Revealing the topological nature of the bond order wave in a strongly correlated quantum system

In collaboration with our colleagues from ICFO in Barcelona, we theoretically investigate the topological properties of the bond order wave in the extended Fermi-Hubbard model. We find that in a finite sized system, a topological order in the bond order wave regime can be stabilized experimentally allowing for the preparation of topologically protected edge modes. We finally propose an experimental scheme for the implementation and detection of this particular quantum phase.

The American Physical Society’s high impact journal Physical Review X has chosen its favourite papers for its tenth anniversary. Among those chosen was the first observation of a dipolar supersolid from our group and the simultaneous observation at the University of Stuttgart.

Innizer Prize for Francesca Ferlaino

Francesca Ferlaino has been awarded the Cardinal Innitzer Prize for Natural Sciences 2021 last weekend in Vienna for her outstanding achievements in the field of ultracold quantum gases. Her pioneering work with lathanoid atoms has been internationally groundbreaking in this field.

Cardinal Christoph Schönborn awarded 26 scientists with the Cardinal Innitzer Prize at the Archbishop’s Palace in Vienna on Saturday. This year, due to the cancellation of last year’s award ceremony caused by the pandemic, the 2020 and 2021 prizes were awarded together. Named after Vienna Archbishop Cardinal Theodor Innitzer (1875-1955), the science prize is one of the most prestigious awards of its kind in Austria. It has been awarded by the Archdiocese of Vienna since 1962 and is supported by the Federal Ministry of Science, several provinces, as well as banks, insurance companies and the Chamber of Commerce. The list of laureates reads like a “who’s who” of Austrian science.

Francesca Ferlaino was awarded this year’s Cardinal Innitzer Prize for Natural Sciences for her pioneering work with ultracold quantum gases. Her work with lathanoid atoms was particularly highlighted. “As a scientist, you have made a difference when others jump on the bandwagon – nowadays, more and more physicists around the world are working with precisely these atoms. It is therefore no exaggeration to say that Ferlaino has done true pioneering work,” said laudator Ulrike Diebold from TU Wien.
