60. Ultracold fermionic ytterbium with strong interactions in optical lattices

Simon Fölling (Ludwig-Maximilians-Universität and Max-Planck-Institut für Quantenoptik)

Invited talk

Using both internal degrees of freedeom of ytterbium, the nuclear spin as well as the electronic spin quantum number, allows to implement novel many-body systems in optical lattices. The interaction properties of yetterbium-173 have proven to be particularly intriguing, with a Feshbach resonance between the singlet and triplet states of the electronic degree of freedom, which we characterize...

20. Atom interferometry with ultra-cold strontium atoms

Dr Nicola Poli (Dipartimento di Fisica e Astronomia & LENS - Univ. Firenze)

Invited talk

In this talk I'll present the most recent results on a large momentum transfer (LMT) Mach-Zehnder atom interferometer with ultra-cold strontium atoms [Mazzoni2015]. LMT Bragg diffraction pulses (up to eight photon recoils) are applied to atoms in free fall, launched upward with an accelerated lattice. We then use the strontium interferometer as a gravimeter, demonstrating best...

43. Atom Interferometry with Group II Atoms for Gravitational Wave Detection

Jason Hogan (Stanford University)

Invited talk

The advent of gravitational wave astronomy promises to provide a new window into the universe. Low frequency gravitational waves below 10 Hz are expected to offer rich science opportunities both in astrophysics and cosmology, complementary to signals in LIGO’s band. Detector designs based on atom interferometry have a number of advantages over traditional approaches in this band, including...
