Abstract

We propose an ansatz for a low-energy effective action {ital {bar S}} for a gravity-plus-matter system which is given by the usual action {ital S} (integral over space-time) {ital divided} by the space-time volume, {ital {bar S}}={ital S}/{ital V}. The resulting gravitational equation is independent of the value of the cosmological constant that is present in {ital S}. We suggest that {ital {bar S}} can be considered as an approximation for the effective action in the duality-symmetric'' closed-string theory in which the string coordinates {ital x} and their duals'' {ital {tilde x}} are treated as independent.

String duality transformations in f(R) gravity from Noether symmetry approach

Journal Article Capozziello, Salvatore; Gionti, Gabriele; Vernieri, Daniele - Journal of Cosmology and Astroparticle Physics

We select f(R) gravity models that undergo scale factor duality transformations. As a starting point, we consider the tree-level effective gravitational action of bosonic String Theory coupled with the dilaton field. This theory inherits the Busher's duality of its parent String Theory. Using conformal transformations of the metric tensor, it is possible to map the tree-level dilaton-graviton string effective action into f(R) gravity, relating the dilaton field to the Ricci scalar curvature. Furthermore, the duality can be framed under the standard of Noether symmetries and exact cosmological solutions are derived. Using suitable changes of variables, the string-based f(R) Lagrangians aremore »« less

Strings in cosmological and black hole backgrounds: Ring solutions

Journal Article de Vega, H; Egusquiza, I - Physical Review, D (Particles Fields); (United States)

The string equations of motion and constraints are solved for a ring-shaped ansatz in cosmological and black hole spacetimes. In FRW universes with arbitrary power behavior [[ital R]([ital X][sup 0])=[ital a][vert bar][ital X][sup 0][vert bar][sup [alpha]]], the asymptotic form of the solution is found for both [ital X][sup 0][r arrow]0 and [ital X][sup 0][r arrow][infinity] and we plot the numerical solution for all times. Right after the big bang ([ital X][sup 0]=0), the string energy decreases as [ital R]([ital X][sup 0])[sup [minus]1] and the string size grows as [ital R]([ital X][sup 0]) for 0[lt][alpha][lt]1 and as [ital X][sup 0] formore »« less

Chameleonic dilaton, nonequivalent frames, and the cosmological constant problem in quantum string theory

Journal Article Zanzi, Andrea - Physical Review. D, Particles Fields

The chameleonic behavior of the string theory dilaton is suggested. Some of the possible consequences of the chameleonic string dilaton are analyzed in detail. In particular, (1) we suggest a new stringy solution to the cosmological constant problem and (2) we point out the nonequivalence of different conformal frames at the quantum level. In order to obtain these results, we start taking into account the (strong coupling) string loop expansion in the string frame (S-frame), therefore the so-called form factors are present in the effective action. The correct dark energy scale is recovered in the Einstein frame (E-frame) without unnaturalmore »« less

Comparing S duality to string/(D{minus}5)-brane duality on actions

Journal Article Ryang, S - Physical Review, D

We realize the string/(D{minus}5)-brane duality on the action at the classical level between the T{sup 10{minus}D}-compactified heterotic string effective action and the (D{minus}5)-brane effective action in D dimensions by managing a Lagrange multiplier field. In the same way the S duality is also reconstructed as a dual transformation on the T{sup 6}-compactified heterotic string effective action. {copyright} {ital 1997} {ital The American Physical Society}

{ital U} duality and symplectic formulation of dilaton-axion gravity

Journal Article Galtsov, D; Kechkin, O - Physical Review, D

We study a bosonic four-dimensional effective action corresponding to the heterotic string compactified on a six-torus (dilaton-axion gravity with one vector field) on a curved space-time manifold possessing a timelike Killing vector field. Previously the existence of the SO(2,3){approximately}Sp(4,{ital R}) global symmetry ({ital U} duality) as well as the symmetric space property of the corresponding {sigma} model have been established following the Neugebauer-Kramer approach. Here we present an explicit form of the Sp(4,{ital R}) generators in terms of coset variables and construct a representation of the coset in terms of the physical target space coordinates. A complex symmetric 2{times}2 matrixmore »« less
