Quantum engineering and detection of advanced radiation beams
Controlling and shaping radiation beams is fundamental for a better understanding of radiation-matter interaction and advancing experimental techniques for material characterization at high spatial resolution.In particular, the current trend in the miniatu ...
EPFL2023Hard X-ray helical dichroism of disordered molecular media
Majed Chergui, Oliviero Cannelli, Giulia Fulvia Mancini, Malte Oppermann, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Christian David, Jérôme Lacour
Chirality is a structural property of molecules lacking mirror symmetry that has strong implications in diverse fields, ranging from life sciences to materials science. Chirality-sensitive spectroscopic methods, such as circular dichroism, exhibit weak sig ...
NATURE PORTFOLIO2022Correlation between Optical Activity and the Helical Molecular Orbitals of Allene and Cumulenes
Helical frontier molecular orbitals (MOs) appear in disubstituted allenes and even-n cumulenes. Chiral molecules are optically active, but while these molecules are single-handed chiral, p-orbitals of both helicities are present. Here we computationally ex ...
AMER CHEMICAL SOC2020Probing Molecular Chirality by Orbital-Angular-Momentum-Carrying X-ray Pulses
A twisted X-ray beam with orbital angular momentum is employed in a theoretical study to probe molecular chirality. A nonlocal response description of the matter-field coupling is adopted to account for the field short wavelength and the structured spatial ...
