Talk by Prof. Henrik Rønnow

I will discuss:

Future (Swiss) perspectives for neutron spectroscopy; How to find a room temperature superconductor; The theory of high-temperature superconductivity; and How surfing works - with emphasis on the Heisenberg antiferromagnet in 2D and in 1D:

- The Hubbard heritage providing a consistent 1-band approximation of cuprates
- A curious zone-boundary effect which may signal spinons in 2D
- How to count spinons in 1D
- Decay of spin-waves in 2D and creation of exotic states in 1D
