Our science and guiding principles are:

 

We study the physics of SOFT CONDENSED MATTER, i.e. materials which are easily deformable by external stresses, electric or magnetic fields, or by thermal fluctuations.

 

For this, we apply  ideas of COMPLEXITY, i.e. "To extract physical knowledge from a complex system,

one must focus on the right level of description, so.....we don't try to model bulldozers with quarks!!" :

Goldenfeld and Kadanoff: Science Vol. 284 p. 87, 2 April 1999.

Complexity means "reduction and removal of redundancy", as first defined by by the philospher John Locke (1632-1704):

"Ideas thus made up of several simple ones put together, I call complex; such as beauty, gratitude, a man, an army,

the universe.", and as illustrated in art by Picasso in his famous bull drawing. from 1945.

 

However, we are not doing philosophy, or art, we are doing real experiments in nanophysics and materials science:

In order to understand better the relation between Complexity and Materials Science, we suggest reading Chapter 2 named:

"How do Complex Phenomena Emerge from Simple Ingredients", in this

Report from the National Academies of Sciences: Committee on Condensed Matter and Materials Physics 2010,

(CCMP 2010).

 

This means: Complex is NOT the same as complicated!

 

Our main physical model system is: Nano-layered silicates, or in other words CLAYS, which are soft because they are

built from complex self-assembled structures of nanoparticles.

We can recommend this recent book: "Handbook of Clay Science 1" edited by F. Bergaya, B.K.G. Theng and G. Lagaly,

ELSEVIER May 2006, where the following statement can be found:

"As clays and clay materials are abundant, inexpensive and environmentally friendly,

they will most likely be known as the materials of the 21st century."

Other materials that we study and use as model systems for soft and complex materials are

paper, zeolites, surfactants, polymers etc.

 

We thus wish to focus on, and study thoroughly a few physical systems, such as clays, representative for soft and

complex matter, for a long time, from different points of view, using different experimental techniques,

thus studying interconnected complex physical phenomena.

 

Our main motivations are:

  • Developing new understanding of the basic physical properties and processes in soft and complex matter from
    the nano scale to the.human and geological scale.

  • Work on universal problems of practical relevance to fields of actual importance to society,
    ranging from nanotechnology to environmental topics.

Our scientific keywords are:

 

  • Soft condensed matter physics

  • Nano-physics

  • Complex matter

  • Complex processes

  • Pattern formation

  • Complexity

  • Anomalous diffusion

  • Spontaneous self-assembly

  • Guided self-assembly
