Cosmological singularities in non-canonical models of dark energy
Oem Trivedi, Simran Kaur Saggu, Pankaj S. Joshi
The pursuit of unraveling the true essence of dark energy has become an immensely captivating endeavor in modern cosmology. Alongside the conventional cosmological constant approac…
Optimal Bounds on the Growth of Iterated Sumsets in Abelian Semigroups
Shalom Eliahou, Eshita Mazumdar
We provide optimal upper bounds on the growth of iterated sumsets for finite subsets of abelian semigroups. More precisely, we show that the new upper bounds rec…
Cosmological singularities in gravity
Oem Trivedi, Maxim Khlopov, Jackson Levi Said +1
The pursuit of understanding the mysteries surrounding dark energy has sparked significant interest within the field of cosmology. While conventional approaches, such as the cosmol…
ULDM self-interactions, tidal effects and tunnelling out of satellite galaxies
Bihag Dave, Gaurav Goswami
It is well-known that Dark Matter (DM) inside a satellite galaxy orbiting a host halo experiences a tidal potential. If DM is ultra-light, given its wave-like nature, one expects i…
Joshi--Malafarina--Narayan singularity in weak magnetic field
Mustapha Azreg-Aïnou, Kauntey Acharya, Pankaj S. Joshi
The importance and significance of magnetic fields in the astrophysical scenario is well known. Many domains of astrophysical black hole physics such as polarized shadow image, hig…
Recent advances in cosmological singularities
Oem Trivedi
The discovery of universe's late-time acceleration and dark energy has overseen a great deal of research into cosmological singularities and in this brief review, we discuss all th…
A quantum approach for digital signal processing
Alok Shukla, Prakash Vedula
We propose a novel quantum approach to signal processing, including a quantum algorithm for low-pass and high-pass filtering, based on the sequency-ordered Walsh-Hadamard transform…
Little Rip, Pseudo Rip and bounce cosmology with generalized equation of state in non-standard backgrounds
Oem Trivedi, Alexander V. Timoshkin
The discovery of universe's late-time acceleration and dark energy has overseen a great deal of research into cosmological singularities and particularly future singularities. Perh…
Imaging ultra-compact objects with radiatively inefficient accretion flows
Saurabh, Parth Bambhaniya, Pankaj S. Joshi
Recent Event Horizon Telescope observations of M87* and Sgr A* strongly suggests the presence of supermassive black hole at their respective cores. In this work, we use the semi-an…
An efficient quantum algorithm for preparation of uniform quantum superposition states
Alok Shukla, Prakash Vedula
Quantum state preparation involving a uniform superposition over a non-empty subset of -qubit computational basis states is an important and challenging step in many quantum com…
Quantum computing with subwavelength atomic arrays
Freya Shah, Taylor L. Patti, Oriol Rubies-Bigorda +1
Photon-mediated interactions in subwavelength atomic arrays have numerous applications in quantum science. In this manuscript, we explore the potential of three-level quantum emitt…
Machine Vision Using Cellphone Camera: A Comparison of deep networks for classifying three challenging denominations of Indian Coins
Keyur D. Joshi, Dhruv Shah, Varshil Shah +3
Indian currency coins come in a variety of denominations. Off all the varieties Rs.1, RS.2, and Rs.5 have similar diameters. Majority of the coin styles in market circulation for d…
Estimating related words computationally using language model from the Mahabharata -- an Indian epic
Vrunda Gadesha, Keyur D Joshi, Shefali Naik
'Mahabharata' is the most popular among many Indian pieces of literature referred to in many domains for completely different purposes. This text itself is having various dimension…
Self-interactions of ULDM to the rescue?
Bihag Dave, Gaurav Goswami
One of the most important questions in cosmology is concerning the fundamental nature of dark matter (DM). DM could consist of spinless particles of very small mass i.e. $m \sim 10…
Energy extraction from Janis-Newman-Winicour naked singularity
Vishva Patel, Kauntey Acharya, Parth Bambhaniya +1
In general, energy extraction methods such as the Penrose process and the magnetic Penrose process are thought to be reliant on the existence of an ergoregion. Inside an ergoregion…
A generalization of Bernstein-Vazirani algorithm with multiple secret keys and a probabilistic oracle
Alok Shukla, Prakash Vedula
A probabilistic version of the Bernstein-Vazirani problem (which is a generalization of the original Bernstein-Vazirani problem) and a quantum algorithm to solve it are proposed. T…
