We pay special attention to the exact and uniform WKB methods. The double well potential is considered as a motivating example due to its physical modeling relevance. The first terms of the ground-state energy trans-series for this potential are calculated as a direct application of the uniform WKB method5 p.application/pdfengcc-by-nc-nd (c) Solé, 2019http://creativecommons.org/licenses/by-nc-nd/3.0/es/Teoria quànticaAproximació WKBTreballs de fi de grauQuantum theoryWKB approximationBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
