Surface magnon spectra of nodal loop semimetals

A Alassaf, J Koltai, L Oroszlány - Physical Review B, 2024 - APS
In this paper, we establish a connection between the bulk topological structure and the
magnetic properties of drumhead surface states of nodal loop semimetals. We identify the …

Surface quantum critical phenomena in disordered Dirac semimetals

E Brillaux, AA Fedorenko, IA Gruzberg - Physical Review B, 2024 - APS
We study a non-Anderson disorder driven quantum phase transition in a semi-infinite Dirac
semimetal with a flat boundary. The conformally invariant boundary conditions, which …

Disorder-induced instability of a Weyl nodal loop semimetal towards a diffusive topological metal with protected multifractal surface states

JS Silva, M Gonçalves, EV Castro, P Ribeiro… - Physical Review B, 2025 - APS
Weyl nodal loop semimetals are gapless topological phases that, unlike their insulator
counterparts, may be unstable to small perturbations that respect their topology-protecting …

Stable nodal line semimetals in the chiral classes in three dimensions

F Abdulla, G Murthy, A Das - arxiv preprint arxiv:2401.02966, 2023 - arxiv.org
It has been realized over the past two decades that topological nontriviality can be present
not only in insulators but also in gapless semimetals, the most prominent example being …

Topological nodal line semimetals with chiral symmetry

F Abdulla, G Murthy, A Das - arxiv preprint arxiv:2311.18667, 2023 - arxiv.org
Topological semimetals in three dimensions display band-touchings at points (Weyl or Dirac
semimetals) or nodal lines in the Brillouin zone. Weyl semimetals can occur with internal …
