Mid-Term Report Summary - DM (Dirac Materials)

Discoveries of superfluid phases in 3He, high Tc superconductors, graphene and topological insulators have brought into focus materials where quasiparticles are described by same Dirac equation that governs behavior of relativistic particles. This class of materials, called Dirac materials, exhibits unusual universal features seen in numerous realizations: Klein tunneling, chiral symmetries and impurity resonances Goal of this project is to explore these similarities and discuss the unique role of symmetries that protect the Dirac spectrum. We investigated the symmetries of Dirac materials, quantum imaging, and means to control their properties. We find that the universal response of DM to local defects will produce donat bands that can control properties of DM. We propose to use modern tools to design artificial Dirac Materials. For example we show how one can design Bosonic Dirac materials that host bosonic Dirac excitations, something that would not be possible in particle physics.
