Ground States of Fermionic Nonlinear Schrödinger Systems with Coulomb Potential II: The $L^2$-Critical Case

Bin Chen, Yujin Guo, Shu Zhang

As a continuation of \cite{me}, we consider ground states of the $N$ coupled fermionic nonlinear Schrödinger system with a parameter $a$ and the Coulomb potential $V(x)$ in the $L…
