Sharp interaction estimates and their application: existence of normalized ground states to coupled Schrödinger systems with potentials

Yinbin Deng, Qihan He, Xuexiu Zhong

In this paper, our aim is to prove the existence of normalized ground state for the following Schrödinger systems with potentials $$\begin{cases} -Δu_1+V_1(x)u_1+λ_1 u_1=\partia…
