Oscillation of cosmic space in the background of two interacting tachyonic BIons

TL;DR

This paper explores how interactions between two tachyonic BIons influence cosmic space oscillations, revealing that their associated universes expand and contract oppositely depending on tachyonic fields and wormhole parameters.

Contribution

It introduces a model of interacting tachyonic BIons affecting cosmic evolution, highlighting new regions with opposite cosmic behaviors due to wormhole interactions.

Findings

Cosmic parameters in interacting BIons act oppositely in different regions.

Universe expansion in one region corresponds to contraction in the other.

Evolution depends on tachyonic fields, brane separation, and wormhole throat size.

Abstract

When a brane-anti-brane system includes two tachyons, each of them produces a BIoninc wormhole. These wormholes interact with each other and form 4 regions. Two of the regions are related to the independent BIons which have been considered previously. However, two new regions correspond to the interacting BIons in which the cosmic parameters act oppositely to each other. We obtain the Hubble parameter and energy density of the universes in the new regions and show that by expanding a universe in one region, the universe in the other region contracts. Also, the evolution of the universes depend on the tachyonic fields, the separation between the branes and the size of the throats of the bionic wormholes.
