We study the constraint minimization problem related to the Gross–Pitaevskii functional with a higher order interaction
I a δ : = inf E a δ ( ϕ ) : ϕ H ( R 2 ) , ϕ L 2 2 = 1 ,
where δ>0,a>0,
E a δ ( ϕ ) : = R 2 | ϕ | 2 d x + R 2 V | ϕ | 2 d x + δ 2 R 2 | ( | ϕ | 2 ) | 2 d x a 2 R 2 | ϕ | 4 d x
and V is a continuous periodic potential. Thanks to the concentration‐compactness principle, we show the existence of minimizers for I a δ with a a * : = Q L 2 2 and δ sufficiently small, where Q is the unique positive radial solution to
Δ Q + Q Q 3 = 0 .
The blow‐up behaviors of minimizers for I a δ as δ↘0 are described in details with an additional assumption on the external potential in the case a=a*.
