Instanton theory and fluctuation corrections to the thermal nucleation rate of a ferromagnetic superfluid
Enrique Rozas Garcia, Johannes Hofmann
We provide a field-theoretical description of thermal nucleation in a one-dimensional ferromagnetic superfluid, a quantum-gas analogue of false-vacuum decay. The rate at which grou…

Probing Fractional Quantum Hall states in weakly interacting Fermi gases
Viktor Bekassy, Mikael Fogelström, Johannes Hofmann
Quantum gases are used to simulate the physics of the lowest Landau level (LLL) with neutral atoms, which in the simplest setup is achieved by rotating the gas at the confining har…
