Linear redshift parametrization of deceleration parameter in f(R,Lm) gravity
(Elsevier B.V., 2024)In this study, we investigate the linear redshift parametrization of q(z) within the framework of f(R,Lm) gravity, using constraints derived from H(z)/Pantheon samples. We consider a non-linear functional form for f(R,Lm), ... -
Liquid-(Solid plus Liquid) Transitions in a Two-Component System of (CH3)CCl3 + CCl4
(Springer/Plenum Publishers, 2020)Liquid-(solid + liquid) transitions are studied in (CH3)CCl3 + CCl4 by using the Landau phenomelogical model. The Gibbs energy is expanded in terms of the orientational disorder (OD) parameters for the transitions of the ... -
Localization-delocalization transition in the random dimer model
(Amer Physical Soc, 2010)The random-dimer model is probably the most popular model for a one-dimensional disordered system where correlations are responsible for delocalization of the wave functions. This is the primary model used to justify the ... -
Molecular, vibrational and electronic structure of 4-bromo-2-halogenobenzaldehydes: Halogen and solvent effects
(Walter De Gruyter Gmbh, 2017)The halogen and solvent effects on the structure of 4-bromo-2-halogenobenzaldehydes [C7H4BrXO; X = F (BFB), Cl (BCB) or Br (BBB)] were investigated by the density functional theory (DFT) and time-dependent density functional ... -
New traversable wormhole solutions in Einstein Gauss-Bonnet gravity
(World Scientific, 2023)This paper explores the existence of static wormholes in 4-Dimensional Einstein Gauss-Bonnet (4D EGB) gravity. We discuss some possibilities for constructing radial-dependent shape functions via different strategies to ... -
The origins of tetrahedral coordination in molten and glassy ZnCl2 and other group-2B metal dihalides
(Elsevier, 2014)We report the results of first-principles calculations carried out within a relativistic density-functional method, on the molecular trimers of the MX2 compounds (with M = Zn or Cd and X = Cl, Br, or I), showing how a ... -
Periodic and solitary waves of the nonlinear Konno–Oono model: generalized methods
(Springer, 2023)There has been considerable academic interest in the study of nonlinear dynamical models and their exact traveling waves over the past few years. The main aim of the present paper is to consider a nonlinear dynamical model ... -
Quantum boomerang effect: Beyond the standard Anderson model
(American Physical Society, 2021)It was recently shown that wavepackets with a skewed momentum distribution exhibit a boomeranglike dynamics in the Anderson model due to Anderson localization: after an initial ballistic motion, they make a U-turn and ... -
The role of atomistic processes in growth of Cu–Ni metallic/bimetallic nanoparticles
(Elsevier B.V., 2023)Controlling the morphology of non-noble bimetallic nanocrystals can provide an excellent opportunity to improve performance and activity in catalytic reactions. Although several studies have focused on the overall macroscopic ... -
A simple method to determine high-accuracy refractive indices of liquid crystals and the temperature behavior of the related optical parameters via high-resolution birefringence data
(Elsevier, 2014)We report new high-resolution experimental data for the optical birefringence over the temperature range spanning the nematic (N) and smectic A (Sm A) phases of various liquid crystals (LCs) by means of a rotating-analyzer ... -
Static and dynamic structure of monomers, dimers and trimers of HgCl2 from density-functional calculations
(Springer, 2012)We report relativistic density-functional calculations for the equilibrium structures and the vibrational frequencies of the (HgCl2)(n) molecules with n = 1 to 3, as part of a broad exploration of the potential energy ... -
