Sistemas antiferromagneticos unidimensionais de spin-1
(Universidade Federal de Minas GeraisUFMG, 2007-08-31)
Attending to the current tendency of research in quantum magnetism,our object of study comprises one-dimensional spin-1 antiferromagnetic(AFM) systems. They are analysed for two different physical pictures: anoise-driven ...

Construção de líquidos de spin quirais por junções de cadeias de spin
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA, 2021-03-26)
In this thesis work, it was sought to present a new theoretical construction method
of a chiral spin quantum liquid formed from Heisenberg spin chains. The spin chains,
initially assembled in trios, were coupled in the ...
