Roche, Stephan

ICREA Research Professor at Institut Català de Nanociència i Nanotecnologia (ICN2).
Engineering Sciences

Short biography

ICREA Prof. Stephan Roche is working at the Catalan Institute of Nanosciences and Nanotechnology-ICN2 and BIST. He leads the "Theoretical and Computational Nanoscience" group which focuses on physics of Dirac materials (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 and got PhD (1996) at Grenoble University (France); worked in Japan, Spain & Germany; was appointed as assistant Prof. in 2000, CEA Researcher in 2004 and joined ICREA in 2009. He received the Friedrich Wilhelm Bessel prize from the Alexander von Humboldt Foundation (Germany). 

Research interests

S. Roche and his group theoretically explore exotic quantum transport in Dirac Matter including graphene and topological insulators, and 2D materials-based van der Waals heterostructures. Main current interests include (i) quantum interferences and decoherence mechanisms in presence of electron-phonon coupling and spin-orbit interaction, (ii) spin dynamics and spin-torque phenomena in van der Waals heterostructures, (iii) topological effects in Dirac Matter (iv) thermal transport and thermoelectricity in two-dimensional materials (v) quantum devices simulation and (vi) quantum technologies (quantum computing and entanglement in many body physics). Roche´s group has developed unrivalled quantum transport methodologies allowing the study of realistic models of disordered materials up to relevant technology and industrial scales.
