Conference Announcement:
Local and Nanoscale Structure in Complex Systems
16-21 September, Hotel Loretto, Santa Fe, New Mexico

Sponsored by:
Los Alamos National Laboratory, the Stanford Synchrotron Radiation
Laboratory, and the Laboratory for Research on the Structure of
Matter at the University of Pennsylvania
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? (Chaired by Alan Bishop, LANL)
Origins and Organization of Local and Extended Lattice Distortions
Spatial and Temporal Probes, Theory and Experiment (Chaired by
Dragan Mihailovic, Josef Stefan
Institut)
Multiple Minima in (Free) Energy Landscapes (Chaired by Hans
Frauenfelder, LANL)
Multiscale Organization and Functionality: Consequences for
Macroscopic Properties and Phase
Stability (Chaired by James Phillips, Bell Labs)
Technological Implications and Structural Control
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. 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.
