Chiral rotational dynamics in the molecular frame: Breaking symmetry with angular momentum
Alexander Blech, Monika Leibscher, Christiane P. Koch
Achiral molecules can be prepared in superposition states that are chiral. Here, we propose angular momentum orientation in the molecular frame to achieve the required symmetry bre…
Interference between multiple photoionization pathways in chiral molecules: Converging continuum results in Gaussian bases
Muhammad Sakhi, Alexander Blech, Corbin Allison +2
An accurate description of photoionization observables is a central challenge for theoretical models of molecular photoionization. Within standard electronic-structure approaches,…
Effects of realistic pulse shapes in two-dimensional spectroscopy
M. Russo, R. Gilliot, A. Blech +3
Two-dimensional (2D) spectroscopy is a powerful pump-pump-probe technique for revealing couplings between quantum states and disentangling the different contributions to the optica…
Attosecond Control and Measurement of Chiral Photoionisation Dynamics
Meng Han, Jia-Bao Ji, Alexander Blech +5
Many chirality-sensitive light-matter interactions are governed by chiral electron dynamics. Therefore, the development of advanced technologies harnessing chiral phenomena would c…
Sympathetic rotational cooling of large trapped molecular ions
Monika Leibscher, Alexander Blech, Christiane P. Koch
We suggest a protocol for the sympathetic cooling of a molecular asymmetric top rotor co-trapped with laser-cooled atomic ions, based on resonant coupling between the molecular ion…
Numerical evaluation of orientation averages and its application to molecular physics
Alexander Blech, Raoul M. M. Ebeling, Marec Heger +2
In molecular physics, it is often necessary to average over the orientation of molecules when calculating observables, in particular when modelling experiments in the liquid or gas…
Quantum control of ro-vibrational dynamics and application to light-induced molecular chirality
Monika Leibscher, Eugenio Pozzoli, Alexander Blech +3
Achiral molecules can be made temporarily chiral by excitation with electric fields, in the sense that an average over molecular orientations displays a net chiral signal [Tikhonov…
Fano interference in quantum resonances from angle-resolved elastic scattering
Prerna Paliwal, Alexander Blech, Christiane P. Koch +1
Asymmetric spectral line shapes are a hallmark of interference of a quasi-bound state with a continuum of states. Such line shapes are well known for multichannel systems, for exam…
Continuum-electron interferometry for enhancement of photoelectron circular dichroism and measurement of bound, free, and mixed contributions to chiral response
R. Esteban Goetz, Alexander Blech, Corbin Allison +2
We develop photoelectron interferometry based on laser-assisted extreme ultraviolet ionization for flexible and robust control of photoelectron circular dichroism in randomly orien…
Phase protection of Fano-Feshbach resonances
Alexander Blech, Yuval Shagam, Nicolas Hölsch +8
Decay of bound states due to coupling with free particle states is a general phenomenon occurring at energy scales from MeV in nuclear physics to peV in ultracold atomic gases. Suc…
