Electronic transport properties of quasicrystals: a Review
... We also note that the curves σ(T ) are nearly parallel. This point suggests to write σ(T ) = σ4K + δσ(T ) with σ4K a measure of conductivity at 4 Kelvin and δσ(T ) the variation as a function of temperature which is nearly independent of the alloy (fig. figicopar). This is a general behavior of all ...

Chapter 1. Some experimental facts
... A spherical shell of width dk has a volume 4 π k2 dk . But only one eighth correspond to physical solutions since other parts correspond to negative values of one or more of the components kx , ky or ,kz . Hence the number of states having a wave number between k and k+dk is obtained dividing 4 π k2 ...

If this force is always directed toward the equilibrium position, repetitive backand-forth motion occurs about this position. Such motion is called perio ...
