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…
Spin and thermal current scaling at a -junction of XX spin chains
Domenico Giuliano, Francesco Buccheri
We study the boundary phase diagram and the low-temperature heat and magnetization transport at a -junction of XX spin chains. Depending on the magnetization axis anisotropy bet…
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…
Localized surface plasmons in a Weyl semimetal nanosphere
Francesco M. D. Pellegrino, Francesco Buccheri, G. G. N. Angilella
In this study, we investigate the localized surface plasmon modes of a sub-wavelength spherical nanoparticle composed of a Weyl semimetal, taking into account the axion modificatio…
Nonreciprocal Weyl semimetal waveguide
Marco Peluso, Alessandro De Martino, Reinhold Egger +1
We study a cylindrical plasmonic waveguide consisting of a magnetic Weyl semimetal embedded in a dielectric medium. We determine the dispersion relation of the surface plasmon pola…
Quantum description of Fermi arcs in Weyl semimetals in a magnetic field
Tim Bauer, Francesco Buccheri, Alessandro De Martino +1
For a Weyl semimetal (WSM) in a magnetic field, a semiclassical description of the Fermi-arc surface state dynamics is usually employed for explaining various unconventional magnet…
