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…
Semimetallic Nature and Magnetic Polarons in EuB6 Studied by Angle-Resolved Photoemission Spectroscopy
Chul-Hee Min, Boyoun Kang, Beong Ki Cho +3
Temperature-dependent angle-resolved photoemission spectroscopy (ARPES) was carried out on single-crystalline EuB6 samples. By measuring ARPES spectra in an extended Brillouin zone…
