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 … Keep Reading…

THEORY GROUP

In our theory group, we utilise state-of-the-art methods to model the experiments of the ERBIUM and Er-Dy LABs, and provide assistance in guiding future experiments into the exciting phenomena not yet explored in dipolar quantum gases. The first major project of the theory group was to understand two-dimensional supersolidity, and we developed variational methods to investigate ideal scenarios moving from one- to two-dimensional droplet arrays, and new finite temperature theory to investigate evaporative cooling directly into the supersolid phase. This led to the first observation of a 2D supersolid in a circular trap. With the erbium lab, we recently developed a discrete-one-dimensional model for strongly dipolar gases in a 1D lattice, elucidating new droplet and soliton phases in this system, explaining the observations from the erbium experiment.

Most recently, our focus has been on the study of two-component dipolar systems, and the nature of supersolidity in these systems, and relating the supersolid phase expected in neutron stars to the ones producible in the Ferlaino labs!
