The Institute for Solid State Research is one of five institutes constituting the Leibniz Institute for Solid State and Materials Research Dresden (IFW Dresden). The IFW Dresden is financed by the German and the Saxonian state in equal parts and employs roughly 500 people. Its mission is to conduct fundamental and application-oriented research, with focus on materials and phenomena that are promising for technological applications. At the Institute for Solid State Research of IFW Dresden we host under one roof the synthesis and crystal growth of novel quantum and nano-materials, a wide portfolio of experimental techniques that helps us understand their physical properties, and the exploration of their potential applications in fields from electronics to medicine. An important aspect of our work is the continuous improvement and development of experimental techniques. At our institute we are active in the training of technicians and researchers, with approximately 7 of our young researchers obtaining their PhD degree every year.

Topological materials represent one of the most promising areas of research in condensed matter physics, offering potential breakthroughs in dissipationless electronics and error-free quantum computing. The combination of non-trivial topology and superconductivity opens pathways to new quantum devices, and the discovery of intrinsic materials in which these properties coexist marks an important frontier in modern condensed matter physics.
Trigonal PtBi₂ has recently emerged as a candidate of particular interest, identified as the first example of a superconducting type-I Weyl semimetal [1–6]. However, several aspects of this compound remain unresolved, including its complex band structure and the nature of its superconducting transition. Transport measurements on bulk single crystals have shown a superconducting critical temperature of approximately 600 mK, whereas ARPES measurements reveal a superconducting transition in the topological surface states at a different temperature, around 15 K, without a corresponding anomaly in resistivity. In addition, recent AC susceptibility experiments indicate that the surface superconducting state exhibits fast superconducting fluctuations.
During this internship, the transport properties of trigonal PtBi₂ will be investigated to identify possible signatures of these superconducting fluctuations.
