Hubbard modelground statestability of ferromagnetic statemagnetic polaronsThe estimations of the stability region of the lattice ferromagnetic ground state in the space of model parameters are found. For the triangular lattice strip formed by L segments with the total number of electrons N=L+1 we ...
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 anticommutative Green's functions and the energy spectrum of fullerene C60 have been calculated using the Hubbard model in the mean-field approximation. Based on the obtained energy spectrum, the interpretation of the experimentally observed bands of optical absorption has been proposed and the...
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 (...
Interaction terms were retained in the model if they appeared significant by the Wald statistical test; a 2-sided P < .05 indicated statistical significance. From these separate analyses, we excluded small subgroups of participants with ε2ε2 (44 with normal cognition, 2 with subjective ...
one picture9concerning the inter-orbital Hubbard interaction between different orbitals and orbital selective pairing is proposed, which expects not only ad-wave gap on the α pocket, but also full gaps on the β and γ ones with opposite gap signs. The latter is a bit like the s±pairing ...
