Non-local correlation effects in the half-filled Hubbard model on an isotropic triangular lattice are studied within a spin polarized extension of the dual fermion approach. A competition between the antiferromagnetic non-collinear and the spin liquid states is strongly enhanced by an incorporation of...
The energy spectra of single-wall carbon nanotubes (CNTs) with chiralities of (10, 10), (11, 9), and (12, 8) are calculated in the static fluctuation approximation for the Hubbard model. The choice of these systems for investigation was dictated by the fact that these systems are the ...
A microscopic theory for the electron spectrum of the CuO 2 plane within an effective p-d Hubbard model is proposed. The Dyson equation for the single-el... NM Plakida,VS Oudovenko - 《Journal of Experimental & Theoretical Physics》 被引量: 77发表: 2007年 The Influence of Magnetic Imperfe...
Here we focus on the nearly ideal honeycomb lattice material YbCl3 as a potential model quantum magnet in the unfustrated limit. The arrangement of the Yb3+ ions is illustrated in Fig. 1. While YbCl3 is formally monoclinic (space group C12/m1), there is only a very modest distortion (...
Energy spectrum of a model of narrow-band metal into which the periodically spaced Anderson-Hubbard centers are introduced has been studied. Hybridization with conduction band results in the indirect exchange interaction which is different from the interactions between localized magnetic moments and strong...

The energy spectrum and the optical absorption spectra of single-wall carbon nanotubes with chiralities (5,5), (10,0), (9,0), (12,0), and (15,0) is calculated within the framework of the Shubin–Wonsowskii–Hubbard model taking into account distant (adjacent to the nearest) interstitia...
