Thermodynamics, statistical mechanics and the vanishing pore width limit of confined fluids

open access: yesCommunications Physics, 2023
Temperature, particle number and volume are the independent variables of the Helmholtz free energy for a bulk fluid. For a fluid confined in a slit pore between two walls, they are usually complemented by the surface area.

Fidelity susceptibility as holographic PV-criticality

open access: yesPhysics Letters B, 2017
It is well known that entropy can be used to holographically establish a connection among geometry, thermodynamics and information theory. In this paper, we will use complexity to holographically establish a connection among geometry, thermodynamics and ...

Phase Structure of Non-Commutative Field Theories and Spinning Brane Bound States [PDF]

open access: yes, 1999
General spinning brane bound states are constructed, along with their near-horizon limits which are relevant as dual descriptions of non-commutative field theories.

A Machine Learning Approach to Predicting the Heat Convection and Thermodynamics of an External Flow of Hybrid Nanofluid

open access: yesJournal of energy resources technology, 2021
This study numerically investigates heat convection and entropy generation in a hybrid nanofluid (Al2O3–Cu–water) flowing around a cylinder embedded in porous media.

Geometric and thermodynamic volume of hairy black branes

open access: yesJournal of High Energy Physics, 2020
With the objective to generalize previous results found for a handful of explicit solutions, we study the extended thermodynamics of a black brane with minimally coupled scalar hair in D-dimensional asymptotically anti-de Sitter spacetimes.

Thermodynamical properties of the Universe with dark energy [PDF]

open access: yes, 2006
We have investigated the thermodynamical properties of the Universe with dark energy. Adopting the usual assumption in deriving the constant co-moving entropy density that the physical volume and the temperature are independent, we observed some strange ...

Black hole chemistry: thermodynamics with Lambda [PDF]

open access: yes, 2016
We review recent developments on the thermodynamics of black holes in extended phase space, where the cosmological constant is interpreted as thermodynamic pressure and treated as a thermodynamic variable in its own right.

Impact of thermodynamic hypotheses on the calculation of the quantity of CO2 stored in a saline aquifer [PDF]

open access: yesMATEC Web of Conferences, 2023
The aim of this paper is to study the impact of thermodynamics models on the CO2 storage capacity of an aquifer, by using modelling and simulation of transport phenomena in porous media.

Thermodynamics and Chemistry of the Early Universe [PDF]

open access: yes, 2018
The interplay between chemistry and thermodynamics determines the final outcome of the process of gravitational collapse and sets the conditions for the formation of the first cosmological objects, including primordial supermassive black holes.

Potentiometric MRI of a Superconcentrated Lithium Electrolyte: Testing the Irreversible Thermodynamics Approach

open access: yesACS Energy Letters, 2021
Superconcentrated electrolytes, being highly thermodynamically nonideal, provide a stringent proving ground for continuum transport theories. Herein, we test an ostensibly complete model of LiPF6 in ethyl-methyl carbonate (EMC) based on the Onsager ...
