Dear colleagues --

With the deadline for registration and abstract submission coming close (September 04) I wanted to send a last-minute reminder on the 11th Workshop on High Pressure, Planetary and Plasma Physics (11HP4) at the University of Rostock, Germany (September 25-27, 2023). The aim of the workshop is the continued discussion of scientific questions with relevance for extreme planetary environments at high pressures and high temperatures. Such conditions are prevalent in the deep interiors or in the atmospheric envelopes of planets and satellites of our solar system as well as of other star systems.

The following topics will be part of the workshop:
- Dynamic and ultrafast processes in strongly excited matter
- Compression experiments using high-power optical and free electron lasers
- Laboratory experiments using multi-anvil and diamond-anvil cells
- Ab-initio simulation studies for matter under extreme conditions
- Equations of state, petrology, and chemistry of planetary materials
- Melting and phase relations of materials at extreme conditions
- Evolution and structure of giant planet interiors
- Structure, composition, and internal dynamics of solid planets
- Physics and chemistry of impact processes

Visit our website for more information and registration at https://indico.desy.de/event/38127/. Please register and submit your abstract (oral or poster) by September 04, 2023. There is no registration fee.

Confirmed invited speakers are:
- Dario Alfè, University College London, UK
- Karen Appel, European XFEL, Germany
- Roi Baer, The Hebrew University of Jerusalem, Israel
- Razvan Caracas, IPGP Paris, France
- Thomas Duffy, Princeton University, USA
