Dong-Hee Kim (GIST) Fermion pairing turns out to be a less clear phenomenon than one might expect from the standard BCS theory. The possibility of an exotic type of superconductivity, including in particular the coexistence of magnetism and fermion pairing, has been argued for a long time in many fields of physics ranging from condensed matter physics to astrophysics and nuclear physics. In this talk, I will briefly review a new trend to approach this issue of exotic superconductivity using the system of ultracold atomic gases, a remarkable tool for playing with quantum many-body models. I will introduce our recent research results on the exotic paired state and the numerical methods that we have been employing for the ultracold atomic gas studies. |
