    Current organic proton detectors have poor detection sensitivities due to low light yields and limited radiation toleration. Here the authors report a perovskite nanocrystal-based transmissive thin scintillator that can detect seven protons per second, enabled by radiative emission from biexcitons.

    Unlike electron spins, nuclear spins in van der Waals materials remain a largely untapped quantum resource. Here we report the fast coherent control of nuclear spins and strong electron-mediated nuclear–nuclear spin coupling in hexagonal boron nitride.

    Strong light–matter coupling in quantum cavities provides a pathway to break fundamental materials symmetries, like time-reversal symmetry in chiral cavities. This Comment discusses the potential to realize non-equilibrium states of matter that have so far been only accessible in ultrafast and ultrastrong laser-driven materials.

    Cavity polaritons have been extensively studied in inorganic materials. An organic polariton condensate is now demonstrated to occur in the strongly interacting regime, at room temperature, in a cavity containing an organic polymer.

    The generation and manipulation of single photons is important for quantum information and metrology. Highly bright and stable single-photon sources are now identified in silicon carbide, a wide-bandgap semiconductor widely used for photonic and electronic devices.
