%0 Journal Article %T Study of +/-J Ising Spin Glasses via Multicanonical Ensemble %A Tarik Celik %A Ulrich H. E. Hansmann %A Bernd Berg %J Physics %D 1993 %I arXiv %X We performed numerical simulations of 2D and 3D Edwards-Anderson spin glass models by using the recently developed multicanonical ensemble. Our ergodicity times increase with the lattice size approximately as $V^3$. The energy, entropy and other physical quantities are easily calculable at all temperatures from a single simulation. Their finite size scalings and the zero temperature limits are also explored. %U http://arxiv.org/abs/cond-mat/9303025v1
