We present Poincare-invariant domain wall (''three-brane'') solutions to some five-dimensional effective theories which can arise naturally in string theory. In particular, we find theories where Poincare-invariant solutions exist for arbitrary values of the brane tension, for certain restricted forms of the bulk interactions. We describe examples in string theory where it would be natural for the quantum corrections to the tension of the brane (arising from quantum fluctuations of modes with… Expand
Bounds on curved domain walls in 5D gravity
The authors discuss maximally symmetric curved deformations of the flat domain wall solutions of five-dimensional dilaton gravity that appeared in a recent approach to the cosmological constantExpand
Self-T-dual brane cosmology and the cosmological constant problem
We consider a codimension-one brane embedded in a gravity-dilaton bulk action, whose symmetries are compatible with T-duality along the space-like directions parallel to the brane, and the bulkExpand
Brane Cosmology From Heterotic String Theory
We consider brane cosmologies within the context of five-dimensional effective actions with $${\cal O}(\alpha^{\prime})$$ higher curvature corrections. The actions are compatible with bulk stringExpand
Codimension-two branes in six-dimensional supergravity and the cosmological constant problem
We investigate in detail recent suggestions that codimension-two braneworlds in six-dimensional supergravity might circumvent Weinberg's no-go theorem for self-tuning of the cosmological constant.Expand

The cosmological constant in the brane world of string theory on S1/Z2

Brane world generation by matter and gravity
We present a non-compact 4 + 1 dimensional model with a local strong four-fermion interaction supplementing it with gravity. In the strong coupling regime it reveals the spontaneous translationalExpand
Holographic self-tuning of the cosmological constant
A bstractWe propose a brane-world setup based on gauge/gravity duality in which the four-dimensional cosmological constant is set to zero by a dynamical self-adjustment mechanism. The bulk containsExpand
We consider, in five dimensions, the effective action from heterotic string which includes quantum gravity corrections up to (α′)2. The expansion, in the string frame, is in terms of |α′R|, where RExpand
Scaling solutions to 6D gauged chiral supergravity
We construct explicitly time-dependent exact solutions to the field equations of six-dimensional (6D) gauged chiral supergravity, compactified to 4D in the presence of up to two three-branes situatedExpand


Self-dual strings and N = 2 supersymmetric field theory
We show how the Riemann surfaceof N = 2 Yang-Mills field theory arises in type II string compactifications on Calabi-Yau threefolds. The relevant local geometry is given by fibrations of ALE spaces.Expand
Universal aspects of gravity localized on thick branes
Abstract We study gravity in backgrounds that are smooth generalizations of the Randall–Sundrum model, with and without scalar fields. These generalizations include three-branes in higher dimensionalExpand

Small instantons in string theory
Abstract A long-standing puzzle about the heterotic string has been what happens when an instanton shrinks to zero size. It is argued here that the answer at the quantum level is that an extra SU (2)Expand
On RG-flow and the Cosmological Constant
The AdS/CFT correspondence implies that the effective action of certain strongly coupled large $N$ gauge theories satisfy the Hamilton-Jacobi equation of 5d gravity. Using an analogy with theExpand
