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…
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.…
Spinning Black Hole in a Fluid
Surojit Dalui, Arpan Krishna Mitra, Deeshani Mitra +1
In this paper, we propose a new Analogue Gravity example - a spinning (or Kerr) Black Hole in an extended fluid model. The fluid model receives Berry curvature contributions and ap…
Acoustic Kerr Metric in Analogue Gravity
Deeshani Mitra, Surojit Dalui, Subir Ghosh +1
The present paper is based on a previous work (involving two of the present authors) where a generalized fluid dynamical model was proposed. The underlying symplectic structure of…
Barrow Holographic Dark Energy in Brane World Cosmology
Anirban Chanda, Arpan Krishna Mitra, Souvik Ghose +2
Cosmological features of Barrow Holographic Dark Energy (BHDE), a recent generalization of original Holographic dark energy with a richer structure, are studied in the context of D…
Simulating gravity in rotational flow
Satadal Datta, Arpan Krishna Mitra
We consider classical fluids in non-relativistic framework. The flow is considered to be barotropic, inviscid and rotational. We study the linear perturbations over a steady state…
