Quantum Materials

Invited Talk

Chirality is omnipresent in nature, bridging magnetic and molecular spin phenomena. At the core of this connection lies the chiral-induced spin selectivity (CISS) effect, describing the highly efficient generation of spin polarized currents in chiral molecules. Despite extensive experimental evidence, the underlying mechanisms of CISS remain debated. Here, we explore how chirality is directly...

Contributed Talk

Nitrogen Vacancy (NV) centers in diamond have emerged as versatile quantum sensors, enabling nanoscale detection of magnetic and electric fields, temperature shifts, strain and chemical environments under ambient conditions. The unique spin properties of NV centers combined with the exceptional properties of diamond provide a powerful platform for investigating physical, chemical, and...

Biophysics

Contributed Talk

Nitrogen-vacancy (NV) centers in diamond are promising quantum sensors for nuclear magnetic resonance (NMR) on micro- and nanoscale sample volumes. At the Bucher Group, we are developing this technology to probe microscopic and complex biological systems. A key challenge is sensitivity: Small samples contain fewer nuclear spins and therefore generate weak NMR signals. In ensemble NV sensing,...

Contributed Talk

The phenomenon of the chiral-induced spin selectivity (CISS) effect refers to the spin-polarization of electrons in the presence of chiral molecules or structures. Their potential for high polarization efficiencies makes hybrid chiral molecule / magnet devices promising for efficient and sustainable spintronic devices. Despite various experimental reports on different facets of the CISS...

12. Effects of high-temperature annealing on SiV ensembles in CVD-grown diamond

Quantum Optics

Contributed Talk

Monocrystalline diamonds (MCD) embedded with color centers have emerged as promising candidates for applications in quantum optics, namely sensing. Specifically, negatively-charged silicon vacancy centers (SiV) stand out as ideal due to their narrow zero phonon line (ZPL) at 738 nm, coupled with a high Debye-Waller factor of up to 70 %. However, their application remains hindered by the...
