In collaboration with our partners, we have contributed to the following scientific advancements:
1) Discovery of superconductivity at the interface between two insulators, Science 317, 1196 (2007).
This result was a runner-up for the Breakthrough of the Year 2007 awarded by Science magazine.
2) Discovery of a superconductor-insulator quantum phase transition driven by electrostatic fields at oxide interfaces, Nature 456, 624 (2008).
News and views: Clear leap for superconductors.
This result was awarded the 2009 Swiss Physical Society Prize for Applied Physics.
3) Discovery of a large spin-orbit interaction at oxide interfaces, Physical Review Letters 104, 126803 (2010).
This result has stimulated several theoretical studies and could be the key for understanding the coexistence of magnetism and superconductivity at LaAlO3/SrTiO3 interfaces.
4) Experimental demonstration of two-dimensional electronic states originating from quantum confinement at a complex oxide interface, Physical Review Letters 105, 236802 (2010).
5) Discovery that a sudden excitation of the lattice vibrations in a crystal can trigger a change of the magnetic and conducting properties of an atomically-thin layer that lies on its surface, Physical Review Letters 108, 136801 (2012), Nature Materials 14, 883 (2015).
