Critical behavior of the three-dimensional Ising spin glass

The three-dimensional nearest-neighbor Ising spin-glass model with Gaussian bonds (〈${J}^{2}$〉=1) is studied numerically using the ``large-cell'' renormalization group. Estimates for the critical coupling and the thermal exponent are ${K}_{c}$=1/${T}_{c}$=1.2\ifmmode\pm\else\textpm\fi{}0.1 and ${y}_{t}$=1/\ensuremath{\nu}=0.30\ifmmode\pm\else\textpm\fi{}0.05, respectively.
