Adsorption at domain edges

Chromaticity of Turan Graphs with At Most Three Edges Deleted

Let $P(G,lambda)$ be the chromatic polynomial of a graph $G$. A graph $G$ ischromatically unique if for any graph $H$, $P(H, lambda) = P(G,lambda)$ implies $H$ is isomorphic to $G$. In this paper, we determine the chromaticity of all Tur'{a}n graphs with at most three edges deleted. As a by product, we found many families of chromatically unique graphs and chromatic equivalence classes of graph...

A ug 1 99 9 Critical adsorption near edges

Symmetry breaking surface fields give rise to nontrivial and long-ranged order parameter profiles for critical systems such as fluids, alloys or magnets confined to wedges. We discuss the properties of the corresponding universal scaling functions of the order parameter profile and the two-point correlation function and determine the critical exponents η and η ⊥ for the so-called normal transit...

Theory of topological edges and domain walls.

We investigate domain walls between topologically ordered phases in two spatial dimensions. We present a method which allows for the determination of the superselection sectors of excitations of such walls and which leads to a unified description of the kinematics of a wall and the two phases to either side of it. This incorporates a description of scattering processes at domain walls which can...

Keep nibbling at the edges.

Alifelong passion for natural history and an aptitude for chemistry had led me to study for a B.Sc. in biochemistry at University College London (UCL) from 1963 to 1966. It was during this period that the allosteric theory of enzyme regulation was put forward by JacquesMonod, Jean-Pierre Changeux, and Francois Jacob at the Institute Pasteur. This explained how the end products of a biosynthetic...
