Starobinsky–Bel–Robinson Gravity

چکیده
A novel superstring-inspired gravitational theory in four spacetime dimensions is proposed as a sum of the modified $(R+\alpha R^2)$ gravity motivated by Starobinsky inflation and Bel-Robinson-tensor-squared term eleven-dimensional M-theory dimensionally reduced to dimensions. The Starobinsky-Bel-Robinson action has only two parameters, which makes it suitable for verifiable physical applications black hole physics, cosmological Hawking radiation early universe.

Liouville gravity from Einstein gravity
We show that Liouville gravity arises as the limit of pure Einstein gravity in 2+ ε dimensions as ε goes to zero, provided Newton’s constant scales with ε. Our procedure – spherical reduction, dualization, limit, dualizing back – passes several consistency tests: geometric properties, interactions with matter and the Bekenstein-Hawking entropy are as expected from Einstein gravity. Platinum Jub...
متن کاملLineal gravity from planar gravity.
We show how to obtain the two dimensional black hole action by a dimensional reduction of the three dimensional Einstein action with a non-zero cosmological constant. Starting from the Chern-Simons formulation of 2+1 gravity, we obtain the 1+1-dimensional gauge formulation given by Verlinde. Remarkably, the proposed reduction shares the relevant features of the formulation of Cangemi and Jackiw...
متن کاملChiral Gravity, Log Gravity, and Extremal CFT
We show that the linearization of all exact solutions of classical chiral gravity around the AdS3 vacuum have positive energy. Non-chiral and negative-energy solutions of the linearized equations are infrared divergent at second order, and so are removed from the spectrum. In other words, chirality is confined and the equations of motion have linearization instabilities. We prove that the only ...
متن کاملDualities and Emergent Gravity: Gauge/Gravity Duality
In this paper I develop a framework for relating dualities and emergence: two notions that are close to each other but also exclude one another. I adopt the conception of duality as ‘isomorphism’, from the physics literature, cashing it out in terms of three conditions. These three conditions prompt two conceptually different ways in which a duality can be modified to make room for emergence; a...
متن کاملGravity Resonance Spectroscopy and Einstein- Cartan Gravity
The qBounce experiment offers a new way of looking at gravitation based on quantum interference. An ultracold neutron is reflected in well-defined quantum states in the gravity potential of the Earth by a mirror, which allows to apply the concept of gravity resonance spectroscopy (GRS). This experiment with neutrons gives access to all gravity parameters as the dependences on distance, mass, cu...
