Quantum transport across normal-superlattice-normal graphene junctions: Fabry-Pérot interference, Hofstadter butterfly, and supersnake states
Che-Pin Hsu, Alina Mreńca-Kolasińska, Aitor Garcia-Ruiz +4
Electrostatic modulation of graphene provides a tunable route to engineering miniband structures. We perform quantum transport simulations on a gate-defined graphene superlattice j…
Efficient Magnetic Spin-Filtering and Persistent Spin-Currents in Lifshitz-Transitioned Altermagnets: A Route to Open-Orbit Spintronics
Wun-Hao Kang, Yu-Ting Hsiao, Jozef Genzor +3
Altermagnets offer a unique venue for spin transport due to their vanishing net magnetization and momentum-dependent spin splitting. We demonstrate that a homotopic Lifshitz transi…
Scalable tight-binding model for strained graphene
Ming-Hao Liu, Christophe De Beule, Alina Mreńca-Kolasińska +4
We generalize the scalable tight-binding model for graphene, which allows for efficient quantum transport simulations in the Dirac regime, to account for elastic strain. We show th…
Pseudomagnetic focusing of valley-polarized beams in strained graphene
Alina Mreńca-Kolasińska, Christophe De Beule, Jia-Tong Shi +4
In addition to spin, the low-energy charge carriers in graphene have two inequivalent valley flavors K and K' related by time-reversal symmetry, which can potentially serve as carr…
Hearing the shape of a Dirac drum: Dual quantum Hall states on curved surfaces
Ioachim Dusa, Denis Kochan, Maximilian Fürst +2
The geometry of a physical system is intimately related to its spectral properties, a concept colloquially referred to as "hearing the shape of a drum". Three-dimensional topologic…
Magnetotransport Signatures of the Radial Rashba Spin-Orbit Coupling in Proximitized Graphene
Wun-Hao Kang, Michael Barth, Aitor Garcia-Ruiz +3
Graphene-based van der Waals heterostructures take advantage of tailoring spin-orbit coupling (SOC) in the graphene layer by proximity effect. At long-wavelength -- saddled by the…
