3d Focus Week (September 17-21, 2001)

QUANTUM DISCRETE BREATHERS

Coordinator : Victor Fleurov

Recent years witnessed a lot of activity in the field of discrete breathers, spatially localized solutions in classical lattices (or maps) with nonlinear (anharmonic) interactions. The third Focus Week will be devoted to the discussion of quantum properties of discrete breathers. The Focus Week will bring together experts from various field varying from mathematics to physics and chemical physics, including both theorists and experimentalists with the aim to give a boost to the field of quantum breathers.

Contributions to and discussions on the following topics and related subjects are invited:

  • General aspects of quantization of discrete breathers
  • Quantum breathers in various models, NLS, Hubbard model, spin systems and others
  • Experimental observations
  • Dynamics of highly excited vibrational states of molecules, doorway states

    The focus week will have an informal character with the program offering plenty of time for discussions to exchange ideas and methods, to stimulate cooperations and to do theoretical work right ``on the spot'' using the excellent facilities of the Max Planck Institute. The links of the Focus Week with the other parts of the event including the workshop will give us the possibility to interact with colleagues working in other subfields of nonlinear science with mutual benefit.
