My research interests center around understanding the underlying mechanisms of many-body phases of matter that are observed in strongly correlated electron systems. The goal of my research is to realize and engineer distinctly interesting and highly applicable electronic behavior in materials using simple and universal guiding principles that we can uncover by studying the inventive and often elegant methods of Mother Nature.

Evidence for Unconventional Superconductivity in Twisted Bilayer Graphene

Our newest paper, published in the journal Nature, describes a number of classic spectroscopic signatures we've observed that demonstrate that superconductivity in magic-angle twisted bilayer graphene is unconventional and is quantitatively inconsistent with a BCS origin.

Strongly Correlated Chern Insulators in MATBG

Here's a video seminar I gave recently at the Princeton Quantum Initiative, discussing our observations of correlation-driven, gate-tunable topological insulators in magic-angle twisted bilayer graphene. Click here to read the full paper.

Cascade of Isospin Symmetry-Breaking Transitions in MATBG

Below is a poster I presented at the ICFO-MIT Schools on the Frontiers of Light "Emergent Phenomena in Moire Materials" Symposium in July of 2020 (http://frontiers.icfo.eu/2020/07/04/kevin-nuckolls/), which details our most recent findings in magic-angle twisted bilayer graphene.
