Meeting Description

This Gordon Conference will honor the memory of Professor Pierre-Gilles de Gennes, 1991 Nobel price in Physics, whose invaluable contribution to the field of superconductivity as to many other fields has guided many of us.

The 2007 Gordon Research Conference will be an interdisciplinary forum for exchange on the latest experimental results and theoretical advances in Superconductivity. The program will be designed in order i) to bring together world recognized experts whose diverse expertise should stimulate discussions and push cutting edge (interdisciplinary) research and collaborations. ii) explore some of the big challenges and convergences raised by "unconventional" superconductors. The selected specific topics are those whose emergence and rapid development are thought to be most relevant in making definite progress and open new directions. Moreover, the organizers will make every effort so that all important issues will be addressed clearly during the unhampered discussions which are the hallmark of Gordon Conferences.

Year 2007 provides a special opportunity for this GRC: the scientific community celebrates the 50th anniversary of the Bardeen-Cooper-Schrieffer (BCS) sweeping theory of superconductivity (1957-2007). Superconductivity transcends the limits of traditional condensed matter physics. In fields where BCS theory is relevant (e.g. cold atoms, quark matter), a vivid activity is expanding. Participants will be given the opportunity of hearing about some of the latest developments in these fields.

BCS theory is also presently challenged by the ongoing discovery of new superconductors. This Gordon Conference will cover important topics dealing with this challenge.

High critical temperature superconductivity in cuprates raises the crucial point of the role of doping in addressing any mechanism. Whether lightly doped cuprates are inherently different from heavily doped, cuprates -presumably more conventional- requires scrutinizing the phase diagram and the nature of the pseudogap phase. The interplay between superconductivity, magnetism, quantum criticality - most effectively studied in heavy fermions, and in rapid evolution in this field - may be central in both theoretical and experimental approaches. All these phenomena may be thought of as pertaining to the concept of emergence of new states of matter out of complex interactions.

The search for new materials is a hallmark of the field. Superconductivity at the nanoscale (e.g. carbon nanotubes or nanodevices) will also be addressed, as a possible key for new developments.

We will strongly encourage speakers to emphasize the presentation of new, unpublished work. We will ensure that discussions enlighten the outcome and the unsolved questions, and explore new directions. We strongly encourage students at the PhD and Post-doc level to present their ongoing work in the poster sessions. We also strongly encourage those from groups underrepresented in science to apply (some funding has been earmarked for members of these groups).
