Anisotropic compact star with a linear pressure-density relationship
Shyam Das, Bikram Keshari Parida, Koushik Chakraborty +1
We present a model of compact astrophysical object under General Theory of Relativity using the anisotropic extension of Tolman IV solution. The anisotropy function, derived from t…
Anisotropic generalization of Buchdahl bound for specific stellar models
Ranjan Sharma, Arpita Ghosh, Soumik Bhattacharya +1
Anisotropy is one factor that appears to be significantly important in the studies of relativistic compact stars. In this paper, we make a generalization of the Buchdahl limit by i…

Restricted Distribution of Quantum Correlations in Bilocal Network
Kaushiki Mukherjee, Biswajit Paul, Debasis Sarkar
Analyzing shareability of correlations arising in any physical theory may be considered as a fruitful technique of studying the theory. Our present topic of discussion involves an…
Nontrilocality: Exploiting nonlocality from three particle systems
Kaushiki Mukherjee, Biswajit Paul, Debasis Sarkar
In Phys. Rev. Lett. \textbf{104},170401 (2010), Branciard \textit{e.t al.} first characterized the correlations arising in an entanglement swapping network under the assumption tha…
