Collective nuclear excitation and pulse propagation in single-mode x-ray waveguides
Leon M. Lohse, Petar AndrejiÄ, Sven Velten +8
Waveguides offer a means to controllably couple atomic ensembles to the electromagnetic field therein. Here, we demonstrate x-ray propagation in planar thin-film waveguides coupled…
Skyrme-Hartree-Fock-BCS approach to Th and neighboring nuclei
Nikolay Minkov, Adriana Pálffy, Philippe Quentin +1
The microscopic origin of the Th isomer and its possible manifestation also in neighboring nuclei is explored within a selfconsistent Skyrme Hartree-Fock plus Bardeen-Coop…
Efficient production of Th via nuclear excitation by electron capture
Jingyan Zhao, Adriana Pálffy, Christoph H. Keitel +1
The nuclear isomeric state Th with an exceptionally low excitation energy makes the Th isotope a crucial candidate for nuclear clocks and many other applications.…
Neural-network-supported basis optimizer for the configuration interaction problem in quantum many-body clusters: Feasibility study and numerical proof
Pavlo Bilous, Louis Thirion, Henri Menke +3
A deep-learning approach to optimize the selection of Slater determinants in configuration interaction calculations for condensed-matter quantum many-body systems is developed. We…
Photoexcitation of the Th nuclear clock transition using twisted light
Tobias Kirschbaum, Thorsten Schumm, Adriana Pálffy
The Th nucleus has a unique transition at only 8 eV which could be used for a novel nuclear clock. We investigate theoretically the prospects of driving this transition wit…
