Electron-phonon-driven three-dimensional metallicity in an insulating cuprate

Fabrizio Carbone, Cédric Weber, Edoardo Baldini

The role of the crystal lattice for the electronic properties of cuprates and other high-temperature superconductors remains controversial despite decades of theoretical and experimental efforts. While the paradigm of strong electronic correlations suggest ...

Longitudinal and transverse modulation of electron wave function with light, and its application to electron microscopy

Fabrizio Carbone, Ivan Madan, Giovanni Maria Vanacore, Enrico Pomarico, Gabriele Berruto

Conventional electron microscopy operates with flat electron wave fronts. Employing attenuative or electrostatic phase plates allows transversally modulating the wave front, enhancing cross-sections of particular scattering channels. Utilization of light f ...
