Structural and electronic properties of N-doped TiO2 anatase nanoparticles and their effects on the adsorption of Hydrazine (N2H4) molecule: A first-principles study

We have performed a density functional theory investigation on the structural and electronic properties of pristine and Nitrogen-doped TiO2 anatase nanoparticles as the adsorbents for removal and degradation of hydrazine molecules in the environment. We have presented the most stable adsorption configurations and examined the interaction of hydrazine molecule with these doped and undoped nanopa...

Coupled cluster treatment of an interpolating triangle-kagomé antiferromagnet

The coupled cluster method ~CCM! is applied to a spin-half model at zero temperature which interpolates between a triangular lattice antiferromagnet ~TAF! and a kagomé lattice antiferromagnet ~KAF!. The strength of the bonds which connect kagomé lattice sites is J, and the strength of the bonds which link the non-kagomé lattice sites to the kagomé lattice sites on an underlying triangular latti...

Indications of incommensurate spin fluctuations in doped triangular antiferromagnets

The incommensurate spin fluctuation of the doped triangular antiferromagnet is studied within the t-J model. It is shown that the commensurate peak near the half-filling is split into six incommensurate peaks in the underdoped and optimally doped regimes. The incommensurability increases with the hole concentration at lower dopings, and saturates at higher dopings. Although the incommensurabili...
