Non-holonomic Quantum Devices
V. M. Akulin, V. Gershkovich, G. Harel
We analyze the possibility and efficiency of non-holonomic control over quantum devices with exponentially large number of Hilbert space dimensions. We show that completely control…
A new population of WIMPs in the solar system and indirect detection rates
Lars Bergstrom, Thibault Damour, Joakim Edsjo +2
A new Solar System population of Weakly Interacting Massive Particle (WIMP) dark matter has been proposed to exist. We investigate the implications of this population on indirect s…
E_(10), BE_(10) and Arithmetical Chaos in Superstring Cosmology
Thibault Damour, Marc Henneaux
It is shown that the never ending oscillatory behaviour of the generic solution, near a cosmological singularity, of the massless bosonic sector of superstring theory can be descri…
Trieste lectures on solitons in noncommutative gauge theories
Nikita A. Nekrasov
We present a pedagogical introduction into noncommutative gauge theories, their stringy origin, and non-perturbative effects, including monopole and instanton solutions
Noncommutative Geometry Year 2000
Alain Connes
We describe basic concepts of noncommutative geometry and a general construction extending the familiar duality between ordinary spaces and commutative algebras to a duality betwee…
D-branes, Categories and N=1 Supersymmetry
Michael R. Douglas
We show that boundary conditions in topological open string theory on Calabi-Yau manifolds are objects in the derived category of coherent sheaves, as foreseen in the homological m…
Combinatorics of (perturbative) quantum field theory
Dirk Kreimer
We review the structures imposed on perturbative QFT by the fact that its Feynman diagrams provide Hopf and Lie algebras. We emphasize the role which the Hopf algebra plays in reno…
Noncommutative instantons revisited
Nikita A. Nekrasov
We find a new gauge in which U(1) noncommutative instantons are explicitly non-singular on the whole noncommutative R^4, thus resolving the previous confusions of the author. We st…
Numerical Black Hole Interiors and String Cosmology Initial Conditions
Richard Madden
Recent work has proposed the principle of `asymptotic past triviality' to characterize the initial state in the pre-big bang scenario of string cosmology, that it is a generic pert…
Perturbations of brane worlds
Nathalie Deruelle, Tomas Dolezel, Joseph Katz
We consider cosmological models where the universe, governed by Einstein's equations, is a piece of a five dimensional double-sided anti-de Sitter spacetime (that is, a "-symm…
Equivalence between the ADM-Hamiltonian and the harmonic-coordinates approaches to the third post-Newtonian dynamics of compact binaries
Thibault Damour, Piotr Jaranowski, Gerhard Schäfer
The third post-Newtonian approximation to the general relativistic dynamics of two point-mass systems has been recently derived by two independent groups, using different approache…
A Comparison of search templates for gravitational waves from binary inspiral
Thibault Damour, Bala R. Iyer, B. S. Sathyaprakash
We compare the performances of the templates defined by three different types of approaches: traditional post-Newtonian templates (Taylor-approximants), ``resummed'' post-Newtonian…
Grace-like polynomials
David Ruelle
Results of somewhat mysterious nature are known on the location of zeros of certain polynomials associated with statistical mechanics (Lee-Yang circle theorem) and also with graph…
Inconsistency of interacting, multi-graviton theories
Nicolas Boulanger, Thibault Damour, Leonardo Gualtieri +1
We investigate, in any spacetime dimension >=3, the problem of consistent couplings for a finite collection of massless, spin-2 fields described, in the free limit, by a sum of Pau…
Oscillatory Behaviour in Homogeneous String Cosmology Models
Thibault Damour, Marc Henneaux
Some spatially homogeneous Bianchi type I cosmological models filled with homogeneous ``electric'' -form fields are shown to mimic the never-ending oscillatory behaviour of gene…
Slowly rotating voids in cosmology
Tomas Dolezel, Jiri Bicak, Nathalie Deruelle
We consider a spacetime consisting of an empty void separated from an almost Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) dust universe by a spherically symmetric, slowly rotating…
Entropy production in quantum spin systems
David Ruelle
We consider a quantum spin system consisting of a finite subsystem connected to infinite reservoirs at different temperatures. In this setup we define nonequilibrium steady states…
Semiinfinite cohomology of Lie-* algebras
Sergey Arkhipov
We construct a geometric version of BRST cohomology complex of a chiral module over a Lie-* algebra using the language of differential graded Lie algebroids in the category of D-mo…
On the determination of the last stable orbit for circular general relativistic binaries at the third post-Newtonian approximation
Thibault Damour, Piotr Jaranowski, Gerhard Schaefer
We discuss the analytical determination of the location of the Last Stable Orbit (LSO) in circular general relativistic orbits of two point masses. We use several different ``resum…
Cosmic microwave background anisotropies seeded by incoherent sources
Alain Riazuelo, Nathalie Deruelle
The cosmic microwave background anisotropies produced by active seeds, such as topological defects, have been computed recently for a variety of models by a number of authors. In t…
Gravitational wave bursts from cosmic strings
Thibault Damour, Alexander Vilenkin
Cusps of cosmic strings emit strong beams of high-frequency gravitational waves (GW). As a consequence of these beams, the stochastic ensemble of gravitational waves generated by a…
Brane versus shell cosmologies in Einstein and Einstein-Gauss-Bonnet theories
Nathalie Deruelle, Tomas Dolezel
We first illustrate on a simple example how, in existing brane cosmological models, the connection of a 'bulk' region to its mirror image creates matter on the 'brane'. Next, we pr…
Existence and properties of p-tupling fixed points
Henri Epstein
We prove the existence of fixed points of p-tupling renormalization operators for interval and circle mappings having a critical point of arbitrary real degree r > 1. Some properti…
Renormalization in quantum field theory and the Riemann-Hilbert problem II: the -function, diffeomorphisms and the renormalization group
Alain Connes, Dirk Kreimer
We showed in part I (hep-th/9912092) that the Hopf algebra of Feynman graphs in a given QFT is the algebra of coordinates on a complex infinite dimensional Lie group …
