2022 FELBE/TELBE User Workshop

12 Sept 2022, 13:00 → 14 Sept 2022, 15:45 Europe/Berlin

Hörsaal (HZDR)

In this second edition of the FELBE/TELBE User Workshop, we intend to bring together users of the coherent THz sources of TELBE and FELBE as well as other experts in the field of THz science for extensive discussions of recent results and advances in the study of THz interactions in materials. The program will consist of a combination of invited and contributed talks, as well as an extended poster session. We invite everyone interested to participate and also present their work. As a workshop, we aim to provide ample time for discussion and feedback, making this an excellent forum for presenting new and ongoing research.

Please post our workshop flyer and encourage your colleagues to join us.

 

The workshop topics include:

• Superconductors / Collective Phenomena
• Harmonic Generation
• THz Nanophotonics / THz Nanoscopy
• THz Magnonics / Spintronics
• Phononics
• Bio / Organics
• Status Reports of THz User Facilities
• Keynote Talk:  THz Quantum Optics
