Title: Dislocations And Melting In Two Dimensions: The Critical Region
Author: Greif J.M.

Abstract: A new analysis is presented of the critical-point behavior of two-dimensional melting in the Kosterlitz-Thouless-Nelson-Halperin-Young theory. The analysis confirms the Kosterlitz-Thouless-Nelson-Halperin-Young critical-point exponent, 1/2»=0.36963, but also gives a criterion for its own range of validity amounting to t<<10-3, where t is the reduced temperature. Both results are confirmed by direct numerical computation, and it is shown that the corresponding range of correlation lengths is 3/4+>>1013 lattice spacings. The implications of these results for experimental verification are discussed. © 1982 The American Physical Society.
