On the spin dependence of the emergent gravity phenomena as observed in axially symmetric black hole accretion with spatially varying adiabatic index
Kalyanbrata Pal, Souvik Ghose, Ripon Sk +2
The present work addresses an axisymmetrically accreting black hole system from three perspectives: the astrophysical, the dynamical systems, and the emergent gravity standpoint. S…

Non-Commutative fluid: an alternative source of cosmic acceleration
Raj Kumar Das, Arpan Krishna Mitra
We present a novel formulation for the Hubble parameter derived from Newtonian cosmology, incorporating non-commutative fluid dynamics through a deformed Poisson bracket structure.…

Dynamical analog spacetimes from nonlinear perturbations in a topological material
Surajit Das, Surojit Dalui, Hrishit Banerjee +1
Emergent spacetime analogs in condensed matter systems have opened a fascinating window into simulating aspects of gravitational physics in controlled laboratory environments. In t…
