Finite Tsallis gravitational partition function for a system of galaxies

M Hameeda, B Pourhassan, MC Rocca… - General Relativity and …, 2021 - Springer
In this paper, we will study the large scale structure formation using the gravitational partition
function. We will assertively argue that the system of gravitating galaxies can be analyzed …

Gupta-feynman based quantum field theory of einstein's gravity

A Plastino, MC Rocca - Journal of Physics Communications, 2020 - iopscience.iop.org
This paper is an application to Einstein's gravity (EG) of the mathematics developed in

A review of the classical canonical ensemble treatment of Newton's gravitation

F Pennini, A Plastino, M Rocca, G Ferri - Entropy, 2019 - mdpi.com
It is common lore that the canonical gravitational partition function Z associated with the
classical Boltzmann-Gibbs (BG) exponential distribution cannot be built up because of …

Non-relativistic quantum field theory of Verlinde's emergent entropic gravity

A Plastino, MC Rocca - Annals of Physics, 2020 - Elsevier
Non relativistic quantum field theory propagators are indispensable tools in nuclear physics
and condensed matter theory. Here we apply them to gravitation, that is, discuss a non …

Two approaches that prove divergence free nature of non-local gravity

M Hameeda, B Pourhassan, MC Rocca… - The European Physical …, 2021 - Springer
This paper is an attempt to study the thermodynamics of the structure formation in the large
scale universe in the non local gravity using Boltzmann statistics and the Tsallis statistics …

Statistical mechanics description of an empirical scenario in which gravity was discussed when coupled to a harmonic oscillator

M Hameeda, A Plastinor, MC Rocca - International Journal of …, 2024 - World Scientific
We attempt to construct a (two-dimensional) statistical mechanics description of the scenario
in which the experiment in [T. Westphal et al., Nature 591, 225 (2021)] was made. It includes …

Quantum Theory of 3+ 1 Gravity and Dark Matter: A New Formulation of the Gupta-Feynman based Quantum Field Theory of 3+ 1 Einstein Gravity

H Mir, A Plastino, M Rocca - Journal of Holography Applications in …, 2024 - jhap.du.ac.ir
Gravitons and axions play an important role with regards to dark matter. Here, by appeal to
developments of Gupta and Feynman and using a novel mathematical theory based on …

Possible divergences in Tsallis' thermostatistics

A Plastino, MC Rocca - Europhysics Letters, 2014 - iopscience.iop.org
Lutsko and Boon have shown via elegant theoretical reasoning (EPL, 95 (2011) 20006), that
Tsallis' thermostatistics is affected by divergence problems. We explicitly verify such fact in …
