Polymers continue to attract considerable interest. As part of probability theory, combinatorics and statistical physics, polymer models are designed to describe and help understand the configurational and thermodynamic properties of polymer molecules in a variety of different situations.
Linear polymer molecules are characterised by spatial flexibility and by
self-interaction and interaction with their surroundings.
Models are needed which take account of their resulting configurational degrees of freedom. The simplest models are random walks and directed walks. Self-avoiding walk models are more difficult, but they properly account for the excluded-volume effect, i.e. the fact that monomers take up space to the exclusion of other monomers.
Polymers can exhibit phase transitions. For instance, a polymer can change
from an expanded coil to a compact ball when the temperature is decreased, due
to self-attraction or repulsion from a liquid in which it is immersed. Similarly,
polymers can adsorb at a surface, with a phase transition from adsorbed to
desorbed behaviour as the temperature is increased. There are additional
complications in random copolymers, where the polymer consists of at least two
types of monomers, arranged along the polymer chain in a random order. Random
copolymers exhibit collapse and adsorption transitions, and there are
challenging questions about how the randomness affects the nature of the phase
Random copolymers can also localize at an interface between two immiscible liquids, distributing their monomers between the two liquid phases to optimise their energy.
This workshop is designed to review recent progress in the study of polymers. The emphasis will be on their rigorous mathematical treatment. The workshop is intended to bring together researchers in probability theory, combinatorics and statistical physics.
