Progress in Low Temperature Physics: v. 9

"Progress in Low Temperature Physics" has been progressing since 1955 to monitor scientific achievements in the realm of low-temperature physics. In the older days, obtaining low temperatures was an aim in itself, whereas nowadays achieving millikelvin temperatures is a routine experimental procedure. However, the properties of materials at these lowest temperatures continue to produce fascinating physics: the liquid, solid and superfluid phases of the quantum fluids 3 He and 4 as well as "new" materials such as high-temperature superconductors and tiny quantum devices display their macroscopic quantum behavior at the lowest temperatures.
