Spectroscopic Observations of SN 2012fr: A Luminous Normal Type Ia Supernova with Early High Velocity Features and Late Velocity Plateau
M. J. Childress, R. A. Scalzo, S. A. Sim +55
We present 65 optical spectra of the Type Ia supernova SN 2012fr, of which 33 were obtained before maximum light. At early times SN 2012fr shows clear evidence of a high-velocity f…
Direct Experimental Evidence for the Hybridization of Organic Molecular Orbitals with Substrate States at Interfaces: PTCDA on Silver
J. Ziroff, F. Forster, A. Scholl +2
We demonstrate the application of orbital k-space tomography for the analysis of the bonding occurring at metal-organic interfaces. Using angle-resolved photoelectron spectroscopy…
A flat band at the chemical potential of a Fe1.03Te0.94S0.06 superconductor observed by angle-resolved photoemission spectroscopy
P. Starowicz, H. Schwab, J. Goraus +6
The electronic structure of superconducting Fe1.03Te0.94S0.06 has been studied by angle resolved photoemission spectroscopy (ARPES). Experimental band topography is compared to the…
Defining Photometric Peculiar Type Ia Supernovae
S. Gonzalez-Gaitan, E. Y. Hsiao, G. Pignata +9
We present a new photometric identification technique for SN 1991bg-like type Ia supernovae (SNe Ia), i.e. objects with light-curve characteristics such as later primary maxima and…
Dielectric screening of the Kohn anomaly of graphene on hexagonal boron nitride
F. Forster, A. Molina-Sanchez, S. Engels +5
Kohn anomalies in three-dimensional metallic crystals are dips in the phonon dispersion that are caused by abrupt changes in the screening of the ion-cores by the surrounding elect…
Electric-dipole-induced spin resonance in a lateral double quantum dot incorporating two single domain nanomagnets
F. Forster, M. Mühlbacher, D. Schuh +2
On-chip magnets can be used to implement relatively large local magnetic field gradients in na- noelectronic circuits. Such field gradients provide possibilities for all-electrical…
