Far-infrared excitations in a quantum antidot at finite magnetic fields
A. Emperador, M. Pi, M. Barranco +2
We have investigated the far-infrared dipole modes of a quantum antidot submitted to a perpendicularly applied magnetic field B. The ground state of the antidot is described within…

Pinning of quantized vortices in helium drop by dopant atoms and molecules
Franco Dalfovo, Ricardo Mayol, Marti Pi +1
Using a density functional method, we investigate the properties of liquid 4He droplets doped with atoms (Ne and Xe) and molecules (SF_6 and HCN). We consider the case of droplets…
