Abstract

Since 1955 Progress in Low Temperature Physics has continued to monitor scientific achievements in the realm of low-temperature physics. Obtaining low temperatures used to be an aim in itself in the past, whereas nowadays achieving millikelvin temperatures is a routine experimental procedure. However, the properties of materials at these low temperatures contine to produce fascinating physics: the liquid, solid and superfluid, phases of the quantum fluids ³He and ⁴He as well as 'new' materials such as high-temperature superconductors and tiny quantum devices display their macroscopic quantum behavior only at the lowest temperatures.

Volume XIII of this series continues the tradition of collecting fundamental studies of macroscopic quantum phenomena. In this volume, properties of new systems such as small circuits at low temperatures and high-Tc superconductors are studied. But the systems that are formed by ³He and ⁴He and their mixtures at low temperatures continue to dazzle and amaze with their ever more intricate properties studied with increasing accuracy. This volume provides the reader with an archival overview of the magic world of low temperatures as perceived by todays most sensitive probes.
