Small-world disordered lattices: spectral gaps and diffusive transport

MIN Rosa, M Ruzzene - New Journal of Physics, 2022 - iopscience.iop.org
We investigate the dynamic behavior of lattices with disorder introduced through non-local
network connections. Inspired by the Watts–Strogatz small-world model, we employ a single …

Porous Germanium (PGe) is a very promising material for spectroscopy and detection
applications in the mid-IR wavelength range, due to its particular physicochemical …

Spin Chaos Dynamics in Classical Random Dipolar Interactions

M Momeni - International Journal of Bifurcation and Chaos, 2023 - World Scientific
The stochastic nature of magnetization dynamics of dipole–dipole interactions described by
the Landau–Lifshitz–Gilbert equation without considering the Gilbert damping parameter is …

[PDF][PDF] Dynamics of 'small-world'network phononic lattices: Spectral gaps and diffusive transport

MIN Rosa, M Ruzzene - arXiv preprint arXiv:2203.10381, 2022 - researchgate.net
We investigate a family of elastic lattices with disorder introduced through non-local network
connections. Inspired by the Watts-Strogatz” small-world” model, a single parameter …

Investigating the phase space dynamics of conservative dynamical systems by the Lagrangian descriptors method

S Zimper - 2023 - open.uct.ac.za
In this work, we numerically investigate the dynamics of conservative dynamical systems
using the method of Lagrangian descriptors (LDs), which has been extensively used to …
