Channel-selective magnetic filtering in a nodal-line semimetal
Hironmoy Pratihar, Alessandro De Martino, Arijit Kundu
We study quantum transport through a magnetic barrier in a nodal-line semimetal. When the Fermi energy lies near the nodal ring, the Fermi surface has toroidal geometry. Each cross…
Toroidal Fermi-surface geometry and phonon-limited transport in nodal-line semimetals
Aman Anand, Alessandro De Martino
Nodal-line semimetals (NLSs) can display unconventional quasiparticle dynamics and charge transport properties due to their extended band degeneracy and the peculiar geometry of th…
Phonon-driven nodal surface superconductivity of Fermi arcs
Francesco Buccheri, Alessandro de Martino, Jeroen van den Brink
According to recent observations, the topological surface states of Weyl semimetals may develop a superconducting gap, while bulk superconductivity remains absent. What drives the…
Magnetic Bloch bands and Weiss oscillations in Dirac mass superlattices
A. Anand, R. Egger, A. De Martino
We study two-dimensional Dirac fermions in a one-dimensional mass superlattice under a perpendicular magnetic field. Using exact solutions for isolated and finite arrays of domain…
Angular-momentum-selective nanofocusing with Weyl semimetals
Marco Peluso, Alessandro De Martino, Reinhold Egger +1
We investigate the theory of surface plasmon polaritons on a magnetic Weyl semimetal conical tip. We show that the axion term in the effective electrodynamics modifies the surface…
