Understanding Josephson tunneling in strongly interacting Fermi superfluids in the simplest way!

Print

Together with Wilhelm Zwerger, we developed a simple analytic model to quantitatively describe the Josephson tunneling between two Fermi superfluids along the entire BCS-BEC crossover. Our work just got published in Phys. Rev. A.
