Peter Eder was member of the Gross group at WMI as a master and Ph.D. student between 2012 and 2021.
Master Thesis: Dual-path Receiver for State Reconstruction of Propagating Quantum Microwaves
We study the interaction of surface acoustic waves with spin waves in ultrathin CoFeB/Pt bilayers. Because of the interfacial Dzyaloshinskii–Moriya interaction (DMI), the spin wave dispersion is
Angular momentum transport is one of the cornerstones of spintronics. Spin angular momentum is not only transported by mobile charge carriers but also by the quantized excitations of the magnetic
From the everyday experience one normally identifies organic materials as electrical insulators. However, there is a class of synthetic molecular charge-transfer salts, which exhibit metallic

Quantum teleportation goes microwave
An international team headed by physicists from the Walther-Meißner-Institute (WMI)
We study the ordering of spins, the magnetization dynamics, and the spin transport in magnetic materials to understand the formation of complex spin textures, their high-frequency response and the
The controlled deposition of (ultra)thin films and compex heterostructures is key for the successful investigation of quantum effects in solid-state devices and the implementation of novel electronic
Superconducting circuits have become a key platform in the field of quantum technology. This work contributes to the field of microwave quantum photonics by scattering experiments of microwave

Liquid Helium Pump
Optimization of the Energy Efficiency of Helium Liquefaction Systems
For the operation of a helium liquefaction plant besides operational safety the most crucial figure of merrit
A Submersible Pump for Liquid Helium
Because the storage vessels for liquid helium only have small openings for installing a pump, small dimensions at large pump capacity are key requirements.
We report the levitation of a superconducting lead-tin sphere with 100 μm diameter (corresponding to a mass of 5.6 μg) in a static magnetic trap formed by two coils in an anti-Helmholtz
The WMI Helium Liquefaction Plant
A Long Tradition in Helium Liquefaction
The Walther-Meißner-Institute (WMI) has been operating a helium liquefaction plant for more than 60 years and supplies the

Noise characterization of impedance-matched parametric amplifiers (experiment)
An Impedance-Matched Parametric Amplifier (IMPA) is a particular type of
Ferroelectricity, where electronic degrees of freedom determine the polar order—thereby enabling fast switching and phase control—is an important research field in current condensed-matter physics.
Non-reciprocal magnonic devices (experiment)
Spin waves (magnons) are the quantized excitations of the magnetic lattice in solid state systems. The field of magnonics is exploring concepts to use
