EquiFiLM: Charge-Conditioned Equivariant Force Fields via Feature-wise Linear Modulation
Samuel Sahel-Schackis, Ken-ichi Nomura, Aiichiro Nakano +2
Foundation machine learning force fields (MLFFs) such as MACE-MP-0 and UMA cover broad chemical space at near density functional theory (DFT) accuracy. However, they assume equilib…
X-ray Coherent Attosecond Pulse Pair Spectroscopy
Zain Abhari, Thomas M. Linker, Thomas Kroll +14
X-ray free electron laser (XFEL) experiments using self-amplified spontaneous emission (SASE) pulses typically achieve temporal resolutions of order several femtoseconds, as the pu…
Chiral Altermagnon in MnTe
Daniel Jost, Resham B. Regmi, Eder G. Lomeli +12
Altermagnetism has surfaced as a novel magnetic phase, bridging the properties of ferro- and anti-ferromagnetism. The momentum-dependent spin-splitting observed in these materials…
Experimental demonstration of attosecond hard X-ray pulses
Ichiro Inoue, River Robles, Aliaksei Halavanau +24
We present the first direct experimental confirmation of attosecond pulse generation in the hard X-ray regime with a free-electron laser. Our experiment is based on measurements of…
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…
