Geometry of AdS black hole thermodynamics in extended phase space

open access: yesPhysics Letters B, 2021
We consider the geometry of anti-de-Sitter (AdS) black hole thermodynamics in four dimensions, where the equation of state in the extended phase space formalism allows explicit comparison with normal fluid systems.

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 ...

Thermal performance in heat exchangers by the irreversibility, effectiveness, and efficiency concepts using nanofluids [PDF]

open access: yesЖурнал інженерних наук, 2020
The objective of the work is to obtain the outlet temperatures of the fluids in a shell and tube heat exchanger. The second law of thermodynamics is applied through the concepts of efficiency, effectiveness, and irreversibility to analyze the results ...

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 ...

Thermodynamic volume of cosmological solitons

open access: yesPhysics Letters B, 2017
We present explicit expressions of the thermodynamic volume inside and outside the cosmological horizon of Eguchi-Hanson solitons in general odd dimensions. These quantities are calculable and well-defined regardless of whether or not the regularity condition for the soliton is imposed.

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.

Geometric Foundation of Thermo-Statistics, Phase Transitions, Second Law of Thermodynamics, but without Thermodynamic Limit [PDF]

open access: yes, 2002
A geometric foundation thermo-statistics is presented with the only axiomatic assumption of Boltzmann's principle S(E,N,V)=k\ln W. This relates the entropy to the geometric area e^{S(E,N,V)/k} of the manifold of constant energy in the finite-N-body phase
