Three-dimensional imaging of integrated-circuit activity using quantum defects in diamond
Marwa Garsi, Rainer Stöhr, Andrej Denisenko +8
The continuous scaling of semiconductor-based technologies to micron and sub-micron regimes has resulted in higher device density and lower power dissipation. Many physical phenome…
Lateral diffusion of phospholipids in artificial cell membranes measured by single shallow NV centers
Farida Shagieva, Andrea Zappe, Daniel Cohen +3
We measure diffusion of organic molecules located a few nanometers from the diamond surface. To study molecular diffusion, we perform local detection of nuclear magnetic resonance,…
Robust and efficient control of spin probes in a complex (biological) environment. Towards sensing of fast temperature fluctuations
Philipp Konzelmann, Torsten Rendler, Ville Bergholm +9
We present an optimized scheme for nanoscale measurements of temperature in a complex environment using the nitrogen-vacancy center in nanodiamonds. To this end we combine a Ramsey…
Quantum light in curved low dimensional hexagonal boron nitride systems
Nathan Chejanovsky, Youngwook Kim, Andrea Zappe +7
Low-dimensional wide bandgap semiconductors open a new playing field in quantum optics using sub-bandgap excitation. In this field, hexagonal boron nitride (h-BN) has been reported…
Molecular quantum spin network controlled by a single qubit
Lukas Schlipf, Thomas Oeckinghaus, Kebiao Xu +10
Scalable quantum technologies will require an unprecedented combination of precision and complexity for designing stable structures of well-controllable quantum systems. It is a ch…
Relaxometry and dephasing imaging of superparamagnetic magnetite nanoparticles using a single qubit
Dominik Schmid-Lorch, Thomas Häberle, Friedemann Reinhard +5
To study the magnetic dynamics of superparamagnetic nanoparticles we use scanning probe relaxometry and dephasing of the nitrogen-vacancy (NV) center in diamond, characterizing the…
Subunit rotation in single FRET-labeled F1-ATPase hold in solution by an anti-Brownian electrokinetic trap
Hendrik Sielaff, Thomas Heitkamp, Andrea Zappe +2
FoF1-ATP synthase catalyzes the synthesis of adenosine triphosphate (ATP). The F1 portion can be stripped from the membrane-embedded Fo portion of the enzyme. F1 acts as an ATP hyd…
Magnetic spin imaging under ambient conditions with sub-cellular resolution
S. Steinert, F. Ziem, L. Hall +6
Measuring spins is the corner stone of a variety of analytical techniques including modern magnetic resonance imaging (MRI). The full potential of spin imaging and sensing across l…
Step size of the rotary proton motor in single FoF1-ATP synthase from a thermoalkaliphilic bacterium by DCO-ALEX FRET
Eva Hammann, Andrea Zappe, Stefanie Keis +5
Thermophilic enzymes can operate at higher temperatures but show reduced activities at room temperature. They are in general more stable during preparation and, accordingly, are co…
