New Frontiers in Casimir Force Control

Here is a link to the Satellite meeting, New Frontiers in Casimir Force Control, in Santa Fe, which was held immediately following QFEXT09, September 27-29, 2009.

Pictures are now available from the QFEXT banquet.

Here is a link to order pictures. Photographs can be ordered until November 21. Sometimes this link takes you to a page that asks for a PIN. In the box that asks for event name type QFEXT, and that should take you to the pictures!

Here is the final schedule of talks.

Topics of QFEXT09 included the following:

  • Casimir and van der Waals forces
    • Progress in theory and new experiments
    • Applications at micro- and nanoscale
  • Casimir effect
    • Exact and approximate methods
    • Related mathematical problems
  • Quantum vacuum effects in classical background fields
    • Renormalization
    • Singular backgrounds
    • Applications to particle, high energy, and atomic physics
  • Vacuum energy and gravity
    • Renormalization of Einstein's equations with singular source functions
    • Vacuum energy in supersymmetric and noncommutative theories

QFEXT09 was a continuation of a series of workshops of the same title held at the University of Leipzig in 1989, 1992, 1995, 1998, 2001, 2007, at the University of Oklahoma in 2003, and at the University of Barcelona in 2005. The average number of participants has been about 80. Started with the intention of bringing about an East-West scientific dialog, QFEXT developed into one of the most prominent meetings in the field of the Casimir effect, vacuum energy, and related questions in several areas, ranging from quantum field theory and cosmology to atomic, subnuclear, and experimental physics. Typically mathematical questions related to spectral geometry are represented as well.  These meetings have created a unique atmosphere where theoreticians, mathematicians and experimentalists are brought together for a week, where talks by colleagues that they might rarely hear otherwise often spark lively debate and result in numerous collaborations.

The Proceedings of the last six workshops were published as follows:

  • M. Bordag and V. M. Mostepanenko, eds., J. Phys. A 41, No. 16 (2008), special issue devoted to papers presented in the 8th workshop on Quantum Field Theory Under the Influence of External Conditions,
  • E. Elizalde and S. D. Odintsov, eds., J. Phys. A 39, No.21 (2006), special issue devoted to papers presented in the 7th workshop on Quantum Field Theory Under the Influence of External Conditions,
  • K. A. Milton, ed., Proceedings of the 6th Workshop on Quantum Field Theory Under the Influence of External Conditions (Rinton Press, Princeton, 2004),
  • M. Bordag, ed., Int. J. Mod. Phys. 17, Nos. 5&6, pp. 771-1064 (2002),

  • M. Bordag, ed., Quantum Field Theory Under the Influence of External Conditions (Teubner, Stuttgart, 1996).
  • Talks:
    The formal structure of the conference consisted of plenary and contributed talks, the latter organized in parallel sessions. In addition there was a poster session.
