A search for correlation-induced adiabatic paths between distinct topological insulators
Johannes S. Hofmann, Fakher F. Assaad, Raquel Queiroz +1
Correlations in topological states of matter provide a rich phenomenology, including a reduction in the topological classification of the interacting system compared to its non-int…
Fractional Chern Insulator States in Twisted Bilayer Graphene: An Analytical Approach
Patrick J. Ledwith, Grigory Tarnopolsky, Eslam Khalaf +1
Recent experiments on bilayer graphene twisted near the magic angle have observed spontaneous integer quantum Hall states in the presence of an aligned hexagonal boron nitride (hBN…
Ground State and Hidden Symmetry of Magic Angle Graphene at Even Integer Filling
Nick Bultinck, Eslam Khalaf, Shang Liu +3
In magic angle twisted bilayer graphene, electron-electron interactions play a central role resulting in correlated insulating states at certain integer fillings. Identifying the n…
Spin-polarized Correlated Insulator and Superconductor in Twisted Double Bilayer Graphene
Xiaomeng Liu, Zeyu Hao, Eslam Khalaf +5
Ferromagnetism and superconductivity typically compete with each other since the internal magnetic field generated in a magnet suppresses the formation of spin-singlet Cooper pairs…
Theory of correlated insulating behaviour and spin-triplet superconductivity in twisted double bilayer graphene
Jong Yeon Lee, Eslam Khalaf, Shang Liu +4
Two monolayers of graphene twisted by a small `magic' angle exhibit nearly flat bands leading to correlated electronic states and superconductivity, whose precise nature including…
Magic Angle Hierarchy in Twisted Graphene Multilayers
Eslam Khalaf, Alex J. Kruchkov, Grigory Tarnopolsky +1
When two monolayers of graphene are stacked with a small relative twist angle, the resulting band structure exhibits a remarkably flat pair of bands at a sequence of 'magic angles'…
