The scientific part of the school will consist of three main elements:

1. Morning: 3 one-hour lectures in the morning

2. Late afternoon: 1 hour of short presentations given by the participants of the school (voluntary, but strongly encouraged)

3. Early evening: Computational and experimental tutorials/labs.

The early afternoon will be free for discussions, project work or leisure activities.

Lectures begin on Tuesday, 10th of January at 8.45 am and finish Friday noon, 20th of January. Sunday is free.

Arrival at Les Houches, Ecole de Physique on Monday the 9th, in the afternoon after 15:00. Departure from Les Houches, Ecole de Physique on Friday the 20th, after lunch.
