Quantitative analysis of ground states for the fractional logarithmic Schrödinger equation

Let $N\geq1$ and $0<s<1$. We study positive ground states of the fractional logarithmic Schrödinger equation \begin{equation*} (-Δ)^sQ=Q\log Q \quad\text{in }\mathbb{R}^N. \end{equation*} We prove that for every $N\geq1$ and $0<s<1$, the positive ground state is unique up to translations and nondege
