Lanczos–Lovelock models of gravity

T Padmanabhan, D Kothawala - Physics Reports, 2013 - Elsevier
Lanczos–Lovelock models of gravity represent a natural and elegant generalization of
Einstein's theory of gravity to higher dimensions. They are characterized by the fact that the …

Thermodynamical aspects of gravity: new insights

T Padmanabhan - Reports on Progress in Physics, 2010 - singtest.iopscience.iop.org
The fact that one can associate thermodynamic properties with horizons brings together
principles of quantum theory, gravitation and thermodynamics and possibly offers a window …

Thermodynamics in f (R, T) theory of gravity

M Sharif, M Zubair - Journal of Cosmology and Astroparticle …, 2012 - iopscience.iop.org
A non-equilibrium picture of thermodynamics is discussed at the apparent horizon of FRW
universe in f (R, T) gravity, where R is the Ricci scalar and T is the trace of the energy …

Emergent perspective of gravity and dark energy

T Padmanabhan - Research in astronomy and astrophysics, 2012 - iopscience.iop.org
There is sufficient amount of internal evidence in the nature of gravitational theories to
indicate that gravity is an emergent phenomenon like, eg, elasticity. Such an emergent …

Thermodynamics and cosmological reconstruction in f (T, B) gravity

S Bahamonde, M Zubair, G Abbas - Physics of the dark universe, 2018 - Elsevier
Recently, it was formulated a teleparallel theory called f (T, B) gravity which connects both f
(T) and f (R) under suitable limits. In this theory, the function in the action is assumed to …

Thermodynamics of phase transition in higher dimensional AdS black holes

R Banerjee, D Roychowdhury - Journal of High Energy Physics, 2011 - Springer
We investigate the thermodynamics of phase transition for (n+ 1) dimensional Reissner
Nordstrom (RN)-AdS black holes using a grand canonical ensemble. This phase transition is …

Comprehensive analysis of a non-singular bounce in f (R, T) gravitation

S Bhattacharjee, PK Sahoo - Physics of the Dark Universe, 2020 - Elsevier
The present paper is devoted to the study of bouncing cosmology in f (R, T) modified gravity
where we presume f (R, T)= R+ 2 λ T, with R the Ricci scalar, T the trace of energy …

Holographic Lovelock gravities and black holes

J de Boer, M Kulaxizi, A Parnachev - Journal of High Energy Physics, 2010 - Springer
We study holographic implications of Lovelock gravities in AdS spacetimes. For a generic
Lovelock gravity in arbitrary spacetime dimensions we formulate the existence condition of …
