An Interplay Between Fractional Calculus and Holographic Dark Energy
Ayush Bidlan
This dissertation aims to put forth a systematic construction of a fractional-calculus extension of holographic dark energy (HDE). We show that linking late-time cosmic acceleratio…
Causal Structure of Spacetime Singularities and Their Observable Signatures
Bina Patel, Jahnvi Mistry, Ayush Bidlan +1
We analyze the causal structure of horizonless compact objects via the light-cone geometry and conformal compactification of the Joshi-Malafarina-Narayan (JMN-1) and Janis-Newman-W…
Gravitational Collapse and Singularity Formation in Brans-Dicke Gravity
Ayush Bidlan, Dipanjan Dey, Parth Bambhaniya
We investigate gravitational collapse driven solely by a self-interacting Brans--Dicke (BD) scalar field in the absence of ordinary matter. In this framework, the spacetime dynamic…
Future Rip Scenarios in Fractional Holographic Dark Energy
Ayush Bidlan, Paulo Moniz, Oem Trivedi
In this paper, we investigate the occurrence of late-time cosmological singularities, namely, the rip scenarios within the framework of interacting Fractional Holographic Dark Ener…
Reconstructing FHDE with Scalar and Gauge Fields
Ayush Bidlan, Paulo Moniz, Oem Trivedi
We revisit the Fractional Holographic Dark Energy (FHDE) model to reconstruct it by means of dynamic candidates such as () Quintessence, () K-essence, () Dilaton, (…
Non-Local Classical Field Theory with Fractional Operators on Space
Abhi Savaliya, Ayush Bidlan
We present a theoretical framework on non-local classical field theory using fractional integrodifferential operators. Due to the lack of easily manageable symmetries in traditiona…
