Scope of the seminar
Pattern formation is ubiquitous in nature and materials. The detailed processes that lead to patterns in physical, chemical, or biological systems as well as in material science may differ greatly. But on the macroscopic level, they often share generic properties, which can be described in the case of homogeneous systems by universal continuum models.
Naturally driven pattern forming systems, however, are often exposed to symmetry breaking mechanisms, e. g. to spatial variations of (material-) parameters and external fields or to varying geometrical constraints, which may affect patterns and their dynamics. Controlled applications of symmetry breaking fields provide often additional insights into pattern forming processes or they lead to new fascinating spatio-temporal phenomena ('creation'). Moreover, broken symmetries can even trigger pattern formation, as for instance morphogen gradients in developmental biology or inhomogeneities in microfluidics. Share different inhomogeneous pattern forming systems also common generic phenomena?
Active matter is a class of systems far from thermal equilibrium, which have the propensity for pattern formation, too. Examples of this class are the (individual or collective) behavior of swimmers, deformable particles in flow, vibrated grain experiments, cilia and flagella (beating individually, magnetically actuated or synchronized), pattern formation in active (filament) suspensions, etc. Phenomena in active matter provide also food for thought to experimentalists and theorists wishing to understand the random motion of individual active particles or a modest number of these as well as the emergence of collective behavior and pattern formation.
The 548th Wilhelm and Else Heraeus Seminar will provide an excellent opportunity and starting point to create, to discuss, and to test effective non-equilibrium descriptions of active matter starting from the particle level up to continuum models as well as generic descriptions of inhomogeneous pattern forming systems.

The 8th Lorenz Kramer Memorial Lecture will be delivered by Gerhard Ertl (Fritz-Haber-Institute in Berlin, Germany; Physicist, Nobel Prize in Chemistry 2007) on Tuesday, October 8, in the afternoon (former lectures). The Department of Physics at the University of Bayreuth recognizes in this way the outstanding contributions of the late Professor Lorenz Kramer to the focus subject "Nonlinear Physics" at Bayreuth. The support of the Emil-Warburg foundation, which has received particular donations for this purpose, is gratefully acknowledged.
In the evening of Tuesday, we will have a dinner at a restaurant in the center of Bayreuth.
The seminar will end on Wednesday, October 9, at noon.
The meeting is supported by the Wilhelm und Else Heraeus-Stiftung.
Applications should be sent immediately with the title and an abstract of the contribution to our e-mail address
Please use this template file: abstract2013.doc. The deadline for applications will be Friday, September 6, 2013.
On Monday, October 7, we will have a short oral poster presentation in the afternoon.
On this occasion, every participant presenting a poster is asked to introduce her/his poster within 3 minutes or less. You can either use a transparency for the overhead projector or prepare a PDF-file or PPT-file (max. 2 slides, no video files please) for the video projector. In the latter case, you must send your file to the conference office firstname.lastname@example.org before Thursday, October 3, 2013.
