Popis: Halide perovskites display physical properties that are of both practical and fundamental interest. At high pressure, the low-temperature electrical transport in one such compound, CsPbI3, is now shown to be due to Cs-mediated electron-electron interactions resulting in Fermi-liquid-like behaviour.
