Extracting higher-order nonlinearities in nanomechanical resonators using the backbone relation
Maria Kallergi, Daniel K. J. BoneÃ, Maximilian Seitner +2
Nanomechanical resonators are a powerful platform for studying nonlinear dynamics with high sensitivity and precision. We explore the nonlinear response of a high-Q nanomechanical…
Hidden quantum correlations in the ground states of quasiclassical spin systems
Levente Rózsa, Dennis Wuhrer, Sebastián A. DÃaz +2
Frustrated spin models may lead to the formation of both classical non-collinear spin structures and unique quantum phases including highly entangled quantum spin liquids. Here, we…
Spin pumping into quantum spin nematic states
Takuto Ishikawa, Wolfgang Belzig, Takeo Kato
We theoretically study spin pumping into a spin-nematic state in a junction system composed of a ferromagnetic insulator and a spin-nematic insulator, described by using the spin-1…
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…
