Louis defends his Masters’ thesis!
Louis held his successful defence for his Masters’ thesis this week! (and has his first paper published on the same day!) Louis will be staying on as a PhD student of the Erbium lab, here’s to the next 4 years!
Revealing the topological nature of the bond order wave in a strongly correlated quantum system
Now published in PRR with collaborators from ICFO, Barcelona! In the recent years, great effort has been devoted toward the study of symmetry-protected topological phases. We show that the bond order wave (BOW) induced by frustration between competing couplings has a nontrivial topological sector in the presence of chiral symmetry. We reveal its topological nature by finding a nonzero string order correlator and a degenerate entanglement spectrum, and design a realistic experimental scheme involving magnetic atoms trapped in an optical lattice. The latter paves the way towards an efficient quantum simulation of topological phases in many-body quantum systems.

Alex defends his thesis!
Alex held his defense for his PhD thesis last week and is now officially a Doctor of Philosophy. He’s moving to Canada next for a post-doc position! Congratulations and good luck!
Determination of the scattering length of erbium atoms
Now published in PRA with collaborators from JILA, Boulder (Colorado, USA), we accurately determine the scattering length for the four bosonic erbium isotopes with highest abundance in the magnetic field range from 0G to 5G. We use the cross-dimensional thermalization technique and extract the scattering length by applying a fit of the complete Enskog equations of change and by utilizing an analytic formula for the so-called number of collisions per re-thermalization. We benchmark our results with the very accurate but experimentally more demanding lattice modulation spectroscopy, confirming the accuracy of our experimental protocol.
