In this paper, we study a self-dual black hole (BH) in Loop Quantum Gravity (LQG), analyzing both timelike and null geodesics. Using observational data from Mercury's perihelion shift and the orbit of ...

X-ray free-electron lasers (XFELs) of high brightness have opened new opportunities for exploring ultrafast dynamical processes in matter, enabling imaging and movies of single molecules and particles ...

This paper investigates the application of Quantum Generative Adversarial Networks (QGANs) for stock price prediction. Financial markets are inherently complex, marked by high volatility and intricate ...

We investigate the properties of the renormalisation group (RG) flow of two-dimensional sigma models with a generic metric coupling by utilising known results for the Ricci flow. We point out that on ...

This paper proposes a new detector concept that uses the decoupling of superconducting Cooper pairs to detect particles, which has a theoretical energy threshold at the sub-meV level. However, ...

The properties of Milky Way satellite galaxies have important implications for galaxy formation, reionization, and the fundamental physics of dark matter. Ho ...

Cross-chain bridges and oracle DAOs represent some of the most vulnerable components of decentralized systems, with more than $2.8 billion lost due to trust failures, opaque validation behavior, and ...

Adaptive variational algorithms suffer from prohibitively high measurement costs during the generator selection step, since energy gradients must be estimated for a large operator pool. This scaling ...

Abhishek Hegade K R is affiliated with Illinois U., Urbana, and his research focuses on general relativity and quantum cosmology.

The nature of dark matter remains unknown, motivating the study of fuzzy/wave dark matter (FDM/ψDM) and self-interacting dark matter (SIDM) as alternative frameworks to address small-scale ...
