An analytical anisotropic compact stellar model of embedding class I
Lipi Baskey, Shyam Das, Farook Rahaman
A class of solutions of Einstein field equations satisfying Karmarkar embedding condition is presented which could describe static, spherical fluid configurations, and could serve…
A Dynamical System Analysis of cosmic evolution with coupled phantom dark energy with dark matter
Soumya Chakraborty, Sudip Mishra, Subenoy Chakraborty
The present work is an example of the application of the dynamical system analysis in the context of cosmology. Here cosmic evolution is considered in the background of homogeneous…
Does emergent scenario in Hořava-Lifshitz Gravity demand a ghost field?
Akash Bose, Subenoy Chakraborty
The non-singular model of the Universe i.e. emergent scenario is now very well known in cosmology. In Einstein gravity such type of singularity free solution is possible in the con…
FIRST winged radio galaxies with X and Z symmetry
Soumen Bera, Sabyasachi Pal, Tapan K. Sasmal +1
X-shaped radio galaxies are a subclass of radio sources that exhibit a pair of secondary low surface brightness radio lobes oriented at an angle to the primary high surface brightn…
Chaos and Complexity from Quantum Neural Network: A study with Diffusion Metric in Machine Learning
Sayantan Choudhury, Ankan Dutta, Debisree Ray
In this work, our prime objective is to study the phenomena of quantum chaos and complexity in the machine learning dynamics of Quantum Neural Network (QNN). A Parameterized Quantu…
Cosmic evolution in f(T) gravity theory
Akash Bose, Subenoy Chakraborty
The paper deals with cosmology in modified f(T) gravity theory. With some phenomenological choices for the function f(T) it is possible to have cosmological solutions describing di…
