We give Swampland constraints on the three dimensional Landscape of Anti-de Sitter higher spin gravity in the Chern-Simons formulation with connection valued in various split real forms of Lie algebras. We derive the finiteness conjecture by computing the upper bound on the rank of possible gauge groups then we refine it using the AdS distance conjecture. We discuss the implications of this...

In this paper, we obtain a solution of a static spherically symmetric charged black hole inspired by noncommutative geometry in the context of the regularized 4D-Einstein–Gauss–Bonnet theory in AdS space. The derived metric recovers the standard solutions’ limits. It tends to the commutative case solution found in [P. G. S. Fernandes, Phys. Lett. B 805, 135468 (2020)] at large distance r+θ→∞...

Entanglement entropy can be computed directly by describing the density matrix of the associated system. For gravitational systems such as black holes, the radiation entropy has a geometrical construction given by extremal surfaces. However, due to the quantum characteristics of black holes, this surface can be generalized to quantum extremal surfaces. We outline the derivation of...

Testing the Swampland conjectures in the context of string theory on Calabi-Yau threefolds has led to interesting results,both mathematically and physically. We generalize results of fibration structure of Calabi-Yau fourfold with finite volume in infinite distances in the moduli space. By applying these results to compactifications of M-theory on K3xK3 we relate weak coupling and strong...

This work is a theoretical study of a proposed novel system whose purpose is to convert solar radiation to electrical energy. The study proposed an electron chamber with trapped electrons inside it. The trapped electrons were then excited by photons of specific frequency. The excited electrons were allowed to escape the chamber across a circular boundary to an evacuated coil-shaped path. The...

The Zinc ferrite (ZnFe2O4) has significantly attracted many researchers due to their chemical and thermal stability [1] and their narrow band gap [2]. In this present research we successfully studied the influence of Graphene (Gra) doping on the physical properties of zinc ferrite thin films. The undoped and Gra-doped ZnFe2O4 nanofilms were grown onto glass substrates using spray pyrolysis...

Cold-modified Alfven waves of multi-ion species propagating perpendicular to an ambient magnetic field have been investigated. We derive the linear dispersion relation for any number of species. In addition to the conduction current density, we consider the displacement current density. The derived dispersion relation suggests a magnetized plasma mode to propagate at the long-wavelength for...

Ensuring compliance with maximum residue limits (MRL) for pesticide residues in fresh produce is crucial for food safety. Traditional detection methods such as chromatography and mass spectrometry, while accurate, are often time-consuming, expensive, and require complex sample preparations. This study aimed to evaluate the effectiveness of combining Raman spectroscopy with deep learning...

Quantum communication methods are highly sensitive to variations in protocol parameters, which can affect their effectiveness. This study explores the performance of quantum communication protocols using online quantum computing platforms such as Quirk, Qiskit-IBM-Q, Rigetti Forest, and D-Wave. Despite the promising advancements over classical teleportation, many protocols fall short of their...

Space weather, defined as the variable conditions in space driven by the sun, significantly impacts the performance of both terrestrial and space-based technologies. To mitigate these adverse effects, it is essential to develop accurate storm-time space weather models. Since the sun is the primary driver of these models, solar indices like SSN and F10.7 are crucial for creating these models....

The experimental data from various hadronic and heavy-ion collisions have been studied to investigate nuclear matter under extreme temperature and pressure. Under such conditions, the nuclear matter undergoes different phase transitions from the hadronic matter to the quark-gluon plasma (QGP) matter. Also, there are several experimental indicators that allow studying different regions of the...
