Collective excitation(plasmon) modes of an electron
gas in a multilayer system (superlattice) have been studied
in great detail in recent years. One important aspect
of this Fermion system is that the dispersion relation of
the plasma frequency shows transitional behavior between
two- and three- dimensional character. Inelastic light
scattering experiment...
Water temperature influenced interactions between redside
shiners and juvenile steelhead trout (≥1+) in the field and the
laboratory. Distribution of the two species within various habitats
was determined in three streams with different water temperature
regimes. The range of habitats occupied by trout in allopatry at
cool temperatures and at...
