Spin-based information processing is a viable alternative to charge-based approaches, enabling low-power devices. In magnetically ordered systems, spin information can be transported via the
We extend the controlled displacement interaction between a qubit and a harmonic oscillator to the multiqubit (qudit) case. We define discrete quadratures of the qudit and show how the qudit state
We formulate a theoretical description of antiferromagnetic magnons and their transport in terms of an associated pseudospin. The need and strength of this formulation emerges from the
Hybrid platforms that couple microwave photons to collective spin excitations offer promising routes for coherent information processing, yet conventional magnets face inherent trade-offs among
Correlations in squeezed superradiant bursts are shown to be entangled globally, but classical locally.
We study the collective decay of an initially inverted ensemble of two-level emitters into a squeezed photonic reservoir. By using a quantum-state diffusion approach to unravel the emission process,
We study the collective emission of a disordered array of N excited two-level atoms into a one-dimensional photonic waveguide. In the perfectly ordered case, where atoms are spaced by exact integer
The superradiant phase transition in the dissipative Dicke lattice model, driven by on-site collective atom-photon interactions and inter-site photon hopping, is a cornerstone of nonequilibrium

Where Does Helium Come From?
In general, helium is not a rare element in our universe. On the contrary, it is the second-most abundant element in the observable universe, after hydrogen. It
Tip-enhanced Raman spectroscopy (TERS) combines inelastic light scattering well below the diffraction limit down to the nanometer range and scanning probe microscopy and, possibly, spectroscopy. In

Hybrid systems aim to couple two properties to gain novel functionalities. They are the basis of transducers and are presently considered for various quantum applications. Our research focusses on
The mechanical properties of thin films can vary significantly due to variations in the deposition process. Monitoring these properties is essential when, e.g., engineering micro-mechanical devices.
We study the directed transport of bosons along a one dimensional lattice in a dissipative setting, where the hopping is only facilitated by coupling to a Markovian reservoir. By combining numerical
Magnetic tunnel junctions (MTJs) offer a promising pathway toward energy-efficient neuromorphic computing due to their nanoscale footprint, nonvolatile switching, and intrinsic nonlinear dynamics
We experimentally demonstrate the generation of spin-wave frequency combs based on the nonlinear interaction of propagating spin waves in a microstructured waveguide. By means of time- and
