Quantum effects on the Rayleigh-Taylor instability of stratified fluid/plasma through porous media

Quantum effect on Rayleigh-Taylor instability of stratified plasma layer through a porous medium are investigated. The linear growth rate is obtained analytically and is analyzed. In the presence of quantum effect, both the porosity of porous medium and the medium permeability has different influence on the coup point (k(coup)*) for stability, but they do not have influence on the critical point (k(c)*) for stability. The quantum effect plays the principal role of the complete stability case for the system considered. (C) 2009 Elsevier B.V. All rights reserved.
