossover complexes from singlet to quintet takes place at ultrafast time scales. This a priori spin-forbidden transition triggered…
Evaluation of ultrasound sensors for transcranial photoacoustic sensing and imaging
Thomas Kirchner, Claus Villringer, Jan Laufer
Biomedical photoacoustic (PA) imaging is typically used to exploit absorption-based contrast in soft tissue at depths of several centimeters. When it is applied to measuring PA wav…
Long-lasting XUV activation of helium nanodroplets for avalanche ionization
C. Medina, A. Ø. Lægdsmand, L. Ben Ltaief +13
We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. In…
Bright continuously-tunable VUV source for ultrafast spectroscopy
Lucie Jurkovičová, Ltaief Ben Ltaief, Andreas Hult Roos +14
Ultrafast electron dynamics drive phenomena such as photochemical reactions, catalysis, and light harvesting. To capture such dynamics in real-time, femtosecond to attosecond light…
Wavelength Dependence of Image Quality Metrics and Seeing Parameters and their Relation to Adaptive Optics Performance
Robert Kamlah, Meetu Verma, Andrea Diercke +1
Ground-based solar observations are severely affected by Earth's turbulent atmosphere. As a consequence, observed image quality and prevailing seeing conditions are closely related…
Peierls distortion, magnetism, and high hardness of manganese tetraboride
Huiyang Gou, Alexander A. Tsirlin, Elena Bykova +10
We report crystal structure, electronic structure, and magnetism of manganese tetraboride, MnB4, synthesized under high-pressure high-temperature conditions. In contrast to superco…
Discovery of a superhard iron tetraboride superconductor
Huiyang Gou, Natalia Dubrovinskaia, Elena Bykova +11
Single crystals of novel orthorhombic (space group Pnnm) iron tetraboride FeB4 were synthesised at pressures above 8 GPa and high temperatures. Magnetic susceptibility measurements…
