  • In heavily hole-doped cuprates, superconductivity does not die by simply dissolving into a uniform metal due to the lack of pairing, but rather survives by shattering into nanoscale superconducting puddles.

  • Current-inducing switching of magnetization is crucial for future magnetic data processing technologies, but switching it with speed and energy efficiency remains challenging. Using femtosecond optical pulses, instead of conventional charge currents, is found to make spintronics not only ultrafast but also counterintuitive.

  • Above-bandgap, nanosecond laser pulses enable the localized in situ writing of spin defects in prefabricated nanophotonic cavities. The approach preserves defect and cavity mode properties, key requirements towards cavity–emitter coupling in quantum networks.
