# The Beg Rohu Summer School of Physics

The Beg Rohu Summer school is an international school of statistical physics.

It takes place at the French National Sailing School (Ecole Nationale de Voile), located on the site of Beg Rohu, in the village Saint Pierre Quiberon , on the peninsula of Quiberon in southern Brittany.

Every year it gathers together 50 participants: half PhD students and half young and confirmed researchers. The aim of the school is twofold: providing for the participants a solid and advanced knowledge of main topics in statistical physics and condensed matter, but also giving rise to interactions between confirmed researchers. Ideally, the outcome of each session is a boost in the research subjects covered by the lectures both because of the excellent training and of the emergence of fruitful interactions between participants. To this aim, each lecture progressively goes from the basics to the current research edge. Lectures and professors are chosen so that the topic of the session is tackled from different points of view; questions and answers sessions are organized in order to foster interactions between students and lecturers.

Lecturers are chosen both for the important role they played in the development of the research subjects covered at the school and their pedagogical capability. Lessons are all given on blackboard (except for showing experimental curves, movies, etc).

The Beg Rohu Summer School is run by the Physics Department of ENS Paris and affiliated to the Institute of theoretical physics of CEA.

## An atypical summer school

The Beg Rohu summer school was born in 1984, because of the passion of its organizer for both physics and sailing. These two worlds, which both require hard work, thinking and concentration, met on the peninsula of Quiberon where lectures on statistical mechanics were given during one month every summer. Along the years, the school acquired the nickname "Beg Rohu" because of its location at the French National Sailing School. This summer school took place until 1997.

## The participants

PhD students, postdocs, young and senior researchers are all welcome to apply to the Beg Rohu school. A proportion of half PhD students and half young and confirmed researchers would be ideal for allowing both pedagogical lectures and dynamic interactions.

## The lectures and the professors

The aim of the school is twofold: providing for the participants a solid and advanced knowledge of main topics in statistical physics and condensed matter, but also giving rise to interactions between confirmed researchers. Ideally, the outcome of each session will be a boost in the research subjects covered by the lectures both because of the excellent training and of the emergence of fruitful interactions between participants. To this aim, each lecture progressively goes from the basics to the current research edge. Lectures and professors are chosen so that the topic of the session is tackled from different points of view; questions and answers sessions are organized in order to foster interactions between students and lecturers.

Lecturers are chosen both for the important role they played in the development of the research subjects covered at the school and their pedagogical capability. Lessons will be all given on blackboard (except for showing experimental curves, movies, etc).

## The French National Sailing School

The French National Sailing School (Ecole Nationale de Voile), located on the site of Beg Rohu, in Saint Pierre Quiberon, is devoted to the training of sailing teams at the national and regional levels and to the professional training of future sailing teachers. It also has a department of research and development.

## Training

Sailing lessons will take place in the afternoon from 1.30 pm to 5 pm. Several types of courses are planned: 8 meters sailing boat, catamaran, dinghy, windsurf and surf. The French National Sailing school will provide the instructors and the boats. Participants wishing to attend sailing courses will have to pay a participation fee of 150 euros (other than the summer school tuition of 1200 euros).

Applications are closed. The selection of participants will take place at the end of April. Applicants will be informed shortly after.

We will run the Beg Rohu summer school taking all the appropriate health measures that will be needed to guarantee a safe environment, in particular all students will have a single room and the lecture room will have a good aeration system. All participants will be required to have completed their World Health Organization-approved vaccination schedule two weeks before the school or earlier.
