Quantum Effects on Rayleigh-Taylor Instability of a Plasma-Vacuum

The hydrodynamic instability of unmagnetized quantum plasma layer supported by magnetized vacuum layer is investigated. The plasma is considered as incompressible, inviscid and has exponentially varying density. The relation between square normalized growth rate and square normalized wave number is obtained and analyzed. The results are shown that, the interface is more stability in the presence of quantum effect beside the magnetic field effect.
