Digital-magnetic heterostructures ~DMH’s!, II-VI quantum wells with ‘‘planes’’ of Mn, exhibit strongly spin-dependent physics. We investigate the magnetic-field (B) dependence of exchange-induced energy splittings and spin-flip scattering in DMH’s. We find that Mn clustering is relevant to explain the magnitude and the concentration dependence of recently observed splittings. Our calculated ele...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
A characteristic feature of hyperbolic systems of balance laws is the existence of non-trivial equilibrium solutions, where the effects of convective fluxes and source terms cancel each other. Recently a number of so-called well-balanced schemes were developed which satisfy a discrete analogue of this balance and are therefore able to maintain an equilibrium state. In most cases, applications t...
