Generalized torsion for hyperbolic --manifold groups with arbitrary large rank

Tetsuya Ito, Kimihiko Motegi, Masakazu Teragaito

Let be a group and a non-trivial element in . If some non-empty finite product of conjugates of equals to the trivial element, then is called a generalized torsi…

The 2015 super-resolution microscopy roadmap

Stefan Hell, Steffen Sahl, Mark Bates +24

Far-field optical microscopy using focused light is an important tool in a number of scientific disciplines including chemical, (bio)physical and biomedical research, particularly…

Nanometer resolution imaging and tracking of fluorescent molecules with minimal photon fluxes

Francisco Balzarotti, Yvan Eilers, Klaus C. Gwosch +5

We introduce MINFLUX, a concept for localizing photon emitters in space. By probing the emitter with a local intensity minimum of excitation light, MINFLUX minimizes the fluorescen…

Nanoparticle-assisted STED nanoscopy with gold nanospheres

Nicolai T. Urban, Matthew R. Foreman, Stefan W. Hell +1

We demonstrate stimulated emission depletion (STED) microscopy with 20 nm gold nanospheres coated by fluorescent silica. Compared with previous demonstrations of STED with a hybrid…

Superresolution optical magnetic imaging and spectroscopy using individual electronic spins in diamond

Jean-Christophe Jaskula, Erik Bauch, Silvia Arroyo-Camejo +4

Nitrogen vacancy (NV) color centers in diamond are a leading modality for both superresolution optical imaging and nanoscale magnetic field sensing. In this work, we solve the rema…

Achromatic light patterning and improved image reconstruction for parallelized RESOLFT nanoscopy

Andriy Chmyrov, Marcel Leutenegger, Tim Grotjohann +7

Fluorescence microscopy is rapidly turning into nanoscopy. Among the various nanoscopy methods, the STED/RESOLFT super-resolution family has recently been expanded to image even la…
