Ja n 20 06 Origin of strings Richard Atkins

چکیده
It is shown that strings result naturally from considerations of gravitation. First, a Lorentz-covariant field formulation of gravitation in flat spacetime is developed. The requirement of covariance and the existence of a potential leads to an essentially unique theory based upon a symmetric, traceless, two-index tensor. The gravitational field possesses gauge invariance described by a second-order covariant derivative defining an associated differential geometry. The concepts of parallelism and parallel transport lead to string-like constructions.

We investigate the Gregory-Laflamme instability for black strings carrying KK-momentum along the internal direction. We demonstrate a simple kinematical relation between the thresholds of the classical instability for the boosted and static black strings. We also find that Sorkin’s critical dimension depends on the internal velocity and in fact disappears for sufficiently large boosts. Our anal...

In this paper we consider tree-level scattering in the minimal N = 4 topological string and show that a large class of N -point functions can be recast in terms of corresponding amplitudes in the (1, k) minimal bosonic string. This suggests a non-trivial relation between the minimal N = 4 topological strings, the (1, k) minimal bosonic strings and their corresponding ADE matrix models. This rel...

We compute the S-matrix, for the scattering of two string states, on a noncommutative D3brane in a path integral formalism. Our analysis attempts to resolve the issue of “imaginary string”, originally raised by ’t Hooft in a point-particle scattering at Planck energy, by incorporating a notion of signature change on an emerging semi-classical D-string in the theory.

A supersymmetric hybrid potential model with low energy supersymmetry breaking scale (MS ∼ 1 − 10Tev) is presented for both dark matter and dark energy. Cold dark matter is associated with a light modulus field (∼ 10−100Mev) undergoing coherent oscillations around a saddle point false vacuum with the presently observed energy density (ρ0 ∼ 10 eV ). The latter is generated by its coupling to a l...
