Farewell to Alex Patscheider who has been with us since nearly the beginning of the Erbium and Er-Dy labs! Alex did his Masters’ in the Er-Dy labs before moving for his PhD into the Erbium lab, and will be sorely missed by the whole group! Best of luck for the new adventures in Canada 🇨🇦!
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 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!
