Travel report (Yokoyama)

I had the opportunity to spend about a week at the University of Tübingen, where I attended the ASPIRE Symposium 2026. It was a great chance to learn about a variety of research topics and see cutting-edge experiments firsthand.

During the symposium, I had many discussions with researchers from different fields. Through these conversations, I learned a lot, ranging from practical experimental techniques to more theoretical aspects of atomic and quantum physics.

I also had some time to explore Tübingen and visit Tübingen Castle and Hohenzollern Castle. I really enjoyed the beautiful views, unique cityscape, and lively atmosphere.

After the symposium, I visited the University of Stuttgart for laboratory tours. I was amazed by the diversity of research within a single institute, including hot atomic vapor combined with integrated photonics, ion microscopy, dipolar supersolids, quantum networks based on cavity-coupled atoms, and circular Rydberg atoms with control of the ionic core.

What fascinated me especially was how carefully and boldly each experimental system had been designed around its scientific goal. Some setups also had a long history, and I was impressed by how they have continued to evolve while enabling research at the forefront of the field.

Another strong impression was how much the researchers genuinely seemed to enjoy their work. Their enthusiasm for developing new techniques, exploring unconventional ideas, and discussing the underlying physics was very inspiring. Overall, the visit gave me many new ideas and renewed motivation for my own research.
