Superradiant energy extraction from rotating hairy Horndeski black holes
Sohan Kumar Jha, Mohsen Khodadi, Anisur Rahaman +1
Adopting the manifest of low-frequency and low mass for the scalar perturbation, we perform a semi-classical analysis of the superradiance phenomenon for a rotating hairy Horndeski…

On the indistinguishability of Chiral QED with parameter-free Faddeevian anomaly and QED under a chiral constraint
Anisur Rahaman
We carry out an investigation imposing a chiral constraint in the phase space of vector and axial-vector Schwinger model. We find that resulting model is identical to gauge non-inv…

Study of Einstein-bumblebee gravity with Kerr-Sen-like solution in the presence of a dispersive medium
Sohan Kumar Jha, Sahazada Aziz, Anisur Rahaman
A Kerr-Sen-like black hole solution appears in the Einstein-bumblebee theory of gravity. The solution contains contains a Lorentz violating parameter in an explicit manner. We stud…
