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.
