A field-oriented chain of dipolar particles in elongational flow
We study the behavior of an isolated field-oriented chain of dipolar particles in elongational fluid flow. Our main goal is

Are the calorimetric and elastic Debye temperatures of glasses really different?
Below 1 K, the specific heat Cp of glasses depends approximately linearly on temperature T, in contrast with the cubic

A Rotating-Valence-Bond scenario for the 2D Antiferromagnetic Heisenberg Model
We propose that the valence bonds forming the ground state of the 2D-AF Heisenberg model on a square lattice may

A texture tensor to quantify deformations
Under mechanical deformation, most materials exhibit both elastic and fluid (or plastic) responses. No existing formalism derived from microscopic principles

A texture tensor to quantify deformations: the example of two-dimensional flowing foams
In a continuum description of materials, the stress tensor field $\bar{% \barσ}$ quantifies the internal forces the neighbouring regions exert

Black holes, the Wheeler-DeWitt equation and the semi-classical approximation
The definition of matter states on spacelike hypersurfaces of a 1+1 dimensional black hole spacetime is considered. Because of small

Can we build a sensible theory with broken charge and colour symmetries?
Charge and colour symmetries are broken using the vevs of scalar fields, but it is shown the theory possesses a

Conservation laws for the voter model in complex networks
We consider the voter model dynamics in random networks with an arbitrary distribution of the degree of the nodes. We

Do LEP results suggest that quarks have integer electric charges?
We argue that recent results from two-photon processes at LEP are better explained by quarks possessing integer electric charges.
