Workshop on Recent Advances in Condensed Matter Physics and Optics, held 14 November, 2013, at The Hong Kong University of Science and Technology.
Abstract: It has become possible in recent years to fabricate and manipulate two-dimensional (2D) nanomaterials in the laboratory that are as thin as one to few atomic layers. A well-known example is graphene, where the Dirac-Weyl Hamiltonian for massless fermions describes the low-energy quasiparticles. Intriguing physics has been found in these few-layer systems, and phenomena originally associated with particle physics can now be observed in condensed matter systems. In this talk, the speaker will focus on recent computational studies of a few representative systems, including the neutrino-like oscillation and anisotropic transport in twisted bilayer graphene that also exhibits a rare fractal-like 'butterfly' energy spectrum under external magnetic field. In addition, the speaker will also discuss the possibility of growing 2D structures of other group-IV elements on graphene. It is expected that many of the unique electronic properties of graphene can also be realized in this new 2D system.
