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…
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…
Obstruction and Interference in Low Energy Models for Twisted Bilayer Graphene
Vo Tien Phong, E. J. Mele
The electronic bands of twisted bilayer graphene (TBLG) with a large-period moiré superlattice fracture to form narrow Bloch minibands that are spectrally isolated by forbidden ene…
Optically-Controlled Orbitronics on a Triangular Lattice
Vo Tien Phong, Zachariah Addison, Seongjin Ahn +3
The propagation of electrons in an orbital multiplet dispersing on a lattice can support anomalous transport phenomena deriving from an orbitally-induced Berry curvature. In striki…
