Infrared-induced ultrafast melting of nanostructured platinum films probed by an X-ray free-electron laser
Luca Gelisio, Young Yong Kim, Seon Woo Lim +10
Understanding melting in metals is a hot topic of present research. This may be accomplished by pumping the system with infrared (IR) laser radiation, and probing it with hard X-ra…
Melting Domain Size and Recrystallization Dynamics of Ice Revealed by Time-Resolved X-ray Scattering
Cheolhee Yang, Marjorie Ladd-Parada, Kyeongmin Nam +13
The phase transition between water and ice is ubiquitous and one of the most important phenomena in nature. Here, we performed time-resolved x-ray scattering experiments capturing…
Optically Induced Picosecond Lattice Compression in the Dielectric Component of a Strongly Coupled Ferroelectric/Dielectric Superlattice
Deepankar Sri Gyan, Hyeon Jun Lee, Youngjun Ahn +13
Above-bandgap femtosecond optical excitation of a ferroelectric/dielectric BaTiO3/CaTiO3 superlattice leads to structural responses that are a consequence of the screening of the s…
X-ray Free Electron Laser Studies of Electron and Phonon Dynamics of Graphene Adsorbed on Copper
Hirohito Ogasawara, Han Wang, Jörgen Gladh +23
We report optical pumping and X-ray absorption spectroscopy experiments at the PAL free electron laser that directly probe the electron dynamics of a graphene monolayer adsorbed on…
Characterization of photoinduced normal state through charge density wave in superconducting YBaCuO
H. Jang, S. Song, T. Kihara +17
The normal state of high-Tc cuprates has been considered one of the essential topics in high-temperature superconductivity research. However, compared to the high magnetic fields s…
Optical excitation of electromagnons in hexaferrite
Hiroki Ueda, Hoyoung Jang, Sae Hwan Chun +11
Understanding ultrafast magnetization dynamics on the microscopic level is of strong current interest due to the potential for applications in information storage. In recent years,…
4D visualization of the photoexcited coherent magnon by an X-ray free electron laser
Hoyoung Jang, Hiroki Ueda, Hyeong-Do Kim +12
X-ray free electron lasers (XFEL) create femtosecond X-ray pulses with high brightness and high longitudinal coherence allowing to extend X-ray spectroscopy and scattering techniqu…
Ultrafast renormalization of the onsite Coulomb repulsion in a cuprate superconductor
Denitsa R. Baykusheva, Hoyoung Jang, Ali A. Husain +14
Ultrafast lasers are an increasingly important tool to control and stabilize emergent phases in quantum materials. Among a variety of possible excitation protocols, a particularly…
Time-resolved resonant elastic soft X-ray scattering at Pohang Accelerator Laboratory X-ray Free Electron Laser
Hoyoung Jang, Hyeong-Do Kim, Minseok Kim +31
Resonant elastic X-ray scattering has been widely employed for exploring complex electronic ordering phenomena, like charge, spin, and orbital order, in particular in strongly corr…
