Helium-4 Resources and their Accessibility
Helium-4 is considered a critical raw material (CRM) and, so far, has often been overlooked in the resource sustainability literature compared to metals

Wireless power transfer (WPT) systems have emerged as a key technology for the future charging
infrastructure. Besides full system efficiency, the power densities of the transmission coils are key
We systematically study the performance of compact lumped element planar microwave Nb70Ti30N (NbTiN) resonators operating at 5 GHz in external in-plane magnetic fields up to 440 mT, a broad
Christoph Utschick was member of the Gross group at WMI as a master and Ph.D. student between 2017 and 2021.
Master Thesis: Inductively Coupled Nano-Electromechanics in Flux Tunable Superconducting
Technical Description of the WMI Helium Pump
A vertical cross-section, a horizontal cross-section along the line A-B and a vertical cross-section of part of the pump systems is shown in the
The European Union has awarded €25 million to the SUPREME consortium, consisting of 23 European companies and research organisations, including WMI.
Over the past two decades, the helium price has been strongly increasing. The reason is a growing demand and a change in supply chains. Although helium prices were doubling from 2002 to 2012, both
Luis Flacke was member of the Gross groups as a Master and Ph.D. Student between 2017 and 2021.
Master Thesis: Spin Pumping and Spin Wave Damping in Co25Fe75 Thin Film Heterostructures (2018) Ph.D.
We investigate the spin Hall magnetoresistance (SMR) at room temperature in thin-film heterostructures of antiferromagnetic insulating (0001)-oriented alpha-Fe2O3 (hematite) and Pt. We measure their
The ability to control the Gilbert damping which determines the lifetime of spin information is crucial for designing spintronic and magnonic devices. Thus, controlling the Gilbert damping parameter
Understanding the excitations of quantum materials is essential for unraveling how their microscopic constituents interact. Among these, particle-hole excitations form a particularly important class,
Nonequilibrium phase transitions and transport in driven-dissipative systems
While the theory of phase transitions in ground and equilibrium states of condensed matter systems is well established,

Nitin Chelwani was member of the Gross group at WMI as a Ph.D. student between June 2011 and December 2016.
Ph.D. Thesis: Scanning Microscopy and Momentum-Resolved Raman Scattering in Semiconductors
The scientific goals of MOQS are to perform experimental and theoretical quantum simulations of comparatively complex molecular structures as well as electron and energy transfer in molecular
Antiferromagnetic materials promise improved performance for spintronic applications as they are robust against external magnetic field perturbations and allow for faster magnetization dynamics
We describe the results of electronic Raman-scattering experiments in differently doped single crystals of YBCO and BiSCCO. The data in antiferromagnetic insulating samples suggest that at least the
We have optimized the growth of superconducting TaN thin films on SiO2 substrates via dc magnetron sputtering and extract a maximum superconducting transition temperature of Tc = 5 K as well as a
The spin Hall effect in heavy-metal thin films is routinely used to convert charge currents into transverse spin currents and can be used to exert torque on adjacent ferromagnets. Conversely, the
The coupling between electrical, thermal, and spin transport results in a plethora of novel transport phenomena. However, disentangling different effects is experimentally very challenging. We
Polarization- and temperature-dependent Raman data along with theoretical simulations are presented for the Kagome ferromagnet Fe3Sn2. Eight out of nine expected phonon modes are identified. The
Protecting qubits from environmental noise while maintaining strong coupling for fast high-fidelity control is a central challenge for quantum information processing. Here, we demonstrate a novel
Achieving fast and high-fidelity qubit operations is crucial for unlocking the potential of quantum computers. In particular, reaching low gate errors in two-qubit gates has been a long-standing
In easy-plane antiferromagnets, the nature of the elementary excitations of the spin system is captured by the precession of the magnon pseudospin around its equilibrium pseudofield, manifesting
