    Role of defects in determining the magnetic ground state of ytterbium titanate

    Pyrochlore systems are ideally suited to the exploration of geometrical frustration in three dimensions, and their rich phenomenology encompasses topological order and fractional excitations. Classical spin ic...

    In situ strain tuning of the metal-insulator-transition of Ca2RuO4 in angle-resolved photoemission experiments

    Pressure plays a key role in the study of quantum materials. Its application in angle resolved photoemission (ARPES) studies, however, has so far been limited. Here, we report the evolution of the k-space electro...
