Luttinger theorem and imbalanced Fermi systems
The proof of the Luttinger theorem, which was originally given for a normal Fermi liquid with equal spin populations formally described by the exact many-body theory at zero temperature, is here extended to a...

Enhanced paraconductivity-like fluctuations in the radiofrequency spectra of ultracold Fermi atoms
Radiofrequency spectroscopy provides a microscopic probe of fermionic pairing in ultracold Fermi gases. Calculations now suggest that there is a one-to-one correspondence between the theory of these spectra an...
