Harnessing the Diamond-Air Interface as an Efficient Photon Antenna for Solid-State Emitters
Paul Weinbrenner, Aina Lopez Benet, İdil Gözel +1
Extracting photons from defect centers is challenging due to the high refractive index of typical substrates. For nitrogen-vacancy centers in diamond, reaching saturation count rat…

ChiSCAT: unsupervised learning of recurrent cellular micro-motion patterns from a chaotic speckle pattern
Andrii Trelin, Sophie Kussauer, Paul Weinbrenner +4
There is considerable evidence that action potentials are accompanied by "intrinsic optical signals", such as a nanometer-scale motion of the cell membrane. Here we present ChiSCAT…
