Effective Transport Properties of Lattices [PDF]
SIAM Journal on Applied Mathematics, 2017 Summary: The method of multiple scales is used to calculate the effective macroscopic transport properties of a random walk on a periodic lattice with arbitrary, spatially dependent transition rates. In contrast to the standard multiple-scales approach for continuous media, the fast scale here is discrete, and only the slow scale is continuous.

Transport of melt, pressure and heat through a magma mush
Frontiers in Earth Science, 2023 Prior to intrusion, magma migrates through the crustal plumbing system that likely contains layers or columns of crystal mush. To better understand the behavior of the crustal magmatic system during magmatic unrest, it is important to examine the process

Certain Aspects of Quantum Transport in Zigzag Graphene Nanoribbons
Frontiers in Physics, 2022 We have investigated the Fano factor and shot noise theoretically in the confined region of the potential well of zigzag graphene nanoribbon (ZGNR). We have found that the Fano factor is approximately 1, corresponding to the minimum conductivity (σ) for ...
