Finite momentum condensate with p-wave interaction

A system of “spin-½” bosons with p-wave interaction can be a promising candidate for realizing a fragmented Bose-Einstein condensate known as the KSA state. In this talk, I show that the KSA state has lower energy than the standard condensate states that is explored so far in literature. Furthermore, I investigate the elementary excitations of the KSA state. Importance of the role of effective range will be emphasized in the talk.
