Interface energies in Ising spin glasses
arXiv:cond-mat/0209290 · doi:10.1103/PhysRevLett.90.127202
Abstract
The replica method has been used to calculate the interface free energy associated with the change from periodic to anti-periodic boundary conditions in finite-dimensional spin glasses. At mean-field level the interface free energy vanishes but after allowing for fluctuation effects, a non-zero interface free energy is obtained which is significantly different from numerical expectations.
