Unconventional superconductivity

Tomonaga-Luttinger liquid state [14-16], unconventional superconductivity [17], etc. These molecular conductors once used to be called organic metals, but nowadays this terminology has become obsolete in order to avoid possible confusion with organometallies. ...

This volume contains the proceedings of the 2004 University of Miami Workshop on Unconventional Superconductivity. The workshop was the fourth in a series of successful meetings on High-Tc Superconductivity and related topics, which took place at the James L. Knight Physics Building on the University of Miami campus in Coral Gables, Florida, in January 1991, 1995, 1999, and 2004. 

Fig. 12. Schematic phase diagram for CevCii2Si2. 7V is the Rondo temperature. TN and T( are the magnetic and SC transition temperatures, respectively. Tm is the temperature below which / T starts to decrease (/ NMR signal intensity). 7> is the temperature below which the T T = constant relation holds. The region denoted by slanting lines is the critical region where the static magnetic order crossover to the unconventional superconductivity occurs.

Especially for the strongly anisotropic materials, there are however experiments which seem to indicate unconventional superconductivity. As coupling mechanisms for the Cooper pairs, non-phononic interactions, e.g. magnetic correlations, have been discussed. It is also not completely certain whether the pair wavefunc-tions have s-state symmetry or instead have p- or d-w2cve symmetry. There are many parallels to the inorganic high-temperature superconductors. 

Important contributions have also been made by (tSR in elucidating the superconducting properties of HF materials. This aspect is not covered in this review. We just point out that the weak magnetic state may be a fundamental ingredient for unconventional superconductivity, one of the most exciting aspects of HF behavior. 

In this field the search for unconventional superconductivity has become a major focus...
