Energy-Efficient Quadruped Locomotion with Compliant Feet
Pramod Pal, Shishir Kolathaya, Ashitava Ghosal
Quadruped robots are often designed with rigid feet to simplify control and maintain stable contact during locomotion. While this approach is straightforward, it limits the ability…
Machine Learning for Multi-messenger Probes of New Physics and Cosmology: A Review and Perspective
Andrea Addazi, Konstantin Belotsky, Vitaly Beylin +18
The multi-messenger exploration of dark matter and physics beyond the Standard Model has emerged as a central direction in modern astro-particle physics, particularly following the…
Optical appearance of regularized compact objects without an exterior photon sphere
Ashok B. Joshi, Vishva Patel, Parth C. Varasani
Recent observations by the Event Horizon Telescope (EHT) indicate that the shadow of the compact object at our Galaxy's center (Sgr A*) closely resembles that of a Schwarzschild bl…
Thermodynamic Phase Transitions and Quantum Entropy Corrections in the Simpson-Visser Regular Black Hole
Vinayak Joshi, Ashok B. Joshi
Regular black holes offer a compelling framework to explore the consequences of resolving the central singularity of standard black holes. Using the Simpson-Visser ``black-bounce"…
Cosmology in the De Donder-Weyl Formulation of Einstein-Cartan Gravity
Aarav Shah, M. Yu. Khlopov, M. Krasnov
We investigate torsion-driven cosmological dynamics within the framework of Einstein-Cartan gravity using the De Donder-Weyl Hamiltonian formalism, where the tetrad and Lorentz con…
Quasinormal Ringing and Unruh-Verlinde Temperature of the Frolov Black Hole
Akshat Pathrikar
In this study, we investigate electromagnetic and Dirac test field perturbations of a charged regular black hole arising from quantum gravity effects, commonly referred to as the F…
Tidal disruption of a neutron star near naked singularity
Ashok B. Joshi, Pankaj S. Joshi, Sudip Bhattacharyya
We investigate the tidal disruption of a neutron star (NS) near a black hole (BH), and for the first time, to the best of our knowledge, near a naked singularity (NaS). For a BH wi…
A Modular, Adaptive, and Scalable Quantum Factoring Algorithm
Alok Shukla, Prakash Vedula
Shor's algorithm for integer factorization offers an exponential speedup over classical methods but remains impractical on Noisy Intermediate Scale Quantum (NISQ) hardware due to t…
Towards Practical Quantum Phase Estimation: A Modular, Scalable, and Adaptive Approach
Alok Shukla, Prakash Vedula
Quantum Phase Estimation (QPE) is a cornerstone algorithm in quantum computing, with applications ranging from integer factorization to quantum chemistry simulations. However, the…
Could Planck Star Remnants be Dark Matter?
Oem Trivedi, Abraham Loeb
We explore the end state of gravitational collapse under quantum gravity effects and propose that Planck Star Remnants (PSR), formed via nonsingular bounces, could serve as viable…
A two-step strategy to identify episodic sources of gravitational waves and high energy neutrinos in starburst galaxies
M. L. Allen, P. L. Biermann, L. I. Caramete +12
Supermassive black hole mergers with spin-flips accelerate energetic particles through their precessing relativistic jets, producing high energy neutrinos and finally gravitational…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
Retrograde Precession of Relativistic Orbits and the Quest for Charged Black Holes
Parth Bambhaniya, Meet J. Vyas, Pankaj S. Joshi +1
The S-stars around the center of the milky way galaxy provide us with detailed information about the nature of the supermassive compact object Sagittarius A* (Sgr A*). In this work…
On Formation of Primordial Naked Singularities
Koushiki, Pankaj S. Joshi, Sudip Bhattacharyya
The density fluctuations in the nearly homogeneous background in the very early universe are argued to be the origin of the cosmic structures we observe in our present universe. Al…
Astrophysical Black holes: An Explanation for the Galaxy Quenching
Jay Verma Trivedi, Pankaj S. Joshi, Gopal-Krishna +1
In light of increasing observational evidence supporting the existence of ultra-compact objects, we adopt the term astrophysical black hole to refer to any object having a huge mas…
Efficient quantum algorithm for weighted partial sums and numerical integration
Alok Shukla, Prakash Vedula
This paper presents a quantum algorithm for efficiently computing partial sums and specific weighted partial sums of quantum state amplitudes. Computation of partial sums has impor…
Rips and regular future scenario with Holographic Dark Energy: A comprehensive look

Interest on the possible future scenarios the universe could have has grew substantially with breakthroughs on late-time acceleration. Holographic dark energy (HDE) presents a very…
Further Arithmetic Properties of Overcubic Partition Triples
Manjil P. Saikia, Abhishek Sarma
In this short note, we prove several new congruences for the overcubic partition triples function, using both elementary techniques and the theory of modular forms. These extend th…
