Ground States of Fermionic Nonlinear Schrödinger Systems with Coulomb Potential II: The $L^2$-Critical Case
As a continuation of \cite{me}, we consider ground states of the $N$ coupled
fermionic nonlinear Schr\"{o}dinger system with a parameter $a $ and the
Coulomb potential $V(x)$ in the $L^2$-critical case, where $a>0$ represents the
attractive strength of the quantum particles. For any given $N\in\mathbb{N}^+$,
we prove that the system admits ground states, if and only if the attractive
strength $a$ satisfies $0
