Disentangling spin polarization from driven circular ionic motion in EuTiO
Clifford J. Allington, Matthew J. Lutz, Enoch +31
Coherently driven circular ionic motion has been reported to produce large helicity-dependent optical responses attributed to transient magnetization. However, the microscopic natu…
Tuning chirality amplitude at ultrafast timescales
Hiroki Ueda, Takahiro Sato, Quynh L. Nguyen +12
Chirality is a fundamental symmetry concept describing discrete states, i.e., left-handed, right-handed, or achiral, and existing at disparate scales and in many categories of scie…
Chiral phonons in polar LiNbO3
Hiroki Ueda, Abhishek Nag, Carl P. Romao +3
Quasiparticles describe collective excitations in many-body systems, and their symmetry classification is of fundamental importance because they govern physical processes on variou…
Circular dichroism in resonant inelastic x-ray scattering from birefringence in CuO
Abhishek Nag, Gérard Sylvester Perren, Hiroki Ueda +6
Resonant inelastic x-ray scattering (RIXS) has become a prominent technique to study quasiparticle excitations. With advances in polarization analysis capabilities at different fac…
Non-chiral 1T-TiSe2 creates circular dichroism in resonant X-ray diffraction via multipole scattering interference
Hiroki Ueda, Yves Joly, Urs Staub
Resonant X-ray diffraction (RXD) provides a unique capability to investigate electronically ordered states in matter. Importantly, circular dichroism in RXD can determine the absol…
Element-specific, non-destructive profiling of layered heterostructures
Nicolò D'Anna, Jamie Bragg, Elizabeth Skoropata +16
Fabrication of semiconductor heterostructures is now so precise that metrology has become a key challenge for progress in science and applications. It is now relatively straightfor…
4 electron temperature driven ultrafast electron localization
Kohei Yamagami, Hiroki Ueda, Urs Staub +9
Valence transitions in strongly correlated electron systems are caused by orbital hybridization and Coulomb interactions between localized and delocalized electrons. The transition…
Non-equilibrium dynamics of spin-lattice coupling
Hiroki Ueda, Roman Mankowsky, Eugenio Paris +18
Interactions between the different degrees of freedom form the basis of many manifestations of intriguing physics in condensed matter. In this respect, quantifying the dynamics of…
Ultrafast transient increase of oxygen octahedral rotations in a perovskite
M. Porer, M. Fechner, M. Kubli +13
The ability to control the structure of a crystalline solid on ultrafast timescales bears enormous potential for information storage and manipulation or generating new functional s…
The Ultrafast Einstein-De Haas Effect
Christian Dornes, Yves Acremann, Matteo Savoini +20
The original observation of the Einstein-de Haas effect was a landmark experiment in the early history of modern physics that illustrates the relationship between magnetism and ang…
Magnetic properties of strained multiferroic CoCr2O4: a soft X-ray study
Y. W. Windsor, C. Piamonteze, M. Ramakrishnan +8
Using resonant soft X-ray techniques we follow the magnetic behavior of a strained epitaxial film of CoCr2O4, a type-II multiferroic. The film is [110]-oriented, such that both the…
Coherent Acoustic Perturbation of Second-Harmonic-Generation in NiO
L. Huber, A. Ferrer, T. Kubacka +14
We investigate the structural and magnetic origins of the unusual ultrafast second-harmonicgeneration (SHG) response of femtosecond-laser-excited nickel oxide (NiO) previously attr…
Ultrafast structural dynamics of the Fe-pnictide parent compound BaFe2As2
L. Rettig, S. O. Mariager, A. Ferrer +8
Using femtosecond time-resolved x-ray diffraction we investigate the structural dynamics of the coherently excited A1g phonon mode in the Fe-pnictide parent compound BaFe2As2. The…
