Brillouin Light Scattering Spectroscopy of Propagating Magnons at Sub-Kelvin Temperatures
David Schmoll, Nikolai Kuznetsov, Phillip Rehberger +8
Coupling light to magnetic excitations in the form of spin waves underpins both the optical study of magnetism and emerging schemes for quantum transduction, positioning the quanta…
Magnetic Materials for Quantum Magnonics
Rostyslav O. Serha, Carsten Dubs, Andrii V. Chumak
Quantum magnonics studies the quantum properties of magnons, the quanta of spin waves, and their application in quantum information processing. Progress in this field depends on id…
Quantum State Preparation of Ferromagnetic Magnons by Parametric Driving
Monika E. Mycroft, Rostyslav O. Serha, Andrii V. Chumak +1
We propose a method to prepare and certify Gaussian quantum states of the ferromagnetic resonance spin-wave modes in ferromagnets using a longitudinal drive. Contrary to quantum op…
Ultra-long-living magnons in the quantum limit
Rostyslav O. Serha, Kaitlin H. McAllister, Fabian Majcen +8
Solid-state platforms based on bosonic quasiparticles offer a compelling route toward on-chip quantum information technologies scalable to nanometer dimensions. Coherence time, a k…
Unified theory of magnetization temperature dependence in ferrimagnets
Rostyslav O. Serha, Anna Pomyalov, Andrii V. Chumak +1
Recent advancements in spintronics and fundamental physical research have brought increased attention to the rare-earth-based magnetically ordered materials. One of the important p…
Long-range propagating paramagnon-polaritons in organic free radicals
Sebastian Knauer, Roman Verba, Rostyslav O. Serha +5
Materials are commonly distinguished by their magnetic response into diamagnetic, paramagnetic, and magnetically ordered (ferro-, ferri-, and antiferromagnetic) phases. Diamagnets…
