9. Diamond-based color center for quantum optics and quantum sensing applications

Dr Jacopo Forneris (University of Torino, and INFN - National Institute for Nuclear Physics)

Invited

Color centers in diamond are systems with appealing photo-physical properties for the development of quantum technologies. The ever-growing interest in these systems is motivated by their operation at room temperature, together with an ease of access and manipulation in a solid state system characterized by high transparency and structural stability, with applications as bright and stable...

42. Unambiguous identification of the split-vacancy configuration of the SnV− defect in diamond

Submitted

Point defects in diamond are being intensively investigated for their applications in processing and communication of quantum information, as well as for metrology. So far, the negatively charged nitrogen-vacancy center (NV−) has been the most studied defect [1]. Thanks to its efficient optical spin polarization and spin-state dependent fluorescence, it is being exploited, for example, in the...

38. Hyperfine studies on the structural phase transitions of the naturally layered perovskite Ca2MnO4

Pedro Miguel Da Rocha Rodrigues (IFIMUP, Universidade do Porto (PT))

Submitted

Naturally layered perovskites (NLP) such as the Ruddlesden-Popper (R.P.) phases ($\text{Ca}_{\text{n+1}}\text{Mn}_{\text{n}}\text{O}_{\text{3n+1}}$) have appeared as a fascinating route to achieve nonexpensive room temperature multiferroic materials. In these NLP, specifically in the $\text{Ca}_{\text{3}}\text{Mn}_{\text{2}}\text{O}_{\text{7}}$ compound, distortions of the lattice such...

22. Lattice location of $^{229}$Th in CaF$_2$

Janni Dimitri Moens (KU Leuven (BE))

Submitted

The $^{229}$Th nucleus can be excited to a nuclear isomer state with an extremely low excitation energy of $8.28\pm 0.17$ eV. This excited state is within range of current laser technologies, making it an ideal candidate for optical nuclear clock applications. However, the production of such a nuclear clock is hindered by that same low excitation energy, which is of the order of typical...
