Identifying the loss mechanisms of niobium film cavities enables an accurate determination of applications for future accelerator projects and points to research topics required to mitigate their limi...
Impurity-assisted Andreev reflection at a spin-active half-metal-superconductor interface
Impurity-assisted Andreev reflection spin-active half-metal-superconductor interface
2012/2/27
The Andreev reflection amplitude at a clean interface between a half-metallic ferromagnet (H) and a superconductor (S) for which the half metal's magnetization has a gradient perpendicular to the inte...
New structural model for GeO2/Ge interface: A first-principles study
New structural model for GeO2/Ge interface first-principles study
2010/11/24
First-principles modeling of a GeO2/Ge(001) interface reveals that sixfold GeO2, which is derived from cristobalite and is different from rutile, dramatically reduces the lattice mismatch at the inter...
Bosonic enhancement of spontaneous emission near an interface
Bosonic enhancement spontaneous emission
2010/11/24
We show how the spontaneous emission rate of an excited two-level atom placed in a trapped Bose-Einstein condensate of ground-state atoms is enhanced by bosonic stimulation. This stimulation depends o...
Enhanced stability of hydrogen atoms at the graphene/graphane interface of nanoribbons
Enhanced stability of hydrogen atoms graphene/graphane interface of nanoribbons
2010/11/24
The thermal stability of graphene/graphane nanoribbons (GGNRs) is investigated using density functional theory. It is found that the energy barriers for the diffusion of hydrogen atoms on the zigzag a...
