Published in 2019 at "Annalen der Physik"

DOI: 10.1002/andp.201900193

Abstract: The coupled mechanical resonators (MRs) are the prominent candidate for studying macroscopic quantum coherence. The prerequisite for observing macroscopic mechanical coherence is cooling the MRs to their ground state. Here, a theoretical scheme is proposed… read more here.

Published in 2017 at "ChemPlusChem"

DOI: 10.1002/cplu.201700347

Abstract: A series of rigidified dyes with either dodecyloxy or piperidyl donors in combination with either malononitrile or barbiturate acceptors were synthesized. To analyze the influence of varying the donor (piperidyl vs. dodecyloxy), chromophore (mono-, bis-,… read more here.
