We invite young Ukrainian researchers (final year BSc studens, MSc students, and PostDocs) to apply for scholarships for a research stay at IFW Dresden in one of three specializations: materials, experiment, or theory. Master thesis will be jointly supervised by KAU and IFW. Deadline for applications has been extended to June 28th!! Learn more here. Would you like to learn more about the facilities and work at IFW? Then join our virtual lab tours in Ukranian language on June 30th.

Our current 10 scholarships holders will report on their work at IFW Dresden on June 29th in a remote meeting with Ukranian and German supervisors. The program is available here.

The 2nd UKRATOP Workshop "Topological Phenomena in Quantum Materials" will take place online on July 1st.

 

 

 


 

About

The scientific goal of the project "Topological order of electrons in solids: New materials, Phenomena & application Concepts" (UKRATOP) is to design new high-quality materials with exceptional surface and edge conditions resulting from their topological nature. The topological stability of the exotic physical properties of these materials can be of tremendous interest to the next generation of information technology.
UKRATOP is funded by the Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung, BMBF) under reference 01DK18002.
