Numerical Study of Spin and Chiral Order in a Two-Dimensional XY Spin Glass
J. M. Kosterlitz, N. Akino
Abstract
The two dimensional XY spin glass is studied numerically by a finite size scaling method at T=0 in the vortex representation which allows us to compute the exact (in principle) spin and chiral domain wall energies. We confirm earlier predictions that there is no glass phase at any finite T. Our results strongly support the conjecture that both spin and chiral order have the same correlation length exponent ν≈ 2.70. We obtain preliminary results in 3d.
