For applications making use of magnonic spin currents damping effects, which decrease the spin conductivity, have to be minimized. We here investigate the magnon transport in a yttrium iron garnet
The precession of magnon pseudospin about the equilibrium pseudofield, the latter capturing the nature of magnonic eigen-excitations in an antiferromagnet, gives rise to the magnon Hanle effect. Its

We report on the magnetic behavior of oxidized-CoxFe1−xS2 nanocrystals as they assemble to form nanoparticles. The morphologies show a typical NP size of around 250–100 nm and NC sizes of around 7
We analyze the implementation of high-fidelity, phonon-mediated gate operations and quantum simulation schemes for spin qubits associated with silicon vacancy centers in diamond. Specifically, we

We study the interaction of Rayleigh and shear horizontal surface acoustic waves (SAWs) with spin waves in thin Ni films on a piezoelectric LiTaO3 substrate, which supports both SAW modes
Ferromagnetic resonance spectroscopy is a microwave spectroscopy technique which allows to investigate magnetic excitations in magnetic systems.
Light-matter interaction in optomechanical systems is the foundation for ultra-sensitive detection schemes as well as the generation of phononic and photonic quantum states. Electromechanical systems
In recent years, layer-by-layer heteroepitaxy has become a versatile tool for depositing novel materials not accessible in bulk form. While it is possible to control the mono layer sequence on an
In prototype ferromagnet-antiferromagnet interfaces we demonstrate that surface acoustic waves can be used to identify complex magnetic phases arising upon evolution of exchange springs in an applied
What Do We Use Helium-4 For?
Today, more than one-third of the helium consumption is for cryogenic applications (mostly MRI: 22%, laboratory use: 10%, other cryogenics: 4%). Complementary use for

Overview
Over the past century, our more and more refined understanding of light-matter interactions at the level of single atoms and photons has led to ultra-precise tests of quantum mechanical principles
