Description
Regular phantom black holes (RPBHs) hold theoretical and observational significance due to their incorporation of the phantom scalar field, an alternative to the cosmological constant, and some of their thermodynamical properties have also been studied. Several RPBH properties, such as the horizon radius, entropy, etc., rely on the scale parameter 𝑏𝑏. Because of the distinct structure compared to Schwarzschild-like metrics, a novel function of the scale parameter is necessary to articulate the relationships between thermodynamic variables. In this work, we have calculated the quantum corrections due to small statistical thermal fluctuations in various thermodynamic quantities of RPBH, such as entropy, Helmholtz free energy, internal energy, etc. The thermodynamic quantities of regular phantom black holes are perturbed because of minute statistical fluctuations around the equilibrium; in the present work, we have calculated the corrected thermodynamics of RPBH because of small statistical thermal fluctuations. We have plotted curves of several thermodynamical quantities, such as entropy, free energy, specific heat, etc., against the RPBH event horizon radius and then analysed the behaviour and variation of these curves of corrected thermodynamical quantities as a function of black hole event horizon radius.
