Handhika S. Ramadhan, Brian A. Cahyo, and Muhammad Iqbal
TL;DR
This paper explores flux compactifications in Einstein-Born-Infeld theories, showing that nonlinearity has minimal impact on Einstein-Maxwell models but destabilizes certain compactifications in Einstein-Higgs models.
Contribution
It extends flux compactification analysis to Einstein-Born-Infeld theories and uncovers stability effects unique to nonlinear Born-Infeld dynamics.
Findings
Born-Infeld does not alter Einstein-Maxwell flux compactifications significantly.
In Einstein-Higgs models, Born-Infeld nonlinearity causes instability for q>1.
The study highlights the role of nonlinearity in higher-dimensional stability.
Abstract
We investigate the flux compactification mechanism in simple toy models of Einstein-Born-Infeld theories. These are the direct generalizations of the Einstein-Maxwell flux compactifications that recently gained fame as a toy model for tunneling in the landscape. Our investigation reveals that the Born-Infeld form does not significantly modify the qualitative result of the Einstein-Maxwell theory. for the case of Einstein-Higgs theory, however, we found that the effect of Born-Infeld nonlinearity is to render all q>1 extradimensional compactification unstable against semiclassical tunneling to nothing.
