Abstract
The microscopic theory of the low temperature superconductivity is reviewed along
with the mechanism of electron-electron interaction. We have investigated the electrical
and magnetic properties of superconductors. Our current research, which is fully
theoretical and analytical, is targeted in illustrating and explaining the quasiparticles
in the superconducting states of a metal. In this work, a comparatively simple
mathematical procedure is developed in finding the energy of the ground state of a
superconductor, the energy gap and dispersion relation of the energy of the elementary
excitations. We have shown that as the quasiparticles (electron like and hole
like) have a fractional charge, depending on their energy
