We check numerically the accuracy of our proposal and conjecture a formula for the asymptotic behavior of principal submatrices of a Toeplitz matrix. 000060832 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E24-2$$9info:eu-repo/grantAgreement/ES/FPI/C070-2014$$9info:eu-repo/grantAgreement/ES/MINECO/FPA2012-35453 000060832 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000060832 590__ $$a2.808$$b2014 000060832 591__ $$aOPTICS$$b16 / 86 = 0.186$$c2014$$dQ1$$eT1 000060832 591__ $$aPHYSICS, ATOMIC, MOLECULAR & CHEMICAL$$b9 / 34 = 0.265$$c2014$$dQ2$$eT1 000060832 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000060832 700__ $$0(orcid)0000-0001-7715-4970$$aEsteve, J.G.$$uUniversidad de Zaragoza 000060832 700__ $$aFalceto, Fernando 000060832 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDepartamento de Física Teórica$$cFísica Teórica 000060832 773__ $$g90 (2014), 062321 [8 pp]$$pPhys. rev., A$$tPHYSICAL REVIEW A$$x1050-2947 000060832 8564_ $$s834066$$uhttps://zaguan.unizar.es/record/60832/files/texto_completo.pdf$$yVersión publicada 000060832 8564_ $$s125902$$uhttps://zaguan.unizar.es/record/60832/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000060832 909CO $$ooai:zaguan.unizar.es:60832$$particulos$$pdriver 000060832 951__ $$a2017-11-28-10:31:15 000060832 980__ $$aARTICLE
