Tom Kirkwood

Tom Kirkwood is Professor of Medicine and Director of the Institute for Ageing and Health at Newcastle University, UK. After training in mathematics and biology at the Universities of Cambridge and Oxford he first worked on the measurement of blood clotting and fibrinolytic factors. Early in his career he began an interest in the biology of ageing which he has followed since 1975. In 1977 he pu...

Resonant tunneling of electromagnetic waves through polariton gaps

We consider resonant tunneling of electromagnetic waves through an optical barrier formed by dielectric layers with the frequency dispersion of their dielectric permiability. The frequency region between lower and upper polariton branches in these materials presents a stop band for electromagnetic waves. We show that resonance tunneling through this kind of barriers is qualitatevely different f...

Existence of Spectral Gaps, Covering Manifolds and Residually Finite Groups

In the present paper we consider Riemannian coverings (X, g) → (M, g) with residually finite covering group Γ and compact base space (M, g). In particular, we give two general procedures resulting in a family of deformed coverings (X, gε) → (M, gε) such that the spectrum of the Laplacian ∆(Xε,gε) has at least a prescribed finite number of spectral gaps provided ε is small enough. If Γ has a pos...

Kirkwood correlation factors in liquid mixtures from an extended Onsager-Kirkwood-Fröhlich equation.

Two approaches for applying the Onsager-Kirkwood-Fröhlich equation to liquid mixtures are revisited at the light of recent developments leading to the estimation of relative permittivities and refractive indices of thermodynamically ideal liquid mixtures. From the one-liquid approach, the squared permanent dipole moment of the mixture molecular-equivalent species M is demonstrated to be a mole-...
