Electric and spin current vortices in altermagnets
Arsen Herasymchuk, Karl Bergson Hallberg, Erik Wegner Hodt +3
Altermagnets constitute a class of collinear magnets with momentum-dependent spin splitting and vanishing net magnetization. Direct observation of the characteristic altermagnetic…
Surface states and finite size effects in triple-fold semimetals
A. Yu. Prykhodko, E. V. Gorbar, P. O. Sukhachov
Triple-fold or pseudospin-1 semimetals belong to a class of multi-fold materials in which linearly dispersive bands and flat bands intersect at the same point, forming triple-fold…
Viscoelastic response and anisotropic hydrodynamics in Weyl semimetals
A. A. Herasymchuk, E. V. Gorbar, P. O. Sukhachov
We study viscoelastic response in Weyl semimetals with broken time-reversal symmetry. The principal finding is that topology and anisotropy of the Fermi surface are manifested in t…
Electron binding energy of a donor in bilayer graphene with gate-tunable gap
E. V. Gorbar, V. P. Gusynin, D. O. Oriekhov +1
In gapped bilayer graphene, similarly to conventional semiconductors, Coulomb impurities (such as nitrogen donors) may determine the activation energy of its conductivity and provi…
Optical conductivity of bilayer dice lattices
P. O. Sukhachov, D. O. Oriekhov, E. V. Gorbar
We calculate optical conductivity for bilayer dice lattices in commensurate vertically aligned stackings. The interband optical conductivity reveals a rich activation behavior uniq…
Stackings and effective models of bilayer dice lattices
P. O. Sukhachov, D. O. Oriekhov, E. V. Gorbar
We introduce and classify nonequivalent commensurate stackings for bilayer dice or lattice. For each of the four stackings with vertical alignment of sites in two l…
