Consequences of f(R)-theories of gravity on gravitational leptogenesis
G. Lambiase, S. Mohanty, L. Pizza
f(R)-theories of gravity are reviewed in the framework of the matter-antimatter asymmetry in the Universe. The asymmetry is generated by the gravitational coupling of heavy (Majora…
Electric dipole polarizabilities of alkali metal ions from perturbed relativistic coupled-cluster theory
S. Chattopadhyay, B. K. Mani, D. Angom
We use the perturbed relativistic coupled-cluster theory to compute the static electric dipole polarizabilities of the singly ionized alkali atoms, namely, Na, , Rb, Cs…
Precursor flares in OJ 287
P. Pihajoki, M. Valtonen, S. Zola +19
We have studied three most recent precursor flares in the light curve of the blazar OJ 287 while invoking the presence of a precessing binary black hole in the system to explain th…
Attractor behaviour in ELKO cosmology
Abhishek Basak, Jitesh R. Bhatt, S. Shankaranarayanan +1
We study the dynamics of ELKO in the context of accelerated phase of our universe. To avoid the fine tuning problem associated with the initial conditions, it is required that the…
Investigation of variability of iron emission lines in Centaurus X-3
Sachindra Naik, Biswajit Paul
We present the results obtained from a study of the variability of iron emission lines in the high mass X-ray binary pulsar Cen X-3 during the eclipse, eclipse-egress and out-of-ec…
Thermodynamic Properties of Strongly Interacting Matter in a Finite Volume using the Polyakov-Nambu-Jona-Lasinio model
Abhijit Bhattacharyya, Paramita Deb, Sanjay K. Ghosh +2
We present the thermodynamic properties of strongly interacting matter in finite volume in the framework of Polyakov loop enhanced NambuJona-lasinio model within mean field appr…
