A 2020 Vision for Programmable Quantum Materials

Abstract:

Novel quantum phases with controllable properties are essential for new electronic and photonic functionalities. Quantum materials offer particularly appealing opportunities for the implementation of on-demand quantum phases. In this talk I will overview recent efforts to discover, characterize and deploy quantum materials controllable by light, gating, and nano-mechanical manipulation, effectively programming their properties. I will focus on several new experiments: i) ultra-fast control of exciton-polaritons and plasmon-polaritons in van der Waals semiconductors and ii) edge state conduction in twisted multi-layers of graphene. I will also discuss our recent advances with multi-messenger nano-imaging: a scanning probe approach for correlating in time and space images produced by diverse contrast mechanisms and carrying complementary massages about the studied phenomena [Nature Materials (in press 2020)].
