Condensed Matter Theory

Abstract:

An interface in the three-dimensional Blume-Capel model is studied using low-temperature series and mean-field theory. By calculating the leading-order diagrams in the low-temperature series expansion to all orders using a transfer matrix technique, the authors are able to show that the interface wets through an infinite sequence of layering transitions which become quasicontinuous as the bulk phase boundary is approached. The mean-field approximation agrees well with the low-temperature series results.
