Transport, refraction, and interface arcs in junctions of Weyl semimetals

F Buccheri, R Egger, A De Martino - Physical Review B, 2022 - APS
We study the low-energy single-electron transport across a junction of two magnetic Weyl
semimetals, in which the anisotropy axes are tilted one respect to the other. Using a two …

Dispersive drumhead states in nodal-line semimetal junctions

F Buccheri, R Egger, A De Martino - Physical Review Research, 2024 - APS
We consider a smooth interface between a topological nodal-line semimetal and a
topologically trivial insulator (eg, the vacuum) or another semimetal with a nodal ring of …

Phonon-limited transport and Fermi arc lifetime in Weyl semimetals

F Buccheri, A De Martino, RG Pereira, PW Brouwer… - Physical Review B, 2022 - APS
Weyl semimetals harbor topological Fermi arc surface states that determine the nontrivial
charge current response to external fields. We study here the quasiparticle decay rate of …

Interfaces of nodal-line semimetals: Drum states, transport, and refraction

M Rudi, A De Martino, K Moors, D Giuliano, F Buccheri - Physical Review B, 2024 - APS
We study transport through interfaces in topological nodal-line semimetal (NLS), focusing on
two geometries: a single interface between two large samples, one NLS and one metal, and …

Fermi arc mediated transport in an inversion symmetry broken Weyl semimetal nanowire and its hybrid junctions

A Pal, P Dutta, A Saha - Physical Review B, 2024 - APS
The emergence of gapless surface states, known as Fermi arcs (FAs), is one of the unique
properties of the novel topological Weyl semimetal (WSM). However, extracting the …

Large optical conductivity of Fermi arc states in Weyl and Dirac semimetal nanowires

W Duan, XD Lu, JF Liu - Physical Review B, 2023 - APS
We theoretically study the band structure and optical conductivity in the Weyl and Dirac
semimetal nanowires. It is found that the Fermi arc states play a crucial role in the optical …
