The dominating mode of two competing massive modes of quadratic gravity
Avijit Chowdhury, Semin Xavier, S. Shankaranarayanan
Over the last two decades, motivations for modified gravity have emerged from both theoretical and observational levels. and Chern-Simons gravity have received more attentio…
Ab-initio study of the effect of bromide mixing into RbPbI on the structural, electronic and optical properties
Anupriya Nyayban, Subhasis Panda, Avijit Chowdhury
The ultra-high efficiency and cost-effective photovoltaics based on halide preovskites have brought a revolution to ongoing photovoltaic research, surpassing the expectations of th…
Naked singularity in 4D Einstein-Gauss-Bonnet novel gravity: Echoes and (in)-stability
Avijit Chowdhury, Saraswati Devi, Sayan Chakrabarti
We study the stability of an asymptotically flat, static, spherically symmetric naked singularity spacetime in the novel four dimensional Einstein-Gauss-Bonnet (EGB) gravity. The f…
The effect of B-site alloying on the electronic and opto-electronic properties of RbPbI3: A DFT study
Anupriya Nyayban, Subhasis Panda, Avijit Chowdhury
Divalent cations mixed lead halide perovskites with enhanced performances, high stabilities, and reduced toxicity are requisite to make persistent progress in perovskite solar cell…
On the effect of scalar fields on Hawking radiation and quasinormal modes of black holes
Avijit Chowdhury
The present thesis attempts to study the effect of scalar fields on Hawking radiation and quasinormal modes of black holes. We selected a static, spherically symmetric electrically…
Echoes from a singularity
Avijit Chowdhury, Narayan Banerjee
Though the cosmic censorship conjecture states that spacetime singularities must be hidden from an asymptotic observer by an event horizon, naked singularities can form as the end…
