Coulomb screening of superconductivity in magic-angle twisted bilayer graphene
Julien Barrier, Liangtao Peng, Shuigang Xu +7
The origin of superconductivity in magic-angle twisted bilayer graphene has been a subject of intense debate. While some experimental evidence indicated an unconventional pairing m…
Terahertz photocurrent probe of quantum geometry and interactions in magic-angle twisted bilayer graphene
Roshan Krishna Kumar, Geng Li, Riccardo Bertini +24
Moiré materials represent strongly interacting electron systems bridging topological and correlated physics. Despite significant advances, decoding wavefunction properties underlyi…
Infrared Spectroscopy for Diagnosing Superlattice Minibands in Magic-angle Twisted Bilayer Graphene
Geng Li, Roshan Krishna Kumar, Petr Stepanov +11
Twisted bilayer graphene (TBG) represents a highly tunable, strongly correlated electron system owed to its unique flat electronic bands. However, understanding the single-particle…
One-dimensional proximity superconductivity in the quantum Hall regime
Julien Barrier, Minsoo Kim, Roshan Krishna Kumar +16
Extensive efforts have been undertaken to combine superconductivity and the quantum Hall effect so that Cooper-pair transport between superconducting electrodes in Josephson juncti…
