Collective Aspects of Stochastic Non-Equilibrium Phenomena at Surfaces and Interfaces from 14 Jun 2004 through 25 Jun 2004
The purpose of the meeting is to bring
together experts in experiment, theory, and computer simulation, working on
collective stochastic phenomena in condensed matter physics, in particular in
surface and interface physics, to intensify interactions between these
communities and facilitate new joint projects.
Stochastic, non-equilibrium processes form a popular theme in modern research
in condensed matter and statistical physics. The two-dimensional playground
constituted by the surfaces and interfaces of condensed matter systems provides
a multitude of exciting and highly relevant experimental and practical
realizations of a variety of models considered in analytical theory and
computer simulations. Typical examples of the processes of interest for the proposed
workshop are surface diffusion, crystal growth or erosion, surface phase
transitions, chemical reaction front dynamics, contact dynamics and friction.
Where the experimental focus in this area has long been on the atomic-scale
detail of these processes, the more sophisticated experimental tools and
improved analysis techniques available today are enabling new types of
investigations, covering the full hierarchy of length scales from that of a
single atom to that of the resulting collective response of the two-dimensional
system. A similar development can be observed in ab initio theory (e.g. DFT)
and computer simulations, which nowadays can handle sufficiently large systems
over sufficiently long time scales, by virtue of the available computer power
and of newly developed, smart computational strategies, that they both
incorporate the essential microscopic aspects and capture the emerging
collective behavior on larger length and time scales. At the statistical
mechanics side, progress in the fundamental understanding of collective
phenomena in non-equilibrium statistical processes has been rapid, due to the
application of scaling theory, generalized from its roots in equilibrium phase
transitions during the last quarter of the 20th century, numerical simulations,
and exact solutions (e.g., the Bethe Ansatz method in specific one-plus-one
dimensional processes, like KPZ growth and asymmetric exclusion transport
In addition to being scientifically highly challenging, the new approaches in experiment,
theory, and computer simulations embody the essential ingredients of the
translation of basic, atomic- and molecular-scale phenomena to the mesoscopic
and macroscopic regime of the response of a complete system to non-equilibrium
conditions, which will become important for a wide variety of smart, future
Specific examples of links that will be explored are:
§Experiments on friction and
models of driven diffusive flow.
§Experiments on catalytic
surface reactions and models of absorbing state dynamic phase transitions.
§Crystal growth in the
presence of additional degrees of freedom, such as surface reconstruction and
This is an open workshop, limited only by the
capacity of the facilities, a maximum of 60 participants.
The number of invited participants, of the order of 21-24, will be chosen
equally between experimentalists, theorists, and computer simulation experts.
Each invitee will present an overview-type talk about their specialty.
We invite all our coleagues, in particular those in the Netherlands, to attend
our workshop. We specifically encourage junior scientists (graduate students
and postdocs) to attend.
