Chiral phonons driven by chiral cavities
V. A. S. V. Bittencourt, N. Shabala, R. M. Geilhufe +1
Lattice vibrations carrying angular momentum give rise to fundamental phenomena such as the phonon Hall effect and the Einstein-de Haas effect, offering new opportunities for manip…
Overcoming intrinsic material limitations through cavity feedback
M. Ebrahimi, Y. Huang, V. A. S. V. Bittencourt +3
Magnons, the quanta of spin waves, have significant potential for use in modern technologies, especially when strongly coupled to another mode for read-out and control. However, wh…
Magnon-microwave backaction noise evasion in cavity magnomechanics
V. A. S. V. Bittencourt, C. A. Potts, J. P. Davis +1
In cavity magnomechanical systems, magnetic excitations couple simultaneously with mechanical vibrations and microwaves, incorporating the tunability of magnetism and the long life…
Minimal models for nonreciprocal amplification using biharmonic drives
A. Kamal, A. Metelmann
We present a generic system of three harmonic modes coupled parametrically with a time-varying coupling modulated by a combination of two pump harmonics, and show how this system p…
Quantum-Limited Amplification via Reservoir Engineering
A. Metelmann, A. A. Clerk
We describe a new kind of phase-preserving quantum amplifier which utilizes dissipative interactions in a parametrically-coupled three-mode bosonic system. The use of dissipative i…
Transport through single-level systems: Spin dynamics in the nonadiabatic regime
A. Metelmann, T. Brandes
We investigate the Fano-Anderson model coupled to a large ensemble of spins under the influence of an external magnetic field. The interaction between the two spin systems is treat…
