Abstract
In this paper, we investigate normalized solutions for the Chern–Simons–Schrödinger system with a trapping potential \(V(x)=\omega |x|^{2}\) and a exponential critical growth f(u). The solutions correspond to critical points of the underlying energy functional subject to the \(L^{2}\)-norm constraint, namely, \(\int _{\mathbb {R}^{2}}|u|^{2}dx=c\) for \(c>0\) given. Under some suitable assumptions on f, we show that the system has at least two normalized solutions \(u_{c},\hat{u}_{c}\in H^{1}(\mathbb {R}^{2})\), depending on the trapping frequency \(\omega \) and the mass c, where \(u_{c}\) is a ground state with positive energy and orbitally stable, while \(\hat{u} _{c}\) is a high-energy solution with positive energy. In addition, the asymptotic behavior of the solution \(u_{c}\) as \(c\rightarrow 0\) is described.
