We report a high-precision finite-size scaling study of the critical behavior of the three-dimensional Ising Edwards-Anderson model (the Ising spin glass).

Standard (hyper)scaling relations yield α=-5.69(13), β=0.782(10), and γ=6.13(11). We also compute several universal quantities at Tc. © 2013 American Physical Society.

Abstract
We report a high-precision finite-size scaling study of the critical behavior of the three-dimensional Ising Edwards-Anderson model (the Ising spin glass). We have thermalized lattices up to L=40 using the Janus dedicated computer. Our analysis takes into account leading-order corrections to scaling. We obtain Tc=1.1019(29) for the critical temperature, ν=2.562(42) for the thermal exponent, η=-0.3900(36) for the anomalous dimension, and ω=1.12(10) for the exponent of the leading corrections to scaling. Standard (hyper)scaling relations yield α=-5.69(13), β=0.782(10), and γ=6.13(11). We also compute several universal quantities at Tc. © 2013 American Physical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
