Dynamical renormalization of the magnetic excitation spectrum via high-momentum nonlinear magnonics
Christoph Schoenfeld, Lennart Feuerer, Julian Bär +9
Controlling macroscopic properties of quantum materials requires the ability to induce and manipulate excited states. The set of collective excitations of a solid is encoded in its…

Magnon squeezing in conical spin spirals
Dennis Wuhrer, Levente Rózsa, Ulrich Nowak +1
We investigate squeezing of magnons in a conical spin spiral configuration. We find that while the energy of magnons propagating along the and the $-\boldsymbol{k}…
