We study several different kinds of bound states built from D-branes and orientifolds. These states are to atoms what branonium — the bound state of a brane and its anti-brane — is to positronium, inasmuch as they typically involve a light brane bound to a much heavier object with conserved charges which forbid the system's decay. We find the fully relativistic motion of a probe Dp'-brane in the presence of source Dp-branes is integrable by quadratures. Keplerian conic sections are obtained for…

On Bouncing Brane-Worlds, S-branes and Branonium Cosmology

We present several higher-dimensional spacetimes for which observers living on 3-branes experience an induced metric which bounces. The classes of examples include boundary branes on generalized

D-brane dynamics and NS5 rings

We consider the classical motion of a probe D-brane moving in the background geometry of a ring of NS5 branes, assuming that the latter are non-dynamical. We analyse the solutions to the

Inflation from D3-brane motion in the background of D5-branes

We study inflation arising from the motion of a Bogomol'nyi-Prasad-Sommerfield D3-brane in the background of a stack of k parallel D5-branes. There are two scalar fields in this setup: (i) the radion

Tubular solutions in NS5-brane, Dp-brane and macroscopic strings backgrounds

We present our searches for the tubular bound states of a D2-brane with m D0-branes and n fundamental strings in the NS5-brane, Dp-brane or macroscopic strings background by solving the

Note About Non-BPS and BPS Dp-branes in Near Horizon Region of N Dk-Branes

In this paper we will consider the dynamics of BPS and non-BPS Dp-branes in the background of N Dk-branes. Our approach is based on an existence of the new symmetry of D-brane effective actions that

Anti-de Sitter D-branes in curved backgrounds

We investigate the properties of the AdS D1-branes which are the bound states of a curved D1-brane with n fundamental strings (F1) in the AdS3 spacetime, and the AdS D2-branes which are the axially

Non-Abelian phenomena on D-branes

A remarkable feature of D-branes is the appearance of a non-Abelian gauge theory in the description of several (nearly) coincident branes. This non-Abelian structure plays an important role in

Geometrical tachyon kinks and NS5 branes

We further investigate the NS5 ring background using the tachyon map. Mapping the radion fields to the rolling tachyon helps to explain the motion of a probe Dp-brane in this background. It turns out

Fuzzy sphere dynamics and non-abelian DBI in curved backgrounds

We consider the non-Abelian action for the dynamics of NDp'-branes in the background of MDp-branes, which parameterises a fuzzy sphere using the SU(2) algebra. We find that the curved background



The Inflationary Brane-Antibrane Universe

We show how the motion through the extra dimensions of a gas of branes and antibranes can, under certain circumstances, produce an era of inflation as seen by observers trapped on a 3-brane, with the

Brane inflation and reheating

We study inflation and reheating in a brane world model derived from type IIA string theory. This particular set-up is based on a model of string mediated supersymmetry breaking. The inflaton is one

Incidental brane defects

In the models of brane construction, the isometry of a compactified space might be broken by branes. In four-dimensional effective Lagrangian, the breaking of the isometry is seen as the spontaneous

Brane gases in the early Universe

Over the past decade it has become clear that fundamental strings are not the only fundamental degrees of freedom in string theory. D-branes are also part of the spectrum of fundamental states. In

Brane-antibrane inflation in orbifold and orientifold models

We analyse the cosmological implications of brane-antibrane systems in string-theoretic orbifold and orientifold models. In a class of realistic models, consistency conditions require branes and

Recombination of Intersecting D-Branes and Cosmological Inflation

We consider the interactions between Dp-branes intersecting at an arbitrary number of angles in the context of type-II string theory. For cosmology purposes we concentrate in the theory on 3,1 × T6.

Inflationary scenarios from branes at angles

We describe a simple mechanism that can lead to inflation within string-based brane-world scenarios. The idea is to start from a supersymmetric configuration with two parallel static Dp-branes, and

Pyrotechnic Universe

One of the central points of the ekpyrotic cosmological scenario based on Ho˘rava-Witten theory is that we live on a negative tension brane. However, the tension of the visible brane is positive in

The Lorentz force between D0 and D6 branes in string and M(atrix) theory

We use different techniques to analyze the system formed by a D0-brane and a D6- brane (with background gauge fields) in relative motion. In particular, using the closed string formalism of boosted
