A METHOD OF APPROXIMATE SECOND QUANTIZATION IN THE THEORY OF SUPERCONDUCTIVITY
Technical Report

OSTI ID:4217997
The Hamiltonian of a dynamic system of Fermiparticles is transformed by means of the general unitary transformation proposed by N. N. Bogolubov. From this Hamiltonian is obtained the approximate second quanitization (a.s.q.) Hamiltonian introducing the Boseamplitudes with two indices. This Hamiltonian is diagonalized and the collective oscillations considered, especially for the pairs of particles with parallel spins. For the forced collective oscillations the paramagnetic term in the Hamiltonian is also taken into account. This term leads to the additional "spin" current, connected with the elementary excitations with spin-moment plus or minus 1. If the transfer momentum tends to zero, this current vanishes as the terms omitted in obtaining the Meissner-Ochsenfeld effect. (auth)
