Glitches in supersolids: links between neutron stars and quantum matter

Glitches in supersolids: links between neutron stars and quantum matter

By emulating the connection between a rotating supersolid phase and an external solid phase, we were able to replicate “glitches” – sudden jumps in the solid angular momentum driven by quantum vortices leaving the supersolid.

In the T-REQS lab we have now loaded atoms in our optical tweezers.

Vortices in a dysprosium gas

Vortices in a dysprosium gas

By stirring the magnetic field which polarizes the atoms in a dysprosium condensate, we were able to generate vortices–tiny quantum tornadoes–in a dipolar gas for the first time!

Bloch Oscillations

Bloch Oscillations

By letting an erbium quantum droplet fall under gravity through an optical lattice, it is possible to understand the inter-atomic interactions and quantum fluctuations through variations of the Bloch oscillation.

Phase coherence in out-of-equilibrium supersolid states of ultracold dipolar atoms

Phase coherence in out-of-equilibrium supersolid states of ultracold dipolar atoms

By quenching the contact interaction, it is possible to destroy the phase coherence in a dipolar supersolid. However, the supersolidity is “repaired” when reversing the dephasing process.  

Our group studies dipolar quantum gases made of  Erbium (Er) and Dysprosium (Dy) atoms. These extraordinarily magnetic species are a powerful new resource for reaching quantum simulation with strong connectivity, in which each atom is coupled to the other over long distances, and exploring exotic phases of matter that have no classical counterpart.

We have three labs: the ERBIUM LAB, where Er was Bose condensed for the first time ever, the Er-Dy LAB which studies quantum dipolar mixtures under a quantum-gas microscope, and the T-Reqs LAB, where we trap Er atoms in arrays of optical tweezers for Rydberg physics. Recently, we have established a theoretical subdivision aimed at studying and predicting dipolar phenomena in dipolar quantum gases and mixtures.

The group, led by Francesca Ferlaino, is jointly located at the  Institute for Experimental Physics (IExP) of the University of Innsbruck and at the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences, and it is part of  the Innsbruck Center for Ultracold Atoms and Quantum Gases
