Kavli Affiliate: Michael D. Gladders | First 5 Authors: Kate Napier, Keren Sharon, Håkon Dahle, Matthew Bayliss, Michael D. Gladders | Summary: Tension between cosmic microwave background-based and distance ladder-based determinations of the Hubble constant ${rm H}_{rm 0}$ motivates pursuit of independent methods that are not subject to the same systematic effects. A promising alternative, […]

Kavli Affiliate: Simon Groblacher | First 5 Authors: Thomas Luschmann, Alexander Jung, Stephan Geprägs, Franz X. Haslbeck, Achim Marx | Summary: Lithium niobate (LNO) is a well established material for surface acoustic wave (SAW) devices including resonators, delay lines and filters. Recently, multi-layer substrates based on LNO thin films have become commercially available. Here, we […]
