The FRW Universe as a van der Waals-like Thermodynamic Heat Engine
Haximjan Abdusattar, Saül Tomàs Vázquez
It is well known that the Friedmann-Robertson-Walker (FRW) universe is a dynamical spacetime, and it has thermodynamics embodied on the apparent horizon. Notably, it also possesses…
Investigating Graviton Mass Effects on Black Hole Lensing in dRGT Massive Gravity
Haximjan Abdusattar, Yu-Xuan Han, Abdujappar Rusul +1
In this paper, we delve into the gravitational lensing and photon trajectories in the vicinity of non-asymptotically flat black hole spacetimes within the framework of dRGT massive…
Thermodynamic curvature in phase transitions for Hayward AdS black hole
Haximjan Abdusattar
We investigate - criticality, with a focus on Ruppeiner geometry, in the extended phase space of Hayward anti-de Sitter (AdS) black holes. Through thermodynamic analysis, we…
Insight into the Microstructures of Black Holes with Quantum-Triggered Violations
Haximjan Abdusattar
In this study, we investigate the microstructures of a charged AdS (Anti-de Sitter) black hole exhibiting quantum anomalies through the lens of Ruppeiner geometry. Previous researc…
Nucleon axial form factors in generalized nonlocal chiral effective theory
Y. Salamu, Haximjan Abdusattar
In this work, we first investigate the chiral transformation properties of the nonlocal pion field operator and construct a generalized nonlocal chiral Lagrangian that is invariant…
Thermodynamics of the arbitrary dimensional FRW universe: Joule-Thomson expansion
Haximjan Abdusattar, Shi-Bei Kong, Minawar Omar +1
In this paper, we investigate the thermodynamics especially the Joule-Thomson expansion of the -dimensional FRW (Friedmann-Robertson-Walker) universe with a perfect fluid. We de…
