Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Polymer Engineering &Science, EarlyView.We present the Moving Least‐Squares Aided Finite Element Method (MLS‐FEM) as a robust approach to evaluate flow fields in polymer mixers. Using a fixed background mesh that is independent of rotor shape and motion, MLS‐FEM captures distributive and dispersive mixing without the need for mesh regeneration.

N(κ)-paracontact metric manifolds admitting the Fischer-Marsden conjecture
AIMS MathematicsWe characterize $ N(\kappa) $-paracontact metric manifolds (NKPMM) $ M^{2n+1} $ satisfying the Fischer-Marsden conjecture. We demostrate that, if an $ M^{2n+1} $ satisfies the Fischer-Marsden equation, then either $ M^{2n+1} $ with $ \kappa > -1 ...

Coherence, Transport, and Chaos in 1D Bose–Hubbard Model: Disorder vs. Stark Potential
Fortschritte der Physik, EarlyView.Quantum coherence and criticality in finite Bose–Hubbard chains are investigated using exact diagonalization. Thermal fluctuations, Stark potential, and disorder reshape coherence, visibility, and superfluid response. Finite‐size systems show signatures of quantum criticality, with disorder suppressing global superfluidity but preserving local ...

AdS geometry from CFT on a general conformally flat manifold
Nuclear Physics B, 2018 We construct an anti-de-Sitter (AdS) geometry from a conformal field theory (CFT) defined on a general conformally flat manifold via a flow equation associated with the curved manifold, which we refer to as the primary flow equation.
