The Venue and How to reach it

The event will be hosted by the Technical and Applied Physics Department, school of Physics and Earth Science in lab N211 on the second floor of the N block, the first building on your left on entering through the public entrance on Workshop Road. Please follow the following navigation map link to arrive a the university. Access to the university requires registration with security at the gate, your destination will be N301, 3rd Floor, N-Block in the Physics Department, there is no access restrictions to enter the laboratory.

Setting up Yambo, QE and the tutorials

To be able to follow the school you need a running version of the yambo/QE codes, and the files and databases needed to run the tutorials.

Detailed instructions about the code(s) installation can be found in this dedicated page.

After installing the code you can setup the tutorial files following the instructions provided in the Tutorial files page.

Sunday 19 Feb

For those who will be already in Nairobi we will have a get together & Yambo installation session at the YMCA South C starting from 18:00.
