Dirac vs. Majorana Dark Matter Imprints on Neutron Star Observables
M. Bhuyan, Jeet Amrit Pattnaik, S. K. Patra +1
The fundamental character of a fermionic dark matter, whether it is a Dirac or Majorana particle remains a key unresolved issue whose answer would profoundly affect dark-sector phe…
Core or Halo? Two-Fluid Analysis of Dark Matter-Admixed Quarkyonic Stars in the Multi-Messenger Era
Jeet Amrit Pattnaik, D. Dey, M. Bhuyan +2
For the first time, we explore dark matter (DM) admixed quarkyonic stars (DAQSs) within a two-fluid formalism, where the normal/visible sector is modeled by a quarkyonic equation o…
-mode oscillation of neutron star in a new relativistic hybrid model
D. Dey, Jeet Amrit Pattnaik, R. N. Panda +1
We investigate how the pulsation frequencies of axial gravitational-wave modes (-modes) in a non-rotating neutron star depend on its composition, particularly when including qua…
Anomalous Behavior of Giant Monopole Resonance Energy with Nuclear Matter Incompressibility in the framework of Relativistic Mean Field Formalism and Coherent Density Fluctuation Model
Jeet Amrit Pattnaik, R. N. Panda, M. Bhuyan +1
The finite nucleus incompressibility is evaluated using the coherent density fluctuation model with the extended relativistic mean field density. The relativistic energy dens…
Exploring the giant monopole resonance in superheavy nuclei: A theoretical perspective
S. Kumar, Jeet Amrit Pattnaik, S. K. Singh +3
Within the relativistic mean field framework, in an extended Thomas-Fermi approximation, we calculate the binding energy and charge distribution radius for the latest superheavy nu…
Superheavy Nuclei and the Changing Face of Nuclear Magicity
Jeet Amrit Pattnaik, Santosh Kumar, S. K. Singh +3
Using a relativistic mean field formalism, we analyzed the magic number sequence for finite nuclei in the superheavy valley. The result for the IOPB-I parameter set is compared wit…
