Joule-Thomson expansion of Born-Infeld AdS black holes

Shihao Bi et al.

Summary: This paper investigates the Joule-Thomson expansion of Born-Infeld AdS black holes in the extended phase space, discussing detail the Joule-Thomson coefficient, inversion curves, and isenthalpic curves using a 4-dimensional black hole. Critical points and curves in the T - P plane are analyzed with different parameters beta and charge Q. It is found that the missing negative slope is still conserved in Born-Infeld black holes, and the results are extended to higher dimensions beyond 4. Comparisons are made on critical temperatures and inversion temperature minima, showing a ratio of asymptotically 1/2 as Q increases or beta approaches infinity, consistent with previous findings in higher dimensions.

Heat engine efficiency and Joule-Thomson expansion of nonlinear charged AdS black hole in massive gravity

Cao H. Nam

Summary: This paper investigates the heat engine and Joule-Thomson expansion of a charged AdS black hole in the context of nonlinear electrodynamics and massive gravity. Analytical expressions for efficiency in different limits and various parameters were obtained for the black hole heat engine. The effects of nonlinear electrodynamics and massive gravity on the efficiency of the heat engine and Joule-Thomson expansion of the black hole were detailed.

Joule-Thomson expansion of regular Bardeen AdS black hole surrounded by static anisotropic matter field

K. Rajani et al.

Summary: This paper investigates the anisotropy of Bardeen black hole in a static anisotropic matter field and analyzes its Joule-Thomson expansion. By studying the pressure anisotropy, equation of state, and pressure variation with radial coordinate, as well as treating the cosmological constant as a thermodynamic pressure and deriving the equation of state connecting Hawking temperature and black hole parameters, the paper explores the effects of anisotropic matter field on JT expansion.

Overcounting of interior excitations: a resolution to the bags of gold paradox in AdS

Joydeep Chakravarty

Summary: This work investigates how single-sided and eternal black holes can contain a vast number of semiclassical excitations in their interior, proposing a new solution to resolve the paradox in entropy. By describing the interior of black holes in Hilbert space, the resolution of the paradox arising from the orthogonal relationships between these excitations is provided.
