## Quantum phase diagram of Rydberg-Dressed Fermi Gases    [PDF]

Bo Xiong, H. H. Jen, Daw-Wei Wang
We theoretically investigate the p-wave superfluid phase of a single component Fermi gases, where the interatomic interaction is generated by weakly coupled to a Rydberg state. By self-consistently solving the gap equation and comparing the total free energy, three quantum phases can be observed: polar ($p_{z}$), axial ($p_{x}+ip_{y}$), and axi-planar ($p_{x}+i\beta_{p}p_{y}$) phases, where the later is due to the finite-range interaction from blockade effects. We further qualitatively explain the phase diagram based on the Ginzburg-Landau theory. The critical temperature for the p-wave superfluid pairing can easily achieve $0.1E_{F}$ under the current experimental condition. The Rydberg-dressed Fermi gases provides very important system to the studies of topological superfluid compared with traditional $^{3}$He system.
