We construct an n-dimensional Born-Infeld-type gravity theory that has the same properties as Einstein's gravity in terms of the vacuum and particle content: Namely, the theory has a unique viable vacuum (maximally symmetric solution) and a single massless unitary spin-2 graviton about this vacuum. The Born-Infeld gravity, in some sense, is the most natural, minimal generalization of Einstein's gravity with a better UV behavior and hence is a potentially less singular theory at small distances. The Gauss-Bonnet combination plays a nontrivial role in the construction of the theory. As an extreme example, we consider the infinite-dimensional limit where an interesting exponential gravity arises.

Born-Infeld gravity with a massless graviton in four dimensions Guellue, Ibrahim; Sisman, Tahsin Cagri; Tekin, Bayram (2015-02-03) We construct Born-Infeld (BI) type gravity theories which describe tree-level unitary (nonghost and nontachyonic) massless spin-2 modes around their maximally symmetric vacua in four dimensions. Building unitary BI actions around flat vacuum is straightforward, but this is a complicated task around (anti)-de Sitter backgrounds. In this work, we solve the issue and give details of constructing perturbatively viable determinantal BI theories. It is interesting that the Gauss-Bonnet combination, which is a tot...
Born-Infeld gravity theories in D-dimensions Şişman, Tahsin Çağrı; Tekin, Bayram; Department of Physics (2012) Born-Infeld gravity proposed by Deser and Gibbons takes its origin from two ideas: Born-Infeld electrodynamics and Eddington's gravitational action. The theory is defined with a determinantal action involving the Ricci tensor as in the Eddington's theory; however, in contrast, the independent variable is the metric as in Einstein's gravity and the action is constructed in analogy with the action of the Born-Infeld electrodynamics. Main challenge in defining a Born-Infeld type gravity is obtaining a unitary ...
Phase transition in compact QED3 and the Josephson junction Onemli, VK; Tas, M; Tekin, Bayram (2001-08-01) We study the finite temperature phase transition in 2+1 dimensional compact QED and its dual theory: Josephson junction. Duality of these theories at zero temperature was established long time ago in [1]. Phase transition in compact QED is well studied thus we employ the 'duality' to study the superconductivity phase transition in a Josephson junction. For a thick junction we obtain a critical temperature in terms of the geometrical properties of the junction.
Electrically charged vortex solutions in Born-Infeld theory with a Chern-Simons term Çimşit, Mustafa; İpekoğlu, Yusuf; Department of Physics (2003) In this thesis, we considered electrically charged vortex solutions of Born- Infeld Chern-Simons gauge theory in 2+1 dimensions, with a sixth order charged scalar eld potential. For this purpose, rst Nielsen-Olesen vortex solutions are extensively reviewed. Then, Born-Infeld and Chern-Simons theories are summarized. Finally, vortex solutions are obtained for the Born-Infeld-Higgs system with a Chern-Simons term. These solutions are analyzed numerically, comparing their properties with Nielsen-Olesen vortices.
Entropy in Born-Infeld gravity Alıcı, Gökçen Deniz; Kürekci, Şahin; Tekin, Bayram (2017-12-28) There is a class of higher derivative gravity theories that are in some sense natural extensions of cosmological Einstein's gravity with a unique maximally symmetric classical vacuum and only a massless spin-2 excitation about the vacuum and no other perturbative modes. These theories are of the Born-Infeld determinant form. We show that the macroscopic dynamical entropy as defined by Wald for bifurcate Killing horizons in these theories are equivalent to the geometric Bekenstein-Hawking entropy (or more pr...
