Lay Summary (German)

Lead
Unter „Quantenmaterialien“ versteht man jene chemischen Verbindungen in denen die quantenmechanische Natur der Elektronen zu ungewöhnlichem Verhalten führt. So zum Beispiel in „topologischen Metallen“, in denen die elektronischen Wellenformen durch mathematische Eigenschaften von Knoten charakterisiert werden. Wenn sich Elektronen anders verhalten als üblichen Metallen und Halbleitern, so könnte dieses zu neuartiger Elektronik und technischen Anwendungen jenseits von Kupfer oder Silizium führen.
Lay summary

Wenn neue, komplexe Materialien entdeckt werden, sind die ersten Proben selten rein genug um die eigentlichen Materialeigenschaften zu untersuchen. Dank moderner Mikroanalytik lassen sich in diesen Proben winzige Partikel identifizieren, in denen das Material in reiner kristalliner Form vorliegt. Mit einem fokussierten Ionenstrahl können diese Mikrokristalle mit Nanometer-Präzision ausgeschnitten werden. So können Mikro-Leiterbahnen als Prototypen neuer Elektronik direkt nach der Entdeckung eines Materials untersucht werden. Im Laufe dieses Projekts werden wir die ersten Mikroelektromechanischen Strukturen (MEMS) aus Hochtemperatur- und Schwerfermionen-Supraleitern entwickeln, in denen wir erstmals die Kopplung mechanischer Bewegung an die elektronischen Eigenschaften dieser Materialien untersuchen können.

Abstract

The often subtle signatures at electronically broken phase transitions in quantum materials call for new approaches to symmetry specific, thermodynamic experimental capabilities. Here we propose to investigate three key questions: (a) the thermodynamic character of the pseudogap in the cuprates; (b) the nature of nematic fluctuations in pnictides; and (c) the topological aspects of heavy fermion matter. We will tackle these open questions by developing new experimental techniques based on single crystal circuits and mesoscale structures shaped by Focused-Ion-Beam microfabrication. Micro-mechanical resonators made from quantum matter will enable measurements of the elastic moduli providing symmetry specific information about phase transitions. Highly integrated thermal transport devices will be fabricated directly from single crystals, enabing the study of heat and charge flow on the micron-scale.
