Fate of dissipative hierarchy of timescales in the presence of unitary dynamics
Nick D. Hartmann, Jimin L. Li, David J. Luitz
The generic behavior of purely dissipative open quantum many-body systems with local dissipation processes can be investigated using random matrix theory, revealing a hierarchy of…
Applying Bayesian Inference and deterministic anisotropy to retrieve the molecular structure distribution from gas-phase diffraction experiments
Kareem Hegazy, Varun Makhija, Phil Bucksbaum +12
Currently, our general approach to retrieving molecular structures from ultrafast gas-phase diffraction heavily relies on complex ab initio electronic or vibrational excited state…
Site-specific Interrogation of an Ionic Chiral Fragment During Photolysis Using an X-ray Free-Electron Laser
Markus Ilchen, Philipp Schmidt, Nikolay M. Novikovskiy +24
Short-wavelength free-electron lasers with their ultrashort pulses at high intensities have originated new approaches for tracking molecular dynamics from the vista of specific sit…
A self-referenced in-situ arrival time monitor for X-ray free-electron lasers
Michael Diez, Andreas Galler, Sebastian Schulz +11
We present a novel, highly versatile, and self-referenced arrival time monitor for measuring the femtosecond time delay between a hard X-ray pulse from a free-electron laser and an…
Machine learning applied to single-shot x-ray diagnostics in an XFEL
A. Sanchez-Gonzalez, P. Micaelli, C. Olivier +39
X-ray free-electron lasers (XFELs) are the only sources currently able to produce bright few-fs pulses with tunable photon energies from 100 eV to more than 10 keV. Due to the stoc…
Diffractive Imaging of Coherent Nuclear Motion in Isolated Molecules
Jie Yang, Markus Guehr, Xiaozhe Shen +17
Observing the motion of the nuclear wavepackets during a molecular reaction, in both space and time, is crucial for understanding and controlling the outcome of photoinduced chemic…
Beyond a phenomenological description of magnetostriction
A. H. Reid, X. Shen, P. Maldonado +28
We use ultrafast x-ray and electron diffraction to disentangle spin-lattice coupling of granular FePt in the time domain. The reduced dimensionality of single-crystalline FePt nano…
Direct measurement of non-equilibrium phonon occupations in femtosecond laser heated Au films
T. Chase, M. Trigo, A. H. Reid +9
We use ultrafast electron diffraction to detect the temporal evolution of phonon populations in femtosecond laser-excited ultrathin single-crystalline gold films. From the time-dep…
Diffractive imaging of a molecular rotational wavepacket with femtosecond Megaelectronvolt electron pulses
Jie Yang, Markus Guehr, Theodore Vecchione +20
Imaging changes in molecular geometries on their natural femtosecond timescale with sub-Angstrom spatial precision is one of the critical challenges in the chemical sciences, since…
