Thermodynamics of Reissner-Nordst\"orm black bounce black hole

Black bounce black holes are modification of classical black hole solutions that regularize the singularity by using a bouncing parameter. In our work, we explored the thermodynamics of Reissner-Nordst\"orm black bounce black hole and determined thermodynamic properties such as entropy, mass, temperature, free energy and heat capacity. Along with this, we investigated the interconnection between entropy and other thermodynamic properties through graphical analysis. This provides insight into studying the extended phase space of the particular black hole. We further determined the logarithmic correction to entropy term.

Thermodynamics and Spectroscopy of Schwarzschild black hole surrounded by Quintessence

The thermodynamic and spectroscopic behaviour of Schwarzschild black hole surrounded by quintessence are studied. We have derived the thermodynamic quantities and studied their behaviour for different values of quintessence parameter. We put the background space-time into the Kruskal-like coordinate to find the period with respect to Elucidean time. Also assuming that the adiabatic invariant obeys Bohr-Sommerfeld quantization rule, detailed study of area spectrum and entropy spectrum have been done for special cases of the quintessece state parameter. We find that the spectra are equally spaced.
