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…

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…
