Local spectroscopy of anyons bound to charge traps
Jeong Min Park, Cristian Voinea, Yen-Chen Tsui +7
Fractional quantum Hall states host anyons, emergent quasiparticles with fractional charge and nontrivial exchange statistics. Controlling, trapping, and braiding anyons are centra…
Layer-polarized Transport via Gate-defined 1D and 0D PN Junctions in Double Bilayer Graphene
Wei Ren, Xi Zhang, Shiyu Guo +6
We fabricate twisted double bilayer graphene devices with zero twist angle and a set of local top and bottom gates aligned perpendicularly to each other. A 1D PN junction can be el…
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…
Strong interactions and isospin symmetry breaking in a supermoiré lattice
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +10
In multilayer moiré heterostructures, the interference of multiple twist angles ubiquitously leads to tunable ultra-long-wavelength patterns known as supermoiré lattices. However,…
Tunable interplay between light and heavy electrons in twisted trilayer graphene
Andrew T. Pierce, Yonglong Xie, Jeong Min Park +5
In strongly interacting systems with multiple energy bands, the interplay between electrons with different effective masses and the enlarged Hilbert space drives intricate correlat…
Fractional Chern insulators in magic-angle twisted bilayer graphene
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +12
Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall states that may provide a new avenue toward manipulating non-abelian excitations. Early theoreti…
Large Pauli Limit Violation and Reentrant Superconductivity in Magic-Angle Twisted Trilayer Graphene
Yuan Cao, Jeong Min Park, Kenji Watanabe +2
Moiré quantum matter has emerged as a novel materials platform where correlated and topological phases can be explored with unprecedented control. Among them, magic-angle systems c…
Unconventional sequence of correlated Chern insulators in magic-angle twisted bilayer graphene
Andrew T. Pierce, Yonglong Xie, Jeong Min Park +11
The interplay between strong electron-electron interactions and band topology can lead to novel electronic states that spontaneously break symmetries. The discovery of flat bands i…
Entropic evidence for a Pomeranchuk effect in magic angle graphene
Asaf Rozen, Jeong Min Park, Uri Zondiner +9
In the 1950's, Pomeranchuk predicted that, counterintuitively, liquid 3He may solidify upon heating, due to a high excess spin entropy in the solid phase. Here, using both local an…
Flavour Hund's Coupling, Correlated Chern Gaps, and Diffusivity in Moiré Flat Bands
Jeong Min Park, Yuan Cao, Kenji Watanabe +2
Interaction-driven spontaneous symmetry breaking lies at the heart of many quantum phases of matter. In moiré systems, broken spin/valley 'flavour' symmetry in flat bands underlies…
Nematicity and Competing Orders in Superconducting Magic-Angle Graphene
Yuan Cao, Daniel Rodan-Legrain, Jeong Min Park +6
Strongly interacting electrons in solid-state systems often display tendency towards multiple broken symmetries in the ground state. The complex interplay between different order p…
