Collective excitations and divergent spin currents in non-centrosymmetric superconductors
Markus Lysne, Philipp Werner, Nikolaj Bittner
We study the collective modes in a non-centrosymmetric superconductor with Rashba spin-orbit coupling under laser irradiation. The concept of Anderson Pseudospin Resonance allows t…

High harmonic generation in altermagnets
Philipp Werner, Markus Lysne, Yuta Murakami
We study high harmonic generation in altermagnetic metals with and without spin-orbit coupling. The altermagnetism manifests itself in the magnetic field dependence of the low harm…

Many-body effects on high-harmonic generation in Hubbard ladders
Yuta Murakami, Thomas Hansen, Shintaro Takayoshi +2
We show how many-body effects associated with background spin dynamics control the high-harmonic generation (HHG) in Mott insulators by analyzing the two-leg ladder Hubbard model.…
