Joule-Thomson Effect and Geodesic Structure of Charged AdS Black Holes in f(R,T) Coupled with Nonlinear Electrodynamics

Shyamalee Bora, Dhruba Jyoti Gogoi, Pralay Kumar Karmakar

We herein study both the Joule-Thomson (JT) expansion process and the geodesic properties of a charged anti-de Sitter (AdS) black hole arising in modified gravity with nonlinear el…

Stability and wave dynamics in polytropic Eddington-inspired Born-Infeld gravitating solar plasmas

Souvik Das, Pralay Kumar Karmakar

We investigate the influence of nonlinear gravity corrections, arising from the Eddington-inspired Born-Infeld (EiBI) theory on wave dynamics, stability, and energy transport proce…

Impact of Thermodynamic Corrections on the Stability of Hayward-Anti de Sitter Black Hole Surrounded by a Fluid of Strings

Shyamalee Bora, Dhruba Jyoti Gogoi, Pralay Kumar Karmakar

We explore the modified thermodynamics of a Hayward-Anti de Sitter (H-AdS) black hole in atypical conditions, incorporating a string fluid, Hayward regularisation, and quantum entr…

An electric circuital analysis of laboratory plasma sheath fluctuations and propagations

Subham Dutta, Pralay Kumar Karmakar

The effective inductive (L), capacitive (C), and resistive (R) behavior of a plasma sheath in a conjoint coupled form is well familiar among plasma physics communities. A dynamic s…
