Scale of non-locality for a system of particles
Spyridon Talaganis, Ali Teimouri
Higher derivative theories of gravity are associated with a mass scale to insure the correct dimensionality of the covariant derivatives. This mass scale is known as the scale of n…
Entropic f(R) Gravity
Ali Teimouri
In this short paper we follow the entropic gravity approach and demonstrate how \(f(R)\) theories of gravity can be emergent. This is done by introducing an effective gravitational…
Hamiltonian Analysis for Infinite Derivative Field Theories and Gravity
Spyridon Talaganis, Ali Teimouri
Typically higher-derivative theories are unstable. Instabilities manifest themselves from extra propagating degrees of freedom, which are unphysical. In this paper, we will investi…
Non-local gravity in D-dimensions: Propagator, entropy and bouncing Cosmology
Aindriu Conroy, Anupam Mazumdar, Spyridon Talaganis +1
We present the graviton propagator for an infinite derivative, -dimensional, non-local action, up to quadratic order in curvature around a Minkowski background, and discuss the…
Wald's gravitational entropy for ghost-free, infinite derivative theories of Gravity
Aindriú Conroy, Anupam Mazumdar, Ali Teimouri
In this paper, we demonstrate that the Wald's entropy for any spherically symmetric blackhole within an infinite derivative theory of gravity is determined solely by the area law.…
Generalised Quadratic Curvature, Non-Local Infrared Modifications of Gravity and Newtonian Potentials
Aindriu Conroy, Tomi Koivisto, Anupam Mazumdar +1
Metric theories of gravity are studied, beginning with a general action that is quadratic in curvature and allows infinite inverse powers of the d'Alembertian operator, resulting i…
Correlators of Circular Wilson Loops from Holography
Adi Armoni, Maurizio Piai, Ali Teimouri
We study the correlators of two circular Wilson loops of different radii at strong coupling. In our setup one Wilson loop is located inside the other. We use holography to calculat…
