Interaction driven charge transfer transitions in closely spaced graphene double layers
Kenneth A. Lin, Unmesh Ghorai, Kenji Watanabe +3
Charge transfer between two conductors is conventionally viewed as a single-particle process governed by electrostatics and band alignment. Using tunneling spectroscopy, we show th…
Resonant Far-Infrared Spectroscopy of Flat-Band Fermions in Magic Angle Graphene
Ayelet J. Uzan-Narovlansky, Ipsita Das, Juan F. Mendez Valderrama +10
Moiré engineering in twisted two-dimensional (2D) materials radically alters low-energy bands, interactions and topological quantum states. Despite extensive studies, optical spect…
Lifshitz transitions and isospin polarization in twist-decoupled monolayer-bilayer graphene
Alex Boschi, Leonardo Sabattini, Sergey Slizovskiy +10
Bernal-stacked bilayer graphene (BLG) hosts correlated electronic phases tied to low-energy Lifshitz transitions at saddle points in its valence band. To access this regime, ultral…
Anomalous metal and superconducting phases in rhombohedral graphene
Anna Okounkova, Abigail Sohm, Tobias Faehndrich +7
Two-dimensional superconductivity is now well established in graphene-based systems, with many such realizations showing evidence for unconventional pairing. Yet in several of the…
Quantum oscillation spectroscopy of Fermi-surface topologies in tetralayer graphene
Abhijit Halder, Harsh Varshney, Snehamoyee Hazra +7
Quantum oscillations offer a direct probe of Fermi-surface topology and electronic degeneracy, yet disentangling both simultaneously across the Lifshitz transitions of multiband sy…
Van Hove singularity-driven giant Nernst signal in twisted double bilayer graphene
Ujjal Roy, Monosij Roy, Unmesh Ghorai +8
Twisted graphene layers host van Hove singularities (vHSs), peaks in the electronic density of states, thought to drive exotic phases in moiré materials, but their effect on therma…
