Magnetically induced electronic ferroelectricity in half-doped manganites
Gianluca Giovannetti, Sanjeev Kumar, Jeroen van den Brink +1
Using a joint approach of density functional theory and model calculations, we demonstrate that a prototypical charge ordered half-doped manganite, LaCaMnO is m…
Quantum limit of the triplet proximity effect in half-metal - superconductor junctions
B. Béri, J. N. Kupferschmidt, C. W. J. Beenakker +1
We apply the scattering matrix approach to the triplet proximity effect in superconductor-half metal structures. We find that for junctions that do not mix different orbital modes,…
Large grains in disks around young stars: ATCA observations of WW Cha, RU Lup, and CS Cha
Dave Lommen, Sarah Maddison, Chris Wright +3
Grains in disks around young stars grow from interstellar submicron sizes to planetesimals over the course of several Myr. Thermal emission of large grains or pebbles can be best o…
Lack of PAH emission toward low-mass embedded young stellar objects
V. C. Geers, E. F. van Dishoeck, K. M. Pontoppidan +4
PAHs have been detected toward molecular clouds and some young stars with disks, but have not yet been associated with embedded young stars. We present a sensitive mid-IR spectrosc…
New CO detections of lensed submillimeter galaxies in A2218: Probing molecular gas in the LIRG regime at high redshift
K. K. Knudsen, R. Neri, J. -P. Kneib +1
Context: Submillimeter galaxies (SMGs) are distant, dusty galaxies undergoing star formation at prodigious rates. Recently there has been major progress in understanding the nature…
The host galaxies of Compact Steep Spectrum and Gigahertz-Peaked Spectrum radio sources
J. Holt
I will review some of the developments in studies of the host galaxy properties of Compact Steep Spectrum (CSS) and GigaHertz-Peaked Spectrum (GPS) radio sources. In contrast to pr…
