Flux Pumping for High-Tc Superconducting (HTS) Magnets
High Tc superconductors are enabling in the generation of extremely high magnetic fields. Flux pumping is a promising technology which can be used to operate HTS magnets without significant loss. In this decade, several HTS flux pumps based on travelling magnetic waves have been developed, yet …

Aspects of spin-charge separation in high Tc cuprates
High Tc, cuprates have a number of features that are anomalous from the point of view of the conventional theory of metals, i.e. the Fermi liquid theory. These include the high Tc itself, the linear resistivity in optimally doped cuprates, the "spin gap" phenomena, and antiferromagnetic …
