WebElectron correlations are strong when the on-site electron—electron repulsions U are much larger than the energies associated with the hybridization of atomic orbitals belonging to different atoms. The latter are characterized in a solid by the width W of the energy band under consideration. A large ratio U/W is expected in systems involving 4f or 5f electrons, … WebNov 8, 2013 · Compatibility with quantum Monte Carlo allows for variational energy evaluations and an antisymmetric geminal power reference, two features not present in traditional coupled cluster that facilitate a nearly exact description of the strong electron correlations in minimal-basis N 2 bond breaking.

WebWe report the first study of electrical resistivity, magnetization, and specific heat on YbCo2. The measurements on a single-phased sample of YbCo2 bring no evidence of magnetic ordering down to 0.3 K in a zero magnetic field. The manifestations of low Kondo temperature are observed. The specific heat value divided by temperature, C/T, keeps … city of lee\u0027s summit portal
