Electrons, to chapter 4 for a discussion of the related topic of superconductivity. Before focusing specifically on low-temperature aspects we shall review some of the basic concepts of electronic behaviour in solids. As in the description of phenomena arising from lattice vibrations, the states lying immedia

Unlike .He, however, the .He atom (2 protons, 1 neutron, 2 electrons) is composed of an uneven number of fundamental particles. It therefore possesses a resultant spin, of .The .He atom is thus a

There are, of course, many processes and devices which can only be operated at temperatures below 100 K, simply because the physical phenomenon’ on which they are based, e.g. superconductivity or superfluidity,
