College Pk: Amer Physical Soc, v. 76, n. 1, 6 p., 2007.1098-0121http://hdl.handle.net/11449/34138We investigate, through the density-matrix renormalization group and the Lanczos technique, the possibility of a two-leg Kondo ladder presenting an incommensurate orbital order. Our results indicate staggered short-range orbital order at half-filling. Away from half-filling our data are consistent with incommensurate quasi-long-range orbital order. We also observed that an interaction between the localized spins enhances the rung-rung current correlations.6engArtigo10.1103/PhysRevB.76.014422WOS:000248487900079Acesso restritoWOS000248487900079.pdf4459191234201599
