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…
