Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds
Advanced Materials, EarlyView.We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling
Advanced Optical Materials, EarlyView.Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

Digitale Medien versus Tafel und Kreide — Online- und Hybridlehre in der Theoretischen Physik
Lessons Learned, 2022 Die Wissensvermittlung in der Theoretischen Physik ist nicht an Demonstrationsexperimente und Versuchsaufbauten vor Ort gebunden. Dies bietet eine erhöhte Flexibilität beim Wechsel zwischen Präsenz- und Online-Lehre.

Advanced Optical Materials, EarlyView.Understanding exciton fine structure is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization‐sensitive photon‐echo spectroscopy in a magnetic field resolves exciton fine‐structure splittings hidden by inhomogeneous broadening, enabling direct determination of the bright‐dark ...

Sohn-Rethel und die Häutungen der modernen Physik
Recherches Germaniques, 2020 Sohn-Rethel always insisted on the necessity of solving the conflict between the use of dialectic in the social sciences and the use of a logic of exclusion in the natural sciences. This article reconstructs the way in which modern physics since 1900 has

Advanced Science, EarlyView.This work reports on epitaxially grown Hf0.52Zr0.48O2 ferroelectric memristors with high stability (high durability exceeding 108 cycles and a retention time exceeding 104 s for 16 states) and ultra‐low operating energy consumption (∼121 fJ). A memristor array‐based reservoir computing system is constructed and applied for the first time in the field ...
