Representations of G+++ and the role of space-time
A. Kleinschmidt, P. West
We consider the decomposition of the adjoint and fundamental representations of very extended Kac-Moody algebras G+++ with respect to their regular A type subalgebra which, in the…
Penrose Limits and Spacetime Singularities
Matthias Blau, Monica Borunda, Martin O'Loughlin +1
We give a covariant characterisation of the Penrose plane wave limit: the plane wave profile matrix is the restriction of the null geodesic deviation matrix (curvature tenso…
Space-Time Foam may Violate the Principle of Equivalence
John Ellis, N. E. Mavromatos, D. V. Nanopoulos +1
The interactions of different particle species with the foamy space-time fluctuations expected in quantum gravity theories may not be universal, in which case different types of en…
Non-renormalization for planar Wess-Zumino model
Jean Alexandre
Using a non-perturbative functional method, where the quantum fluctuations are gradually set up,it is shown that the interaction of a N=1 Wess-Zumino model in 2+1 dimensions does n…
The spin-echo system reconsidered
D. A. Lavis
Simple models have played an important role in the discussion of foundational issues in statistical mechanics. Among them the spin--echo system is of particular interest since it c…
Reply to Comment on "Fluctuation-dissipation relations in the non-equilibrium critical dynamics of Ising models"
Peter Mayer, Ludovic Berthier, Juan P. Garrahan +1
We have recently shown that in non-equilibrium spin systems at criticality the limit $\Xin$ of the fluctuation-dissipation ratio X(t,tw) for t >> tw >> 1 can be measured using obse…
