Characterization of Autofluorescence in Optical Fibers for NV-based Sensing Applications
Stefan Johansson, Alexander Bukschat, Dennis Lönard +3
Optical fibers are crucial for guiding light in various sensing applications. Especially for quantum sensors such as the nitrogen-vacancy (NV) center in diamond, they enable light…
Limits of absolute vector magnetometry with NV centers in diamond
Dennis Lönard, Isabel Cardoso Barbosa, Stefan Johansson +2
The nitrogen-vacancy (NV) center in diamond has become a widely used platform for quantum sensing. The four NV axes in mono-crystalline diamond specifically allow for vector magnet…
Miniaturized magnetic-field sensor based on nitrogen-vacancy centers
Stefan Johansson, Dennis Lönard, Isabel Cardoso Barbosa +3
The nitrogen-vacancy (NV) center in diamond is a prime candidate for quantum sensing technologies. Here, we present a fully integrated and mechanically robust fiber-based endoscopi…
Objective comparison of methods to decode anomalous diffusion
Gorka Muñoz-Gil, Giovanni Volpe, Miguel Angel Garcia-March +31
Deviations from Brownian motion leading to anomalous diffusion are found in transport dynamics from quantum physics to life sciences. The characterization of anomalous diffusion fr…
Probing the fluctuating magnetic field of Fe-triazole spin-crossover thin-layers with nitrogen-vacancy centers in diamond
Isabel Cardoso Barbosa, Tim Hochdörffer, Juliusz A. Wolny +5
Fe spin-crossover (SCO) complexes are materials that change their magnetic properties upon temperature variation, exhibiting a thermal hysteresis. Particularly inte…
