Diffusive Transport in Periodic Potentials: Underdamped Dynamics [PDF]
, 2008 In this paper we present a systematic and rigorous method for calculating the diffusion tensor for a Brownian particle moving in a periodic potential which is valid in arbitrary dimensions and for all values of the dissipation.

Diffusion-induced bistability of driven nanomechanical resonators [PDF]
, 2011 We study nanomechanical resonators with frequency fluctuations due to diffusion of absorbed particles. The diffusion depends on the vibration amplitude through inertial effect.

Nonperturbative estimate of the heavy quark momentum diffusion coefficient [PDF]
, 2015 We estimate the momentum diffusion coefficient of a heavy quark within a pure SU(3) plasma at a temperature of about 1.5Tc. Large-scale Monte Carlo simulations on a series of lattices extending up to 1923×48 permit us to carry out a continuum ...

Surface diffusion coefficients for room acoustics : free-field measures [PDF]
, 2000 A surface diffusion coefficient is needed in room acoustics to enable the quality of diffusing surfaces to be evaluated. It may also facilitate more accurate geometric room acoustic models.

Diffusion Tests for Chloride in Concrete Using Wind Tunnel Test
MATEC Web of Conferences, 2017 Diffusion coefficient of chloride in concrete is a predominant factor in chloride penetration into concrete. Two types of diffusion coefficient models are examined here: mean diffusion coefficient D, time-dependent diffusion coefficient D(t).

Time-varying diffusion characteristics of different gases in coal particles
International Journal of Mining Science and Technology, 2017 Based on the analytical solution of gas diffusion in spherical coal particles with a constant diffusion coefficient, a calculation method of time-varying diffusion coefficient is proposed by constructing objective function.
