Shadows in conformally related gravity theories

Kunal Pal, Kuntal Pal, Rajibul Shaikh +1

Null geodesics are invariant under a conformal transformation, and thus it might seem natural to assume that the observables corresponding to the shadow of a space-time are also co…

Investigating Numeracy Learning Ability of a Text-to-Text Transfer Model

Kuntal Kumar Pal, Chitta Baral

The transformer-based pre-trained language models have been tremendously successful in most of the conventional NLP tasks. But they often struggle in those tasks where numerical un…

Nielsen complexity of coherent spin state operators

Kunal Pal, Kuntal Pal, Tapobrata Sarkar

We calculate Nielsen's circuit complexity of coherent spin state operators. An expression for the complexity is obtained by using the small angle approximation of the Euler angle p…

Constraining alternatives to the Kerr black hole

Rajibul Shaikh, Kunal Pal, Kuntal Pal +1

The recent observation of the shadow of the supermassive compact object M87 by the Event Horizon Telescope (EHT) collaboration has opened up a new window to probe the strong gr…

Disformal transformations and the motion of a particle in semi-classical gravity

Sandip Chowdhury, Kunal Pal, Kuntal Pal +1

The approach to incorporate quantum effects in gravity by replacing free particle geodesics with Bohmian non-geodesic trajectories has an equivalent description in terms of a confo…
