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…
Emergent spatiotemporal order and nonreciprocity in driven-dissipative nonlinear magnetic systems
Vincent Flynn, Benedetta Flebus
The identification of platforms with independently tunable nonlinearity and non-Hermiticity promises a quantitative route to far-from-equilibrium universality across many-body syst…
Generating single- and many-body quantum magnonic states
Violet Williams, Jayakrishnan M. P. Nair, Yaroslav Tserkovnyak +1
The growing interest in quantum magnonics is driving the development of advanced techniques for generating, controlling, and detecting non-classical magnonic states. Here, we explo…
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…
