Multi-Knob Switchable Chiral Superconductivity Quartet in Rhombohedral Graphene
Zhenqi Hua, Shenyong Ye, Phatthanon Pattanakanvijit +17
Chiral superconductors break orbital time-reversal symmetry and may host topological quasiparticles with non-Abelian statistics. In rhombohedral graphene, superconductivity develop…
Valley Valves at Domain Walls in Symmetry-Broken Rhombohedral Graphene
Vo Tien Phong, Francisco Lobo, Elsa Prada +3
Rhombohedral multilayer graphene polarized by a moderate perpendicular displacement field hosts a time-reversal-symmetry-breaking valley-and-spin-polarized metallic phase that may…
Family of High-Chern-Number Orbital Magnets in Twisted Rhombohedral Graphene
Xirui Wang, L. Antonio BenÃtez, 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…
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 …
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…
Squeezing Quantum States in Three-Dimensional Twisted Crystals
Vo Tien Phong, Kason Kunkelmann, Christophe De Beule +4
A fundamental idea in wave mechanics is that propagation in a periodic medium can be described by Bloch waves whose conserved crystal momenta define their transformations when disp…
