We begin by analysing the area law behaviour of entanglement entropy and its logarithmic violation at the critical point. Next, we introduce the classical-to-quantum correspondence to elucidate the structure of two-point correlation functions. Finally, we characterize the distinct phases of the model via its entanglement spectrum6 p.application/pdfengcc-by-nc-nd (c) Giménez, 2025http://creativecommons.org/licenses/by-nc-nd/3.0/es/Teoria quànticaEntrellaçament quànticTreballs de fi de grauQuantum theoryQuantum entanglementBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
