An analytical representation for the simplest of the diffusions
E. J. Nunes-Pereira
An analytical representation for the spatial and temporal dynamics of the simplest of the diffusions -- Bronwian diffusion in an homogeneous slab geometry, with radial symmetry --…
Signatures of Lévy flights with annealed disorder
Q. Baudouin, R. Pierrat, A. Eloy +4
We present theoretical and experimental results of Lévy flights of light originating from a random walk of photons in a hot atomic vapor. In contrast to systems with quenched disor…
Controllable transport mean free path of light in xerogel matrixes embedded with polystyrene spheres
Boris P. J. Bret, Nuno J. G. Couto, Mariana Amaro +2
Xerogel matrices, made by sol-gel techniques, are embedded with polystyrene spheres to promote multiple scattering of light. Varying the concentration of the spheres inside the mat…
Radiation trapping in 1D using the Markov chain formalism: A computational physics project
A. R. Alves-Pereira, E. J. Nunes-Pereira, J. M. G. Martinho +1
A computational model study for complete frequency redistribution linear incoherent two-level atomic radiation trapping in optically dense media using the multiple scattering repre…
Advantages of the multiple scattering representation approach to radiation trapping
E. J. Nunes-Pereira, A. R. Alves-Pereira, J. M. G. Martinho +1
A simple stochastic formulation of the multiple scattering representation solution of the classical linear incoherent trapping problem is presented for a broad audience. A clear co…
Photonic superdiffusive motion in resonance line radiation trapping - partial frequency redistribution effects
A. R. Alves-Pereira, E. J. Nunes-Pereira, J. M. G. Martinho +1
The relation between the jump length probability distribution function and the spectral line profile in resonance atomic radiation trapping is considered for Partial Frequency Redi…
