Landau Level Phases of Bilayer Graphene

Title: Landau Level Phases of Bilayer Graphene

Summary/Abstract

In addition to quantum computing, harnessing the quantum properties of electrons has historically led to advancements in classical computing as well. For example, in spintronics, giant magnetoresistance was essential for high-density data storage in magnetic hard disk drives. For these quantum degrees of freedom to be accessible, their energy scale must be smaller than that of the host material's band structure. One means to achieve this is through Landau quantization in two-dimensional materials. I will discuss this in the setting of bilayer graphene, which in addition to spin also hosts valley (momentum) and orbital degrees of freedom, and outline how to control the quantum degrees of freedom experimentally.

Brett Green earned his B.S. in Physics and in Mathematics from Montana State University in 2014 and his Ph.D. in Physics from Penn State University in 2022. His research so far can generally be characterized as either phase transitions in condensed matter or quantum information, and he is also interested in the classical physics of everyday systems and real and complex analysis.
