Insulators at Fractional Fillings in Twisted Bilayer Graphene Partially Aligned to Hexagonal Boron Nitride
Dillon Wong, Kevin P. Nuckolls, Myungchul Oh +4
At partial fillings of its flat electronic bands, magic-angle twisted bilayer graphene (MATBG) hosts a rich variety of competing correlated phases that show sample to sample variat…
Quantum textures of the many-body wavefunctions in magic-angle graphene
Kevin P. Nuckolls, Ryan L. Lee, Myungchul Oh +11
Interactions among electrons create novel many-body quantum phases of matter with wavefunctions that often reflect electronic correlation effects, broken symmetries, and novel coll…
Observation of a multitude of correlated states at the surface of bulk 1T-TaSe crystals
Yi Chen, Wei Ruan, Jeffrey D. Cain +5
The interplay between electron-electron interactions and structural ordering can yield exceptionally rich correlated electronic phases. We have used scanning tunneling microscopy t…
Evidence for a spinon Kondo effect in cobalt atoms on single-layer 1T-TaSe
Yi Chen, Wen-Yu He, Wei Ruan +13
Quantum spin liquids (QSLs) are highly entangled, disordered magnetic states that arise in frustrated Mott insulators and host exotic fractional excitations such as spinons and cha…
Spectroscopy of Twisted Bilayer Graphene Correlated Insulators
Dumitru Călugăru, Nicolas Regnault, Myungchul Oh +6
We analytically compute the scanning tunneling microscopy (STM) signatures of integer-filled correlated ground states of the magic angle twisted bilayer graphene (TBG) narrow bands…
Evidence for unconventional superconductivity in twisted bilayer graphene
Myungchul Oh, Kevin P. Nuckolls, Dillon Wong +5
The emergence of superconductivity with doping from correlated insulators in magic-angle twisted bilayer graphene (MATBG) has raised the intriguing possibility that its pairing mec…
