    Ultrafast evolution and transient phases of a prototype out-of-equilibrium Mott–Hubbard material

    The study of photoexcited strongly correlated materials is attracting growing interest since their rich phase diagram often translates into an equally rich out-of-equilibrium behaviour. With femtosecond optica...

    Tuning a Schottky barrier in a photoexcited topological insulator with transient Dirac cone electron-hole asymmetry

    The advent of Dirac materials has made it possible to realize two-dimensional gases of relativistic fermions with unprecedented transport properties in condensed matter. Their photoconductive control with ultr...

    Time resolved ultrafast ARPES for the study of topological insulators: The case of Bi2Te3

    We discuss the application of time-resolved ultrafast angle resolved photoelectron spectroscopy to the study of photoexcited topological insulators. Measurements performed on the prototype material Bi2Te3 clearly...

    Time Resolved Photoemission of an Insulator-Metal Transition

    Time resolved photoemission is employed to visualize directly an ultrafast insulator to metal transition and the excitation of a coherent phonon mode in the Mott insulator 1T-TaS2.

    High-Resolution Photoemission in Low Dimensional Conductors

    This chapter describes how strongly correlated quasi one-dimensional conductors are investigated by Angle Resolved Photoelectron Spectroscopy (ARPES). Low dimensional Peierls conductors deviate from the usual ...

    Electronic and magnetic properties of ruthenocuprates

    We report on X-ray photoemission of core levels, valence band studies using angle-integrated photoemission, and magnetization measurements of ruthenocuprate and SrRuO3 polycrystalline samples. The data indicate t...
