We study the flow of a pure spin current through zinc oxide by measuring the spin Hall magnetoresistance (SMR) in thin film trilayer samples consisting of bismuth-substituted yttri…
Non-symmorphic band degeneracy at the Fermi level in ZrSiTe
Andreas Topp, Judith M. Lippmann, Andrei Varykhalov +4
Non-symmorphic materials have recently been predicted to exhibit many different exotic features in their electronic structures. These originate from forced band degeneracies caused…
Collective electronic excitation in a trapped ensemble of photogenerated dipolar excitons and free holes revealed by inelastic light scattering

Stefan Klingler, Hannes Maier-Flaig, Carsten Dubs +5
The magnetostatic mode (MSM) spectrum of a 300m diameter single crystalline sphere of yttrium iron garnet is investigated using broadband ferromagnetic resonance (FMR). The indi…
Light matter interaction in transition metal dichalcogenides and their heterostructures
Ursula Wurstbauer, Bastian Miller, Eric Parzinger +1
The investigation of 2D van der Waals (vdW) materials is a vibrant, fast moving and still growing interdisciplinary area of research. 2D vdW materials are truly 2D crystals with st…
Overflow of a dipolar exciton trap at high magnetic fields
S. Dietl, K. Kowalik-Seidl, D. Schuh +3
We study laterally trapped dipolar exciton ensembles in coupled GaAs quantum wells at high magnetic fields in the Faraday configuration. In photoluminescence experiments, we identi…
Quantum illumination reveals phase-shift inducing cloaking
U. Las Heras, R. Di Candia, K. G. Fedorov +3
In quantum illumination entangled light is employed to enhance the detection accuracy of an object when compared with the best classical protocol. On the other hand, cloaking is a…
Self-Polarizing Microswimmers in Active Density Waves
Alexander Geiseler, Peter Hänggi, Fabio Marchesoni
An artificial microswimmer drifts in response to spatio-temporal modulations of an activating suspension medium. We consider two competing mechanisms capable of influencing its tac…
Flux-driven Josephson parametric amplifiers: Hysteretic flux response and nondegenerate gain measurements
Stefan Pogorzalek, Kirill G. Fedorov, Ling Zhong +11
Josephson parametric amplifiers (JPA) have become key devices in quantum science and technology with superconducting circuits. In particular, they can be utilized as quantum-limite…
