Modeling core-hole screening in jellium clusters using density functional theory
Modeling core-hole screening jellium clusters density functional theory
2012/2/28
The screening of a 2p core-hole in Na clusters is investigated using density functional theory applied to an extended jellium model with an all-electron atom in the center. The study is related to rec...
In this work we investigate small clusters of helium atoms using the hyperspherical harmonic basis. We consider systems with A = 2, 3, 4, 5, 6 atoms with an inter-particle potential which does not pre...
Possible realization of the Exciton Bose Liquid phase in a hard-core boson model with ring-only exchange interactions
Possible realization ring-only exchange interactions
2010/11/17
We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a K1
term acts on 1×1 plaquettes and a K2 term acts on 1×2 and 2×1 plaquettes, with a goal of realizing a no...

We study experimentally the interfacial instability between a layer of dilute polymer solution and water flowing in a thin capillary. The use of microfluidic devices allows us to observe and quantify...
