Magnetically induced polarization in centrosymmetric bonds
Igor Solovyev, Ryota Ono, Sergey Nikolaev
We reveal the microscopic origin of electric polarization induced by noncollinear magnetic order. We show that in Mott insulators, such is given by all possible…

Surface band characters of Weyl semimetal candidate material MoTe revealed by one-step ARPES theory
Ryota Ono, Alberto Marmodoro, Jakub Schusser +7
The layered 2D-material MoTe in the T crystal phase is a semimetal which has theoretically been predicted to possess topologically non-trivial bands corresponding to Weyl f…

Fingerprints of spin-current physics on magnetoelectric response in the spin- magnet BaCuGeO
Ryota Ono, Sergey Nikolaev, Igor Solovyev
The single-site anisotropy vanishes for the spin-1/2 as a consequence of Kramers degeneracy. We argue that similar property holds for the magnetically induced electric polarization…
