Quantum sensing composite excitations in an anisotropic ferromagnet via a qubit
Amey S. Rodge, Tarek Moussa, Akashdeep Kamra +1
Ordered magnets harbor intrinsically squeezed ground states and magnonic excitations characterized by entanglement between spins and nonclassical magnon number composition. A pathw…
Microwave-to-optical transduction using magnon-exciton coupling in a layered antiferromagnet
Pratap Chandra Adak, Iris McDaniel, Suvodeep Paul +12
Coherent interfaces between microwave-frequency quantum systems and low-loss optical links are essential for quantum networks. However, existing microwave-optical transducers often…
Unquenched orbital angular momentum as the origin of spin inertia
Tarek Moussa, Darpa Narayan Basu, Ritwik Mondal +1
The recent proposal and observation of spin inertia, and the consequent high-frequency spin nutation mode, have raised key questions for our understanding of magnetization dynamics…
Quantum sensing magnonic number states using a bosonic mode as the probe
Bashab Dey, Sonu Verma, Mathias Weiler +1
Sensing number states of a magnonic mode has been accomplished using a superconducting qubit by realizing an effective dispersive interaction between the two systems. Here, we theo…
Magnon-polaron control in a surface magnetoacoustic wave resonator
Kevin Künstle, Yannik Kunz, Tarek Moussa +6
Strong coupling between distinct quasiparticles in condensed matter systems gives rise to hybrid states with emergent properties. We demonstrate the hybridization of confined phono…
Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
