| Outline of Final Research Achievements |
I have theoretically investigated a possible idea to realize a p-wave superfluid Fermi atomic gas, starting from the s-wave superfluid phase with a synthetic anti-symmetric spin-orbit interaction. I clarified what type of p-wave pair amplitude is induced by various kinds of spin-orbit couplings. I also confirmed that the superfluid phase transition temperature where large p-wave pair amplitude is induced is accessible within the current experimental technology. Using the induced p-wave pair amplitude in an s-wave superfluid Fermi gas, I showed that, when one suddenly changes the symmetry of pairing interaction from the s-wave one to a p-wave one, one can immediately realize a p-wave superfluid state.
