Registration Deadline:  August 31, 2001

Los Alamos National Laboratory, the Stanford Synchrotron Radiation
Laboratory, and the Laboratory for Research on the Structure of Matter at
the University of Pennsylvania

Scope and Topics
The scientific motivation for this meeting goes back ten years to the
controversial observation of local lattice distortions in cuprates, which
inspired the Local Lattice Effects in High Temperature Superconductors
conference that was also held in Santa Fe in 1992.  Since then it has been
recognized that these displacements were a manifestation of the "stripes"
that occur in correlated metal oxides.  It is also becoming clear, however,
that such behavior is far from unique.  The spontaneous development of
nanoscale organization coupled to functionality is apparently common to
many types and classes of materials, especially complex ones that exhibit
correlated electron and atom behaviors that are manifested as phase
instabilities and unusual chemical reactivity.  These unusual
characteristics may therefore originate in the interactions between the
resulting differently ordered domains and the attributes of the domain
walls instead of bulk characteristics that assume a periodic lattice.  The
special properties that ensue have generated much of the current interest
in nanoscience.  Since nanoscale structure has always been recognized as
intrinsic to soft matter and biomolecules, many of the ideas and methods
already used in, e.g., biological physics, could be extended to condensed
matter, and vice versa.

It is therefore timely to explore the origins of multiple stable
conformations of atoms, their collective interactions that promote
nanoscale organization, how they influence or even determine functionality,
and the possibility of controlling structure and properties at this level
in all of these classes of materials.  To foster a truly interdisciplinary
meeting the conference sessions will be devoted to common nanoscience
issues instead of the different substantive areas:

® Observations of Nanoscale Structure and Organization: A fundamental
   characteristic of complex systems?
   Alan Bishop, LANL, cochaired by Jose Mustre de Leon, CINVESTAV Merida
® Origins and Organization of Local and Extended Lattice Distortions
   James Phillips, Bell Labs, cochaired by Despina Louca, University of
Virginia
® Spatial and Temporal Probes, Theory and Experiment
   Dragan Mihailovic, Josef Stefan Institute, cochaired by Richard Lesar, LANL
®Multiple Minima in (Free) Energy Landscapes
   Hans Frauenfelder, LANL, cochaired by Dale Sayers, North Carolina State
University
®Multiscale Organization and Functionality: Consequences for Macroscopic
   Properties and Phase Stability
    Dick Siegel, Rennselaer Polytechnic Institute, cochaired by Art
Ramirez, LANL
® Technological Implications and Structural and Synthetic Control
   Martha Krebs, California Nanoscience Institute UCLA, cochaired by Robin
Farrow,
   IBM Almaden Research Center

Conference Format
Speakers will be asked to address these topics via their recent work using
a more detailed description of the salient issues for each topic compiled
by the session chairs.  In addition to this introduction, each session will
end with a discussion period, and ample time will be available for the
participants to meet informally.  Another factor that we believe will
encourage success is that, as a "bottom up" rather than "top down"
conference, the motivation and emphasis will utilize a pragmatic approach
to "complexity" based on actual examples and work.  Relevant classes of
materials include correlated and transformational crystalline solids, mixed
valence oxides and alloys, catalysts, polymers and other soft or molecular
compounds, proteins, actinides and other f-electron systems,
semiconductors, photoexcited transformational compounds, and fabricated
heterostructures.

There will also be a special session honoring Jim Krumhansl's eighth decade.

The range of expertise of the chairs, speakers, and other registered
participants will foster debate towards the resolution of many specific
nanoscience and complex materials issues:
®Diffuse scattering analysis, PDF, and XAFS as means for total structure
determination.
®The coupling of local atomic and electronic structure.
®Energetics and dynamics of multi-conformational systems.
®Multiple nanoscale component engines as drivers functionality in complex
materials.
®Application of energy landscape approaches to crystalline materials.
®Finite temperature thermodynamics on multiple scales.
®Non (or local) -equilibrium synthetic approaches.
