Coherence properties of NV-center ensembles in diamond coupled to an electron-spin bath

Reyhaneh Ghassemizadeh, Wolfgang Körner, Daniel F. Urban +1

We investigate nitrogen-vacancy center (NV) ensembles in diamond under the influence of strongly-correlated electron-spin baths. We thoroughly calculate the decoherence properties…

Theoretical limits of magnetic detection of structural surface defects at the nanometer scale

Wolfgang Körner, Daniel F. Urban, Christian Elsässer

We present a theoretical study on the magnetic signals of structural surface defects like cracks or indents combined with rough surfaces or subsurface inclusions of soft ferromagne…

Stability and electronic structure of NV centers at dislocation cores in diamond

Reyhaneh Ghassemizadeh, Wolfgang Körner, Daniel F. Urban +1

We present a density functional theory analysis of the negatively charged nitrogen-vacancy (NV) defect complex located at or close to the core of 30 and 90 partial…

Stability and magnetic properties of grain boundaries in the inverse Heusler phase FeCoGa and in bcc Fe

Daniel F. Urban, Wolfgang Körner, Christian Elsässer

We investigate grain boundaries (GBs) in the cubic inverse Heusler phase FeCoGa by means of first principles calculations based on density functional theory. Besides the energe…

Influence of (N,H)-terminated surfaces on stability, hyperfine structure, and zero-field splitting of NV centers in diamond

Wolfgang Körner, Reyhaneh Ghassemizadeh, Daniel F. Urban +1

We present a density functional theory analysis of the negatively charged nitrogen-vacancy (NV) defect complex in diamond located in the vicinity of (111)- or (100)-oriented su…
