The fallacy of Oppenheimer Snyder Collapse: no general relativistic Collapse at all, no black hole, no physical singularity
Abhas Mitra
By applying Birkhoff's theorem to the problem of the general relativistic collapse of a uniform density dust, we directly show that the density of the dust even when its prop…
Magnetron Sputtered NbN Films with Nb Interlayer
Kulwant Singh, A. C. Bidaye, A. K. Suri
NbN films were deposited on SS substrates by reactive DC magnetron sputtering at various N2 flow rates and substrate biasing. Effect of N2 flow rate and substrate biasing has been…
No uniform density star in general relativity
Abhas Mitra
As per general relativity (GR), there cannot be any superluminal propagation of energy. And thus, the sound speed in a continuous medium, , must be subluminal. Ho…
Effect of B-site Dopants on Magnetic and Transport Properties of LaSrCoRuO
P. S. Ramu Murthy, K. R. Priolkar, P. A. Bhobe +3
Effect of Co, Ru and Cu substitution at B and B' sites on the magnetic and transport properties of LaSrCoRuO have been investigated. All the doped compositions crystallize in t…
Energy dependence of elliptic flow from heavy-ion collision models
Md. Nasim, Lokesh Kumar, Pawan Kumar Netrakanti +1
We have compared the experimental data on charged particle elliptic flow parameter (v2) in Au+Au collisions at midrapidity for \surd sNN = 9.2, 19.6, 62.4 and 200 GeV with results…
meson photoproduction on proton
Swapan Das
The cross section is estimated for the invariant mass distribution in the reaction in the GeV region. This reaction is assumed to proceed through the formation of…
