Pairing and radio-frequency spectroscopy in two-dimensional Fermi gases
Ville Pietilä
We theoretically study the normal phase properties of strongly interacting two-component Fermi gases in two spatial dimensions. In the limit of weak attraction, we find that the ga…

Fermi polarons in two dimensions
Richard Schmidt, Tilman Enss, Ville Pietilä +1
We theoretically analyze inverse radiofrequency (rf) spectroscopy experiments in two-component Fermi gases. We consider a small number of impurity atoms interacting strongly with a…

Phase transitions in dipolar spin-1 Bose gases
Ville Pietilä, Mikko Möttönen
We study phase transitions in homogeneous spin-1 Bose gases in the presence of long-range magnetic dipole-dipole interactions (DDI). We concentrate on three-dimensional geometries…
