Ascendance of Superconductivity in Magic-Angle Graphene Multilayers
Yiran Zhang, Robert Polski, Cyprian Lewandowski +10
Graphene moire superlattices have emerged as a platform hosting and abundance of correlated insulating, topological, and superconducting phases. While the origins of strong correla…
Spectroscopic Signatures of Strong Correlations and Unconventional Superconductivity in Twisted Trilayer Graphene
Hyunjin Kim, Youngjoon Choi, Cyprian Lewandowski +7
Magic-angle twisted trilayer graphene (MATTG) has emerged as a novel moiré material that exhibits both strong electronic correlations and unconventional superconductivity. However,…
Gate-defined wires in twisted bilayer graphene: from electrical detection of inter-valley coherence to internally engineered Majorana modes
Alex Thomson, Ina Sorensen, Stevan Nadj-Perge +1
Twisted bilayer graphene (TBG) realizes a highly tunable, strongly interacting system featuring superconductivity and various correlated insulating states. We establish gate-define…
Interaction-driven Band Flattening and Correlated Phases in Twisted Bilayer Graphene
Youngjoon Choi, Hyunjin Kim, Cyprian Lewandowski +8
Flat electronic bands, characteristic of magic-angle twisted bilayer graphene (TBG), host a wealth of correlated phenomena. Early theoretical considerations suggested that, at the…
Does filling-dependent band renormalization aid pairing in twisted bilayer graphene?
Cyprian Lewandowski, Stevan Nadj-Perge, Debanjan Chowdhury
Magic-angle twisted bilayer graphene exhibits a panoply of many-body phenomena that are intimately tied to the appearance of narrow and well-isolated electronic bands. The microsco…
