Giant Conductance Enhancement in Graphene Nanoscrolls via Interlayer-Coupled States
Jia-Cheng Li, Ying-Je Lee, Yu An Cheng +6
Graphene nanoscrolls form a unique radial superlattice whose geometry enables transport behaviors distinct from their flat counterparts. We theoretically demonstrate that rolling a…
Tunable Chern superconductivity of PtBi in slab geometry
Luca Ketmaier, Jeroen van den Brink, Ion Cosma Fulga
Recent experiments indicate that PtBi is a Weyl semimetal whose surfaces become topological superconductors with i-wave gap symmetry at low temperature. The bulk hosts 12 Weyl…
Genus-protected higher-order topological phases
Shahroze Shahab, Hui Liu, Daniel Varjas +1
Higher-order topological phases (HOTPs) feature protected gapless modes on boundaries of higher codimension, such as the corners or hinges of a crystal. They are understood as bein…
Dirac semimetal phases in chiral carbon nanoscrolls
Tzu-Ching Hsu, Jhih-Shih You, Hsiu-Chuan Hsu +1
Chirality induced by rolling a two-dimensional material into a spiral geometry reshapes its electronic band structure. In this work, we theoretically investigate the topological pr…
Non-Hermitian topology of quantum spin-Hall systems to detect edge-state polarization
Raghav Chaturvedi, Ion Cosma Fulga, Jeroen van den Brink +1
We study the non-Hermitian topology of multi-terminal transport in a quantum spin-Hall device described by the Bernevig-Hughes-Zhang model. We show that breaking time-reversal symm…
