We study the possibility of leptogenesis within the Alternative Left Right Model (ALRM). ALRM is a variant of the Left Right Symmetric Model. Unlike the usual Left Right Symmetric Model, it avoids the flavour changing neutral current. Type-I seesaw generates the majorana mass of the heavy RH neutrino ($\nu_R$), which gives the lepton number violating decay. We find that even for a large value...
In this work, we have studied the used of a thin film-based metal-semiconductor junction to improve the optical absorption, scattering and field intensities of the electromagnetic spectrum in the ultra-violate (UV) region. Nanoparticles (Nps) of copper (Cu), silver (Ag) and gold (Au) with size 14nm are individually incorporated on 5nm thick CdS thin film. The finite difference time domain...
We propose a hybrid scotogenic inverse seesaw framework in which the Majorana mass term is generated at the one-loop level through the inclusion of a singlet fermion. This singlet Majorana fermion also serves as a viable thermal relic dark matter candidate due to its limited interactions with other fields. To construct the model, we adopt an
$A_4$ flavour symmetry in a modular framework,...
A minimal and predictive Majorana neutrino mass matrix texture is proposed. The texture involves four parameters that reveal unique correlations and predict the three neutrino mass eigenvalues, while strictly ruling out the inverted hierarchy. Furthermore, it imposes constraints on the three CP-violating phases. Based on these predictions, we estimate both the effective Majorana neutrino mass...
Secure long-distance communication has become a fundamental requirement in modern information systems, particularly in satellite-based networks where the exchange of sensitive data across vast distances is often exposed to eavesdropping, signal degradation, and transmission errors. Classical communication systems, though widely deployed, face limitations in ensuring unconditional security due...
A theoretical analysis is done to explore the dynamics of nonlinear gravito-electrostatic wave in the molecular clouds. It contains warm lighter electrons, ions and massive positively and negatively charged dust grains. The effects of multi-fluidic viscous drag forces, the gradient forces, naturalistic equilibrium inhomogeneities and nonlinear convective dynamics are also considered. A couple...
Assuming that neutrinos are Majorana particles, we have realized two-zero textures using the $\Gamma_{3}$ modular group. The $\Gamma_{3}$ modular group is a finite modular group isomorphic to the $A_{4}$ group. By assigning the matter fields of the model to irreducible representations of $A_{4}$ and choosing appropriate modular weights, we successfully construct two-zero textures of the...
Kaniadakis Holographic Dark Energy extends the standard holographic dark energy (HDE) model by integrating Kaniadakis entropy, a generalization of the classical Bekenstien-Hawking entropy. Kaniadakis entropy incorporates relativistic statistical mechanics into standard HDE model and is characterized by a deformation parameter K. This study aims to construct a new form of f(R) gravity theory by...
The ubiquitous development of multiple charged layers and their characteristics has been widely investigated in recent years under varied experimental conditions in hollow cathode discharges due to their wide variety of applications [1], [2]. However, no controlled plasma source could be developed during these earlier studies to investigate the underlying cause of formations of complex charged...
Abstract: The last few decades have been revolutionary for semiconductor processing and applications due to their extraordinary optical and electronic properties. In this paper, ZnO and PbO nanoparticles are prepared by chemical bath deposition technique. The structural morphologies of the prepared samples are verified with the help of XRD analysis and HRTEM technique. XRD analysis shows the...
Abstract: Tunability of the Ne ́el temperatures (TN) in case of antiferromagnetic (AFM) materials has significanct importance in exchange bias studies, magnetic and spintronic device applications etc. Interestingly, AFM transition metal oxide thin films demonstrate TN dependance on film thickness and stoichiometry. This article reports the estimation of TN for AFM nickel oxide (NiO) ultrathin...
