The Joint Condensed Matter Seminar (JCMS) series is organised by KTH Royal Insitute of Technology, Nordita, and Stockholm University.
On Friday, May 23rd, 2025 from 13.30 am to 14.30 we will host a seminar by Thomas Bland from Lund University.
The virtues of ultracold dipolar atoms: topological superconductivity to mean-field supersolidity
When combined with the high controllability of ultracold atomic systems, the long-range and anisotropic dipole-dipole interaction opens the door to a plethora of fascinating and novel phenomena. At the mean-field level, thousands of atoms can spontaneously coalesce into a state that is both superfluid and solid simultaneously–a state known as a supersolid. I will highlight recent theoretical advances in understanding the roles of the constituent solid and superfluid parts in this state, and highlight recent experimental confirmations of these predictions. In the many-body limit, ultracold magnetic atoms in optical lattices offer a versatile platform for exploring strongly correlated quantum phases. Through analytical and numerical analysis, I will present recent results that reveal a rich phase diagram featuring distinct superconducting and symmetry-protected topological phases.
