Abstract: The microscopic theory of the low temperature superconductivity is reviewed along with the mechanism of electron-electron interaction. We have investigated the electri- cal and magnetic properties of superconductors. Our current research, which is fully theoretical and analytical, is targeted in illustrating and explaining the quasiparti- cles 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 elemen- tary excitations. We have shown that as the quasiparticles (electron like and hole like) have a fractional charge, depending on their energy.
