The interface tension vanishes according to $\\sigma = \\sigma_0 (1 - T/T_c)^{\\mu}$ as the temperature T approaches the critical point from below. Similarly the correlation length diverges as $\\xi = f_- (1 - T/T_c)^{-\\nu}$ in the low temperature region. For three-dimensional systems the dimensionless product $R_- = \\sigma_0 f_-^2$ is universal. We calculate its value in the framework of field theory in d=3 dimensions by means of a saddle-point expansion around the kink solution"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/9708212","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
