  "abstract": "We prove that more than nine percent of the central values $L(\\frac{1}{2},\\chi_p)$ are non-zero, where $p\\equiv 1 \\pmod{8}$ ranges over primes and $\\chi_p$ is the real primitive Dirichlet character of conductor $p$. Previously, it was not known whether a positive proportion of these central values are non-zero. As a by-product, we obtain the order of magnitude of the second moment of $L(\\frac{1}{2},\\chi_p)$, and conditionally we obtain the order of magnitude of the third moment. Assuming the Generalized Riemann Hypothesis, we show that our lower bound for the second moment is asymptotically sharp.",
