The mathematical structure of innovation

Thomas M. A. Fink, Ali Teimouri

Despite our familiarity with specific technologies, the origin of new technologies remains mysterious. Are new technologies made from scratch, or are they built up recursively from…

On Aspects of Infinite Derivatives Field Theories & Infinite Derivative Gravity

Ali Teimouri

Infinite derivative theory of gravity is a modification to the general theory of relativity. Such modification maintains the massless graviton as the only true physical degree of f…

Machine learning in sentiment reconstruction of the simulated stock market

Mikhail Goykhman, Ali Teimouri

In this paper we continue the study of the simulated stock market framework defined by the driving sentiment processes. We focus on the market environment driven by the buy/sell tr…

Entropy of non-local gravity

Ali Teimouri

For higher derivative theories of gravity, it is possible to write the action in terms of auxiliary fields. In such case, one can show that the equations of motion for both actions…

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…

Rotating black hole and entropy for modified theories of gravity

Spyridon Talaganis, Ali Teimouri

In this paper we obtain the entropy of the Kerr black hole for a number of modified theories of gravity. We show that as long as the deviation from Einstein Hilbert term consists p…

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…

Generalised Boundary Terms for Higher Derivative Theories of Gravity

Ali Teimouri, Spyridon Talaganis, James Edholm +1

In this paper we wish to find the corresponding Gibbons-Hawking-York term for the most general quadratic in curvature gravity by using Coframe slicing within the Arnowitt-Deser-Mis…

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…
