Since the realization of the first dipolar Bose–Einstein condensate (BEC) of strongly magnetic atoms, long-range and anisotropic dipole–dipole interactions have enabled the emergence of novel quantum phases driven by interaction-induced density modulations. Among these, the most remarkable is the supersolid phase, which simultaneously combines crystalline order with global phase coherence. In...

Neutron stars are the collapsed cores of massive stars that have undergone a supernova explosion. They are the densest known astrophysical objects, with a mass typically 1.4 times that of the Sun compressed into a radius of approximately 10 km. Deep within the star, where the density exceeds the nuclear equilibrium density, neutrons become superfluid and protons become superconducting. As a...

18. Vortex Pinning, 2D Turbulence, and Vorticity Avalanches in Nanoconfined Helium-4

I will present work that investigates the dynamics of quantized vortices in superfluid $^4$He confined to nanoscale geometries, where vortex motion is strongly influenced by pinning on disordered substrate surfaces. We present a numerical model for quasi-2D geometries that captures vortex-surface interactions as a velocity-dependent mutual friction; results from our numerical simulations show...
