    Abstract: Essential to a microscopic understanding of strongly correlated materials is a clear picture of the relationship between their myriad quantum ground states. However, in phenomena ranging from unconventional magnetism to high temperature superconductivity, this picture is often obscured by the presence of broken symmetries hidden from view of existing experimental techniques. This may include hidden structural symmetries or tensor order parameters representing complex spatial arrangements of multipolar electric and magnetic moments.

    Abstract: Graphene, a two-dimensional single atomic layer of carbon, has stimulated substantial interest because it is a rich model system for scientific exploration and a promising candidate for future electronics. I will discuss my studies on graphene-based transistors, which lead to the realization of new physical phenomena that is relevant for fundamental science and new device applications. The first part of my talk will focus on electron transport measurements of devices comprised of graphene bilayers.
