Neutral kaons in random media [PDF]
The generalized dynamics describing the propagation of neutral kaons in randomly fluctuating media is derived and analyzed. It takes into account possible matter-induced effects leading to loss of phase coherence and dissipation. The study of selected neutral kaon observables indicates that these non-standard effects are amenable to a direct ...

Bosonic excitations in random media [PDF]
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.

3D MORPHOLOGICAL MODELLING OF A RANDOM FIBROUS NETWORK
In the framework of the Silent Wall ANR project, the CMM and the US2B are associated in order to characterize and to model fibrous media studying 3D images acquired with an X-Ray tomograph used by the US2B.

Correlations and screening of topological charges in Gaussian random fields [PDF]
Two-point topological charge correlation functions of several types of geometric singularity in Gaussian random fields are calculated explicitly, using a general scheme: zeros of n-dimensional random vectors, signed by the sign of their Jacobian ...

Discrete-Time Semi-Markov Random Evolutions in Asymptotic Reduced Random Media with Applications
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.

Phase singularities in isotropic random waves [PDF]
The singularities of complex scalar waves are their zeros; these are dislocation lines in space, or points in the plane. For waves in space, and waves in the plane (propagating in two dimensions, or sections of waves propagating in three), we calculate ...

Random walks in disordered lattice, CTRW, memory and dipole transport [PDF]
Application of CTRW (continuous time random walks) to dipole hopping transport is reviewed. Conditions of applicability of basic kinetic equations to spin systems are indicated.

Random walk on the range of random walk [PDF]
We study the random walk X on the range of a simple random walk on ℤ d in dimensions d≥4. When d≥5 we establish quenched and annealed scaling limits for the process X, which show that the intersections of the original simple random walk path are ...

Optomechanics of random and nonlinear media
We theoretically investigate the effects of randomness and nonlinearity on optical forces. Disorder enhances the light induced mechanical effects and ultra-fast nonlinear polarization may give a negative contribution to the optical pressure.
