Friedel Oscillations In A Fermi Liquid, G. E. Simion, G. F. Giuliani
Friedel Oscillations In A Fermi Liquid, G. E. Simion, G. F. Giuliani
Department of Physics and Astronomy Faculty Publications
The problem of the Friedel oscillations in two- and three-dimensional electron Fermi liquids is examined by means of the many-body local fields theory as aided by the most recent results of accurate numerical studies based on the quantum Monte Carlo method. Within linear response, an exact answer is obtained for the amplitude of the electron density distortion due to both short- and long-ranged impurity potentials. It is discussed how a measurement of the local environment of an impurity embedded in an otherwise homogeneous electron liquid can be used to characterize the systems as a Fermi liquid as well as to …

Tectonic changes that produced a deep Tasmanian Gateway between Australia and Antarctica are widely invoked as the major mechanism for Antarctic cryosphere growth and Antarctic Circumpolar Current (ACC) development during the Eocene/Oligocene (E/O) transition (∼34–33 Ma). Ocean Drilling Program (ODP) Leg 189 recovered near-continuous marine sedimentary records across the E/O transition interval at four sites around Tasmania. These records are largely barren of calcareous microfossils but contain a rich record of siliceous- and organic-walled marine microfossils. In this study we integrate micropaleontological, sedimentological, geochemical, and paleomagnetic data from Site 1172 (East Tasman Plateau) to identify four distinct phases (A–D) in …
Eocene Circulation Of The Southern Ocean: Was Antarctica Kept Warm By Subtropical Waters?, Matthew Huber, Henk Brinkhuis, Catherine E. Stickley, Kristofer Döös, Appy Sluijs
Eocene Circulation Of The Southern Ocean: Was Antarctica Kept Warm By Subtropical Waters?, Matthew Huber, Henk Brinkhuis, Catherine E. Stickley, Kristofer Döös, Appy Sluijs
Department of Earth, Atmospheric, and Planetary Sciences Faculty Publications
Near the Eocene's close (∼34 million years ago), the climate system underwent one of the largest shifts in Earth's history: Antarctic terrestrial ice sheets suddenly grew and ocean productivity patterns changed. Previous studies conjectured that poleward penetration of warm, subtropical currents, the East Australian Current (EAC) in particular, caused Eocene Antarctic warmth. Late Eocene opening of an ocean gateway between Australia and Antarctica was conjectured to have disrupted the EAC, cooled Antarctica, and allowed ice sheets to develop. Here we reconstruct Eocene paleoceanographic circulation in the Tasmanian region, using (1) biogeographical distributions of phytoplankton, including data from recently drilled Ocean …
