The f-sum rule is applied to the conduction- and valence-band edges at the L point in PbS, PbSe, and PbTe. Experimental values of the energy gaps and electron and hole effective masses for PbS and PbSe follow the f-sum rule while those for PbTe do not. It is proposed that the well...
作者: J Kosztin 摘要: In the zero momentum transfer limit the conditions for finite electronic Raman intensity are presented. The right hand side of the generalized f-sum rule is calculated, where in the dynamical structure factor the electron density is replaced by an effective density describi...

Using a QCD estimate on the quark-vacuum condensate ratio (ss)0/(uu)0 the authors show, by deriving a sum rule, that the ratio of the meson wavefunction renormalization constants ZK12//Zpi 1/2 may deviate considerably from the SU(3) symm... S Basu,S Niyogi - 《Journal of Physics G...
It is shown that certain sum rule identities exist which relate correlationfunctions for $n$ Potts spins on the boundary of a planar lattice for $n\geq4$. Explicit expressions of the identities are obtained for $n=4,5$. It is alsoshown that the identities provide the missing link needed ...
