The behavior of partially coherent twisted space-time beams in atmospheric turbulence
Frontiers in Physics, 2023 We study how atmospheric turbulence affects twisted space-time beams, which are non-stationary random optical fields whose space and time dimensions are coupled with a stochastic twist.

Acoustic Wave Correlation Tomography of Time-Varying Disordered Structures
Archives of Acoustics, 2018 An original model based on first principles is constructed for the temporal correlation of acoustic waves propagating in random scattering media. The model describes the dynamics of wave fields in a previously unexplored, moderately strong (mesoscopic ...

Discrete-Time Semi-Markov Random Evolutions in Asymptotic Reduced Random Media with Applications
Mathematics, 2020 This paper deals with discrete-time semi-Markov random evolutions (DTSMRE) in reduced random media. The reduction can be done for ergodic and non ergodic media.

Effective waves for random three-dimensional particulate materials
New Journal of Physics, 2021 How do you take a reliable measurement of a material whose microstructure is random? When using wave scattering, the answer is often to take an ensemble average (average over time or space).

Bosonic excitations in random media [PDF]
Physical Review B, 2003 We consider classical normal modes and non-interacting bosonic excitations in disordered systems. We emphasise generic aspects of such problems and parallels with disordered, non-interacting systems of fermions, and discuss in particular the relevance for bosonic excitations of symmetry classes known in the fermionic context.

Networks and Heterogeneous Media, 2012 We consider a model for the propagation of a driven interface through a random field of obstacles. The evolutionequation, commonly referred to as the Quenched Edwards-Wilkinson model, is a semilinear parabolic equationwith a constant driving term and ...

Advanced Electronic Materials, 2023 Random granular media can exhibit characteristics that are often related to ordered media. In the present work, this feature is observed in the polarized Second Harmonic Generation (SHG) response from reduced iron‐doped lithium niobate (LN:Fe) powders ...

Networks and Heterogeneous Media, 2006 Under consideration is the finnite-size scaling of effective thermoelastic properties of random microstructures from a Statistical Volume Element(SVE) to a Representative Volume Element (RVE), without invoking any periodic structure assumptions, but only

A central limit theorem for pulled fronts in a random medium
Networks and Heterogeneous Media, 2011 We consider solutions to a nonlinear reaction diffusion equation when the reaction term varies randomly with respect to the spatial coordinate. The nonlinearity is the KPP type nonlinearity.
