Diffusion at constant speed in a model phase space
S. Anantha Ramakrishna, N. Kumar
We reconsider the problem of diffusion of particles at constant speed and present a generalization of the Telegrapher process to higher dimensional stochastic media (), where…
Super-reflection of light from a random amplifying medium with disorder in the complex refractive index : Statistics of fluctuations
S. Anantha Ramakrishna, E. Krishna Das, G. V. Vijayagovindan +1
The probability distribution of the reflection coefficient for light reflected from a one-dimensional random amplifying medium with {\it cross-correlated} spatial disorder in the r…
Imaginary Potential as a Counter of Delay Time for Wave Reflection from a 1D Random Potential
S. Anantha Ramakrishna, N. Kumar
We show that the delay time distribution for wave reflection from a one-dimensional random potential is related directly to that of the reflection coefficient, derived with an arbi…
Diffusion of particles moving with constant speed
S. Anantha Ramakrishna, N. Kumar
The propagation of light in a scattering medium is described as the motion of a special kind of a Brownian particle on which the fluctuating forces act only perpendicular to its ve…
Photon transport in thin disordered slabs
Venkatesh Gopal, S. Anantha Ramakrishna, A. K. Sood +1
We examine using Monte Carlo simulations, photon transport in optically `thin' slabs whose thickness L is only a few times the transport mean free path , with particles of d…
