To do so, we employ the infinite time evolving block decimation (iTEBD) method, a tensor network based algorithm, which enables us to obtain a good approximation of the ground state of an infinite one-dimensional lattice. This method allows us to characterize the different phases and the transition between them5 p.application/pdfengcc-by-nc-nd (c) Vallès, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/Model de Bose-HubbardTransició de fase quànticaTreballs de fi de grauBose–Hubbard modelQuantum phase transitionBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
