"Revolutionary Quantum Window Unveiled"
Researchers at HZB have developed an innovative technique to precisely measure minuscule temperature variations in the thermal Hall effect, overcoming previous limitations caused by thermal noise. This advancement sheds light on the behavior of coherent multi-particle states in quantum materials and their interactions with lattice vibrations. The team's novel sample rod and measurement method have significantly reduced interference signals and noise, allowing for high-resolution and reproducible measurements. The next step involves using this technique to investigate the topological properties of lattice vibrations in quantum materials.
