Electrostatically stabilized surface flat bands in rhombohedral graphite at zero displacement field
Kryštof Kolář, Andrea F. Young, Cyprian Lewandowski
Rhombohedral (ABC-stacked) multilayer graphene hosts interaction-driven phases enabled by surface flat bands at large displacement fields. In thick flakes, however, strong screenin…
Family of High-Chern-Number Orbital Magnets in Twisted Rhombohedral Graphene
Xirui Wang, L. Antonio Benítez, Vo Tien Phong +5
Realizing Chern insulators with Chern numbers greater than one remains a major goal in quantum materials research. Such platforms promise multichannel dissipationless chiral transp…
Is disorder a friend or a foe to melting of Wigner-Mott insulators?
Mohammed Hammam, Cyprian Lewandowski, Vladimir Dobrosavljevic +1
Wigner crystals are extremely fragile, which is shown to result from very strong geometric frustration germane to long-range Coulomb interactions. Physically, this is manifested by…
Superconductivity from dual-surface carriers in rhombohedral graphene
Manish Kumar, Derek Waleffe, Anna Okounkova +7
Intrinsic rhombohedral graphene hosts an unusual low-energy electronic wavefunction, predominantly localized at its outer crystal faces with negligible presence in the bulk. Increa…
Tunable interplay of orbital and spin magnetization in trigonal tellurium
Zhenqi Hua, Chang Niu, Sandeep Joy +8
Orbital effects, despite their fundamental significance and potential to engender novel physical phenomena and enable new applications, have long been underexplored compared to the…
Coulomb Interaction-Stabilized Isolated Narrow Bands with Chern Numbers in Twisted Rhombohedral Trilayer-Bilayer Graphene
Vo Tien Phong, Cyprian Lewandowski
Recently, fractional quantum anomalous Hall effects have been discovered in two-dimensional moiré materials when a topologically nontrivial band with Chern number i…
Single-gate tracking behavior in flat-band multilayer graphene devices
Kryštof Kolář, Dacen Waters, Joshua Folk +2
A central feature of many van der Waals (vdW) materials is the ability to precisely control their charge doping, , and electric displacement field, , using top and bottom gat…
Origin and stability of generalized Wigner crystallinity in triangular moiré systems
Aman Kumar, Cyprian Lewandowski, Hitesh J. Changlani
Generalized Wigner crystals (GWC) on triangular moiré superlattices, formed from stacking two layers of transition metal chalcogenides, have been observed at multiple fractional fi…
Optical Absorption and Emission from Wannier-Stark Spectra of Moiré Superlattices
Vo Tien Phong, Francisco Guinea, Cyprian Lewandowski
Using a formalism based on the non-Abelian Berry connection, we explore quantum geometric signatures of Wannier-Stark spectra in two-dimensional superlattices. The Stark energy can…
