Engineering Sciences

ICREA Prof. Stephan Roche is working at the Catalan Institute of Nanosciences and Nanotechnology-ICN2. He leads the "Theoretical & Computational Nanoscience" group which focuses on physics of Topological Quantum Matter (graphene & topological insulators,...) and 2D materials-based van der Waals heterostructures. He pioneered the development of linear scaling quantum transport approaches enabling simulations of billion atoms-scale disordered models (  He studied Theoretical Physics at ENS, got PhD (1996) at Grenoble University (France); worked in Japan, Spain & Germany; appointed assistant Prof. in 2000, CEA Researcher in 2004 and ICREA in 2009. Award: Friedrich Wilhelm Bessel prize from the Alexander von Humboldt Foundation (Germany). 

Research interests

S. Roche explores quantum transport in Topological Quantum Matter including graphene & topological insulators, and 2D materials-based van der Waals heterostructures and amorphous structures (amorphous boron-nitride & graphene). Topics (i) topological physics & entanglement (ii) Artificial Intelligence applied to Condensed Matter (ii) spin transport phenomena (iii) quantum decoherence mechanisms (iv) thermal transport at nanoscale (v) quantum devices simulation (vi) use of Artificial Intelligence techniques to boost materials design in advanced electronics, quantum technologies and energy harvesting technologies
