Tunable phonon-driven magnon-magnon entanglement at room temperature
Yuefei Liu, Andrey Bagrov, Anders Bergman +7
We report the existence of entangled steady-states in bipartite quantum magnonic systems at elevated temperatures. We consider dissipative dynamics of two magnon modes in a biparti…
Dynamic Magnetoelastic Boundary Conditions and the Pumping of Phonons
Takuma Sato, Weichao Yu, Simon Streib +1
We derive boundary conditions at the interfaces of magnetoelastic heterostructures under ferromagnetic resonance for arbitrary magnetization directions and interface shapes. We app…
Difference between angular momentum and pseudoangular momentum
Simon Streib
In condensed matter systems it is necessary to distinguish between the momentum of the constituents of the system and the pseudomomentum of quasiparticles. The same distinction is…
Angular Momentum Conservation and Phonon Spin in Magnetic Insulators
Andreas Rückriegel, Simon Streib, Gerrit E. W. Bauer +1
We develop a microscopic theory of spin-lattice interactions in magnetic insulators, separating rigid-body rotations and the internal angular momentum, or spin, of the phonons, whi…
Damping of magnetization dynamics by phonon pumping
Simon Streib, Hedyeh Keshtgar, Gerrit E. W. Bauer
We theoretically investigate pumping of phonons by the dynamics of a magnetic film into a non-magnetic contact. The enhanced damping due to the loss of energy and angular momentum…
Magnetomechanical coupling and ferromagnetic resonance in magnetic nanoparticles
Hedyeh Keshtgar, Simon Streib, Akashdeep Kamra +2
We address the theory of the coupled lattice and magnetization dynamics of freely suspended single-domain nanoparticles. Magnetic anisotropy generates low-frequency satellite peaks…
