Time-dependent correlations of the Edwards-Anderson order parameter above the spin-glass transition
Jingjin Song, Sheena K. K. Patel, Rupak Bhattacharya +11
In 1975 Edwards and Anderson introduced a new paradigm that interacting quenched systems, such as a spin-glass, have a phase transition in which long time memory of spatial pattern…
Critical slowing of the spin and charge density wave order in thin film Cr following photoexcitation
Sheena K. K. Patel, Oleg Yu. Gorobtsov, Devin Cela +11
We report on the evolution of the charge density wave (CDW) and spin density wave (SDW) order of a chromium film following photoexcitation with an ultrafast optical laser pulse. Th…
Skyrmion-Excited Spin Wave Fractal Network
Nan Tang, W. L. N. C. Liyanage, Sergio A. Montoya +9
Magnetic skyrmions exhibit unique, technologically relevant pseudo-particle behaviors which arise from their topological protection, including well-defined, three-dimensional dynam…
Megahertz-rate Ultrafast X-ray Scattering and Holographic Imaging at the European XFEL
Nanna Zhou Hagström, Michael Schneider, Nico Kerber +97
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, from chemistry to biology, giving researchers acce…
Phonon-assisted formation of an itinerant electronic density wave
Jiaruo Li, Oleg Yu. Gorobtsov, Sheena K. K. Patel +13
Electronic instabilities drive ordering transitions in condensed matter. Despite many advances in the microscopic understanding of the ordered states, a more nuanced and profound q…
Femtosecond Photocurrents at the Pt/FeRh Interface
Rajasekhar Medapalli, Guanqiao Li, Sheena K. K. Patel +4
Femtosecond laser excitation of FeRh/Pt bilayers launches an ultrafast pulse of electric photocurrent in the Pt-layer and thus results in emission of electromagnetic radiation in t…
Direct measurement of temporal correlations above the spin-glass transition by coherent resonant magnetic x-ray spectroscopy
Jingjin Song, Sheena K. K. Patel, Rupak Bhattacharya +9
In the 1970s a new paradigm was introduced that interacting quenched systems, such as a spin-glass, have a phase transition in which long time memory of spatial patterns is realize…
Ultrafast perturbation of magnetic domains by optical pumping in a ferromagnetic multilayer
Dmitriy Zusin, Ezio Iacocca, Loïc Le Guyader +23
Ultrafast optical pumping of spatially nonuniform magnetic textures is known to induce far-from-equilibrium spin transport effects. Here, we use ultrafast x-ray diffraction with un…
Laser induced phase transition in epitaxial FeRh layers studied by pump-probe valence band photoemission
Federico Pressacco, Vojtěch Uhlíř, Matteo Gatti +7
We use time-resolved X-ray photoelectron spectroscopy to probe the electronic and magnetization dynamics in FeRh films after ultrafast laser excitations. We present experimental an…
Photoinduced Enhancement of the Charge Density Wave Amplitude
A. Singer, S. K. K. Patel, R. Kukreja +14
Symmetry breaking and the emergence of order is one of the most fascinating phenomena in condensed matter physics. It leads to a plethora of intriguing ground states found in antif…
