Time-domain extreme ultraviolet diffuse scattering spectroscopy of nanoscale surface phonons
F. Capotondi, A. Maznev, F. Bencivenga +18
We report the observation of dynamic fringe patterns in the diffuse scattering of extreme ultraviolet light from surfaces, following femtosecond optical excitation. At each point o…
Dimensionality reduction of optically generated vortex strings in a charge density wave
Sajal Dahal, Alex H. Miller, Viktor Krapivin +11
In phase transitions, mesoscale structures such as topological defects, vortex strings, and domain walls control the path towards equilibrium, and thus the functional properties of…
Nanoscale Ultrafast Lattice Modulation with Hard X-ray Free Electron Laser
Haoyuan Li, Nan Wang, Leon Zhang +24
Understanding and controlling microscopic dynamics across spatial and temporal scales has driven major progress in science and technology over the past several decades. While ultra…
Formalism to Image the Dynamics of Coherent and Incoherent Phonon with Dark-Field X-ray Microscopy using Kinematic Diffraction Theory
Darshan Chalise, Yifan Wang, Mariano Trigo +1
Dark-field X-ray microscopy (DFXM) is a novel X-ray imaging technique developed at synchrotrons to image along the diffracted beam with a real space resolution of ~100 nm and recip…
