NONLINEAR ACOUSTIC PROPERTIES OF CONDUCTION ELECTRONS

These results were consis- tent with the existence on the low temperature state Fermi surface (T < Tp2 of small electron and hole pockets with a size of the order of lo~~ the

2.3. Trie thermoelectric power or Seebeck coefficient of trie hole doped cuprates varies strongly with doping and is usually positive. Typical behaviour for underdoped, optimally

We address the problem of uniform asymptotic approximations of the ground state η ε of the stationary Gross–Pitaevskii equation (1.2) using the Hasting–McLeod solution of

be obtained by stating that, at the critical energy E * *, the average tunnelling depth around the allowed regions is of the same order of magnitude as the

Under the conditions of preset current the por- tion of NDC is obtained on the stationary CVC (fi- gure 2)/2/. This is the first observation of NDC in the object which is not

This surprising result has been explained by Engelsberg and Simpson /3/ who showed that the in- fluence of the electron-phonon interaction on the dHvA effect is rather subtle
