We show numer-ically and describe semi-analytically that there is a one-to-one corre-spondence between them, with some corrections due to the differentsize between interacting and non-interacting energy spectra. This re-markable result holds both for the TBRI model with finite number ofbosons, and for the model originated from the celebrated Lieb-Liniger(LL) model".pdfengCIENCIAS FÍSICO MATEMÁTICAS Y CIENCIAS DE LA TIERRAEntropía--MatemáticasMecánica estadísticaTermodinámicaTesis de doctoradoopenAccessModelo de Lieb-Liniger
