Type V singularities with inhomogeneous equations of state
Oem Trivedi
Interest in cosmological singularities has remarkably grown in recent times, particularly on future singularities with the discovery of late-time acceleration of the universe and d…
A hybrid classical-quantum algorithm for digital image processing
Alok Shukla, Prakash Vedula
A hybrid classical-quantum approach for evaluation of multi-dimensional Walsh-Hadamard transforms and its applications to quantum image processing are proposed. In this approach, m…
Another look on the connections of Hubble tension with the Heisenberg Uncertainty Principle
Oem Trivedi
The Hubble tension is one of the most exciting problems that Cosmology faces today. A lot of possible solutions for it have already been proposed in the last few years, with a lot…
Mechanical overtone frequency combs
Matthijs H. J. de Jong, Adarsh Ganesan, Andrea Cupertino +2
Mechanical frequency combs are poised to bring the applications and utility of optical frequency combs into the mechanical domain. So far, their main challenge has been strict requ…
Lorentz violating inflation and the Swampland
Oem Trivedi
The swampland conjectures from String theory have had very interesting implications for cosmology and particularly for Inflation. It has been shown that the single field inflationa…
Light trajectory and shadow shape in the rotating naked singularity
Vishva Patel, Divya Tahelyani, Ashok B. Joshi +2
In this paper, we investigate the light trajectories and shadow properties in the rotating version of null naked singularity (NNS) spacetime which is derived using the Newman- Jani…
Comparing thin accretion disk properties of naked singularities and black holes
Divya Tahelyani, Ashok B. Joshi, Dipanjan Dey +1
In the present paper, we study the thermal properties of the geometrically thin accretion disks surrounding the null naked singularity (NNS) and the first type of Joshi-Malafarina-…
Horizon-scale tests of gravity theories and fundamental physics from the Event Horizon Telescope image of Sagittarius A
Sunny Vagnozzi, Rittick Roy, Yu-Dai Tsai +12
Horizon-scale images of black holes (BHs) and their shadows have opened an unprecedented window onto tests of gravity and fundamental physics in the strong-field regime. We conside…
Singularity formation in asymptotically safe cosmology with inhomogeneous equation of state
Oem Trivedi, Maxim Khlopov
Interest in cosmological singularities has remarkably grown in recent times, particularly on future singularities with the discovery of late-time acceleration of the universe and d…
Strategic Analysis of Griefing Attack in Lightning Network
Subhra Mazumdar, Prabal Banerjee, Abhinandan Sinha +2
Hashed Timelock Contract (HTLC) in Lightning Network is susceptible to a griefing attack. An attacker can block several channels and stall payments by mounting this attack. A state…
Constraints on the mass and self-coupling of Ultra-Light Scalar Field Dark Matter using observational limits on galactic central mass
Sayan Chakrabarti, Bihag Dave, Koushik Dutta +1
It is well known that Ultra-Light Dark Matter (ULDM), usually scalar fields of mass , can solve some of the outstanding problems of the Cold Dark Matter (…
Non-local slicing approaches for NNLO QCD in MCFM
John M. Campbell, R. Keith Ellis, Satyajit Seth
We present the implementation of several processes at Next-to-Next-to Leading Order (NNLO) accuracy in QCD in the parton-level Monte Carlo program MCFM. The processes treated are $…
Type V singularities in non-standard cosmological backgrounds
Oem Trivedi, Maxim Khlopov
Interest in cosmological singularities has remarkably grown in recent times, particularly on future singularities with the discovery of late-time acceleration of the universe and d…
On finite time singularities in scalar field dark energy models based in the RS-II Braneworld
Oem Trivedi, Maxim Khlopov
The quest of deciphering the true nature of dark energy has proven to be one of the most exciting in recent times in cosmology. Various ideas have been put forward in this regard b…
