An alternative approach to populate and study the Th nuclear clock isomer
M. Verlinde, S. Kraemer, J. Moens +24
A new approach to observe the radiative decay of the Th nuclear isomer, and to determine its energy and radiative lifetime, is presented. Situated at a uniquely low excitat…

Probing interacting two-level systems with rare-earth ions
Dapeng Ding, David van Driel, Lino M. C. Pereira +8
Two-level systems (TLS) in amorphous materials limit coherence times of a number of solid-state quantum devices. Interactions between TLS become prominent below 100 mK, but the cou…

Deposition and patterning of magnetic atom trap lattices in FePt films with periods down to 200nm
A. L. La Rooij, S. Couet, M. C. van der Krogt +3
We report on the epitaxial growth and the characterization of thin FePt films and the subsequent patterning of magnetic lattice structures. These structures can be used to trap ult…
