Virtual graviton exchanges at the Z-pole in large extra dimensions [PDF]

open access: yes, 2002
In the framework of quantum gravity propagating in large extra dimensions, the effects of virtual Kaluza-Klein gravitons on the imaginary part of the amplitude of the process e+ e- --> f f-bar are analyzed at the Z-pole.

Virtual phonon exchange in glasses

open access: yesJournal de Physique, 1975
In this article we demonstrate the importance of the indirect interaction via the phonon field between pairs of defects in an amorphous material. Using only the approximate value of the lattice coupling constant it is shown that the exchange interaction is large. The most important conclusion that can be drawn from this calculation is that the order of

A random tunnel number one 3-manifold does not fiber over the circle [PDF]

open access: yes, 2006
We address the question: how common is it for a 3-manifold to fiber over the circle? One motivation for considering this is to give insight into the fairly inscrutable Virtual Fibration Conjecture.
