Chiral phonons probed by X rays
Hiroki Ueda, Mirian García-Fernández, Stefano Agrestini +5
The concept of chirality is of great relevance in nature, from chiral molecules such as sugar to parity transformations in particle physics. In condensed matter physics, recent stu…
Antiferromagnetic spin canting and Magnetoelectric Multipoles in h-YMnO
M. Ramakrishnan, Y. Joly, Q. N. Meier +7
Hexagonal YMnO is a prototype antiferromagnet which exhibits multiferroic behavior with the ferroelectric and magnetic transitions occurring at different temperatures. We obs…
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 electron localization in a correlated metal
Jose R. L. Mardegan, Serhane Zerdane, Giulia Mancini +27
Ultrafast electron delocalization induced by a fs laser pulse is a well-known process and is the initial step for important applications such as fragmentation of molecules or laser…
Field-induced double spin spiral in a frustrated chiral magnet
M. Ramakrishnan, E. Constable, A. Cano +14
We report the direct observation of a magnetic-feld induced long-wavelength spin spiral modulation in the chiral compound Ba3TaFe3Si2O14. This new spin texture emerges out of a chi…
