FOREWORD
These Proceedings of a NATO-ARW (HTECH ARW 97 1843) held at the Oreanda
Hotel, Yalta, Ukraine from April 29 till May 2 , 1998 resulted from many discussions
between various workers, concerning the need for a gathering of all (if possible) who
were concerned with the subject of symmetry of the order parameter and pairing states
for superconductivity. We applied ourselves in particular to High critical Temperature
Superconductors (HTS), but also studied other unconventional superconductors. The
study of HTS is one of the most prominent research subjects in solid state sciences.
The understanding of the role of symmetry and pairing conditions are also thought to
be necessary before technological applications since these features may be influenced
by external fields.
The workshop discussions have touched upon theoretical and experimental aspects, but
also on related topics. These served as initiators for a very great amount of discussions
with many comments from the audience. More than thirty "long lectures" and one on
going "poster session" were held. Private discussions went unrecorded but obviously
took place at many locations : lecture halls, staircases, cafes, bedrooms, bars,
beach,bus, plane... Arguments openly reported for the first time were often quite
sharp ones, -and this is an understatement.
The ARW was held starting from 09:00 every day; the morning session ending at
01:30 p.m.; lunch till 02:00 p.m.; free afternoon for discussion or short excursions
allowing for exchange of ideas; after each supper an evening session was held, one of
them lasting till 11: 30 p.m. Due to the need of a charter plane to be taken between
Kiev and SemfiropollY alta, almost all participants stayed (had to stay!) during the
wholeARW.
The Proceedings are more or less arbitrarily divided into three parts : one is reserved for
papers mainly considering theoretical aspects, thoilgh not neglecting experimental data.
