Daniel joined the group in 2024 as a postdoctoral researcher. His work studies correlations, topology, and disorder in quantum materials, with a focus on moiré heterostructures and collective response.
Congratulations to Ilia Komissarov, the inaugural Julian Schwinger Fellow. The fellowship supports his studies of quantum geometry in strongly correlated states of matter. See his work on the quantum-geometric origin of capacitance in insulators.
Harshitra joined the group in 2023 as a graduate student. Her research uses quantum field theory and low-energy models to study two-dimensional materials, Fermi-surface instabilities, and entanglement.
Raquel received an NSF CAREER Award for her project on the interplay of crystalline topology and quantum geometry in electronic materials.
Anna joined the group as an undergraduate researcher in 2022 and worked on topological materials. She is now a PhD candidate in Princeton's Program in Applied and Computational Mathematics.
In this recorded Rice University talk, Raquel discusses the stability of chiral Landau levels and what it implies for flat bands in twisted heterostructures.
Raquel co-organized the Aspen Center for Physics program Quantum Matter Through the Lens of Moiré Materials with Philip Kim, Eslam Khalaf, and Jed Pixley. The June 16–July 7, 2024 workshop brought theory and experiment together around correlated phases, topology, and new moiré platforms.
Sebastian joined the group as an undergraduate researcher in 2023. His work contributed to studies of frustrated hopping in Pd5AlI2 and electronic bound states in the continuum. He is now at Amazon.
Tunable Two-Dimensional Materials: Moiré and Beyond
Coordinators: Erez Berg, Eslam Khalaf, Jed Pixley, Raquel Queiroz, and Andrea Young; Scientific Advisors: Liang Fu and Jie Shan
This program will focus on the rapidly developing field of two-dimensional van der Waals materials, which offer unprecedented tunability over the band structure and have now become one of the most exciting venues to observe exotic correlated and topological phenomena. The program will bring together experts from theory and experiment to discuss open questions and challenges in existing van der Waals materials…
We worked with Ady Stern to show how symmetry determines the number of parameters that must be tuned to flatten a Dirac band. Read the paper in Physical Review X.
Peter joined the group in 2022 as a graduate student. His work studies how disorder, topology, and symmetry control delocalization, Landau levels, and ring states.
New demonstrations of superconductivity in multilayer stacks of graphene continue to emerge, even as researchers struggle to explain how it all works.
