When a Bose–Einstein condensate is set to rotate, superfluid vortices will be formed, which finally condense into a vortex lattice as the rotation frequency further increases. We show that the dipole-dipole interactions renormalize the short-range

Within the t-J model, the heat transport of electron-doped cobaltates is studied based on the fermion-spin theory. It is shown that the temperature dependent thermal conductivity is characterized by the low temperature peak located at a finite temper

Within the charge-spin separation fermion-spin theory, we show that the mechanism of superconductivity in the electron doped cobaltate NaxCoO2·yH2O is ascribed to its kinetic energy. The dressed fermions interact occurring directly through the kinet

The ground powders with the same particle size distribution and the same mean particle diameter were prepared by five different types of mills. The flowability index (FI) and the particle shape indices, namely, Wadell's working sphericity Φw and cir

The c-axis charge transport of the hole doped triangular antiferromagnet is investigated within the t-J model by considering the incoherent interlayer hopping. It is shown that the c-axis charge transport of the hole doped triangular antiferromagnet

The effect of the extra second neighbor hopping t' on the incommensurate spin correlation in the t-J model in the underdoped regime is studied within the fermion-spin theory. It is shown that although the extra second neighbor hopping t' is systemati

The doping dependence of magnetic fluctuations in the underdoped copper oxide materials are studied within the t-J model. It is shown that away from the half-filling, the magnetic Bragg peaks from the dynamical spin structure factor spectrum S(k,omeg
