Q: It was discovered that the ground state of a material is unstable with respect to these groups in 1956. Quite resistant to vibrations within the lattice, they move about relatively unaffected by thermal vibrations below the critical temperature. Since it takes a non-zero amount of energy to break them, and imperfections in superconducting solids, which would normally lead to resistance, are incapable of breaking them, no dissipation and no resistance exist. FTP, name these units formed by superconducting or superfluid state electrons in which two electrons act as a single unit.
