Crystalline phases in chiral ferromagnets: Destabilization of helical order
I. Fischer, N. Shah, A. Rosch
In chiral ferromagnets, weak spin-orbit interactions twist the ferromagnetic order into spirals, leading to helical order. We investigate an extended Ginzburg-Landau theory of such…
Field-tuned quantum critical point of antiferromagnetic metals
I. Fischer, A. Rosch
A magnetic field applied to a three-dimensional antiferromagnetic metal can destroy the long-range order and thereby induce a quantum critical point. Such field-induced quantum cri…
Weak spin-orbit interactions induce exponentially flat mini-bands in magnetic metals without inversion symmetry
I. Fischer, A. Rosch
In metallic magnets like MnSi the interplay of two very weak spin-orbit coupling effects can strongly modify the Fermi surface. In the absence of inversion symmetry even a very sma…
Restoration of supersymmetric Slavnov-Taylor and Ward identities in presence of soft and spontaneous symmetry breaking
I. Fischer, W. Hollik, M. Roth +1
Supersymmetric Slavnov-Taylor and Ward identities are investigated in presence of soft and spontaneous symmetry breaking. We consider an abelian model where soft supersymmetry brea…
