It also studies the concept of photon as an excitation of the field and some of its properties. Finally, the results are applied to construct states of definite total angular momentum and the study of coherent states of the electromagnetic field.5 p.application/pdfengcc-by-nc-nd (c) Sala, 2017http://creativecommons.org/licenses/by-nc-nd/3.0/es/Camps electromagnèticsTeoria quànticaTreballs de fi de grauElectromagnetic fieldsQuantum theoryBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
