Dynamical metastability and transient topological magnons in interacting driven-dissipative magnetic systems
Vincent P. Flynn, Lorenza Viola, Benedetta Flebus
Metastability, i.e., partial relaxation to long-lived, quasi-stationary states before true asymptotic equilibrium sets in, emerges ubiquitously in classical and quantum dynamical s…
Chemical potential of magnon polarons
Violet Williams, Benedetta Flebus
Using a rotationally invariant formulation of spin-lattice coupling, we derive a rigorous definition of the chemical potential for magnon-polaron quasiparticles in collinear ferrom…
Coupling Magnons to an Opto-Electronic Parametric Oscillator
Junming Wu, Shihao Zhou, Benedetta Flebus +1
Hybrid magnonic systems have emerged as versatile modular components for quantum signal transduction and sensing applications owing to their capability of connecting distinct quant…
Angular Momentum Fluctuations in the Phonon Vacuum of Symmetric Crystals
Rule Yi, Violet Williams, Benedetta Flebus
Although time-reversal and inversion symmetry constrain the angular momentum of each phonon mode to vanish, we show that the vacuum state of crystals with such symmetries can never…
