Existence and concentration of ground state solution to a nonlocal Schr\"{o}dinger equation

We study a class of Schr\"{o}dinger-Kirchhoff system involving critical exponent. We aim to find suitable conditions to assure the existence of a positive ground state solution of Nehari-Poho\u{z}aev type $u_{\varepsilon}$ with exponential decay at infinity for $\varepsilon$ and $u_{\varepsilon}$ concentrates around a global minimum point of $V$ as $\varepsilon\rightarrow0^{+}.$ The nonlinear term includes the nonlinearity $f(u)\sim|u|^{p-1}u$ for the well-studied case $p\in[3,5)$, and the less-studied case $p\in(2,3)$.
