Polarization discontinuities in two-dimensional honeycomb lattices — •Marco Gibertini, Giovanni Pizzi, and Nicola Marzari — Theory and Simulation of Materials, École Polytechnique Fédérale de Lausanne, Switzerland

The unprecedented and fascinating phenomena taking place at oxide interfaces such as LaAlO3/SrTiO3 have recently triggered the search for their two-dimensional analogues. In this respect, honeycomb lattices seem to offer a rich playground, both for their versatility and the fundamental experimental developments that ensued from the discovery of graphene. In this talk we would like to emphasize, with the help of atomistic first-principles simulations, how to achieve polar discontinuities across interfaces between honeycomb lattices, elucidating the key physical processes that occur and their possible practical applications.
