Accuracy of the diffusion equation with extrapolated-boundary condition for transmittance of light through a turbid medium
J. C. J. Paasschens, M. J. M. de Jong, C. W. J. Beenakker
The linear intensity profile of multiply scattered light in a slab geometry extrapolates to zero at a certain distance beyond the boundary. The diffusion equation with this "extrap…
Berry phase and adiabaticity of a spin diffusing in a non-uniform magnetic field
S. A. van Langen, H. P. A. Knops, J. C. J. Paasschens +1
An electron spin moving adiabatically in a strong, spatially non-uniform magnetic field accumulates a geometric phase or Berry phase, which might be observable as a conductance osc…
Reflection of light from a disordered medium backed by a phase-conjugating mirror
J. C. J. Paasschens, M. J. M. de Jong, P. W. Brouwer +1
This is a theoretical study of the interplay of optical phase-conjugation and multiple scattering. We calculate the intensity of light reflected by a phase-conjugating mirror when…
Brightness of a phase-conjugating mirror behind a random medium
J. C. J. Paasschens, P. W. Brouwer, C. W. J. Beenakker
A random-matrix theory is presented for the reflection of light by a disordered medium backed by a phase-conjugating mirror. Two regimes are distinguished, depending on the relativ…
Localization in a Disordered Multi-Mode Waveguide with Absorption or Amplification
T. Sh. Misirpashaev, J. C. J. Paasschens, C. W. J. Beenakker
An analytical and numerical study is presented of transmission of radiation through a multi-mode waveguide containing a random medium with a complex dielectric constant $ε= ε'+iε''…
Localization of Light: Dual Symmetry between Absorption and Amplification
J. C. J. Paasschens, T. Sh. Misirpashaev, C. W. J. Beenakker
We study the propagation of radiation through a disordered waveguide with a complex dielectric constant , and show that dual systems, which differ only in the sign of the imagin…
