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 MreÅca-KolasiÅska +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…
Gate-Tunable Resonances and 1D Channel in a Graphene Nanoslide
Christophe De Beule, Ming-Hao Liu, Bart Partoens +1
We present a theory of the graphene nanoslide, a fundamental device for graphene straintronics that realizes a single pseudogauge barrier. We solve the scattering problem in closed…
Dimensional and doping stability of Peierls charge density waves in arrays of coupled one-dimensional chains
Aitor Garcia-Ruiz, Che-pin Hsu, Che-Pin Hsu +2
The Peierls instability, the spontaneous dimerization of a one-dimensional metallic chain at half filling, is a paradigmatic mechanism for charge-density-wave (CDW) formation. Here…
Anisotropic transport in ballistic bilayer graphene cavities
Florian Schoeppl, Alina Mrenca-Kolasinska, Ming-Hao Liu +3
Closing the gap between ray tracing simulations and experimentally observed electron jetting in bilayer graphene (BLG), we study all-electronic, gate-defined BLG cavities using tig…
Pseudomagnetotransport in Strained Graphene
Alina MreÅca-KolasiÅska, Christophe De Beule, Jia-Tong Shi +4
In graphene, long-wavelength deformations that result in elastic shear strain couple to the low-energy Dirac electrons as pseudogauge fields. Using a scalable tight-binding model,…
