Electric manipulation of domain walls in magnetic Weyl semimetals via the axial anomaly
Julia D. Hannukainen, Alberto Cortijo, Jens H. Bardarson +1
We show how the axial (chiral) anomaly induces a spin torque on the magnetization in magnetic Weyl semimetals. The anomaly produces an imbalance in left- and right-handed chirality…
Many-body localization in a fragmented Hilbert space
Loïc Herviou, Jens H. Bardarson, N. Regnault
We study many-body localization (MBL) in a pair-hopping model exhibiting strong fragmentation of the Hilbert space. We show that several Krylov subspaces have both ergodic statisti…
Exact lattice-model calculation of boundary modes for Weyl semimetals and graphene
Vardan Kaladzhyan, Sarah Pinon, Jens H. Bardarson +1
We provide an exact analytical technique to obtain within a lattice model the wave functions of the edge states in zigzag- and bearded-edge graphene, as well as of the Fermi-arc su…
localization landscape for highly-excited states
Loïc Herviou, Jens H. Bardarson
The localization landscape gives direct access to the localization of bottom-of-band eigenstates in non-interacting disordered systems. We generalize this approach to eigenstates a…
