TÍTULO: New 2D Topological Materials: Silicene, a case study

Resumo:
A brief introduction to non-specialists (the speaker himself being one of them) will be given to the main concepts of Topological Insulators: Quantum Hall effect, Haldane model, Spin Quantum Hall effect, CdTe/HgTe quantum wells, Graphene, and (briefly) Silicene (a cousin of Graphene). The award of the 2016 Physics Nobel prize to Thouless, Haldane, and Kosterlitz highlights the current importance of this subject, which, from the Quantum Hall effect discovery in 1980 to the measurement of the Quantum Spin Hall effect in 2007, has created large new areas of research in Condensed Matter Physics, the most recent being Majorana fermions and Weil semimetals. Time permitting, the speaker will present results for the Kondo effect in Silicene zigzag nanoribbons. (Doughnuts and oranges will be served before the talk).
