The Institut de Physique Théorique (IPhT) is a laboratory of fundamental research, located in Saclay, about 20 km south-west of Paris.

The research performed at the IPhT aims at better understanding the laws which govern our universe and its organisation. It encompasses most of the great subjects of modern theoretical physics:

The IPhT comprises about fifty permanent physicists (2/3 CEA, 1/3 CNRS), about thirty PhD students and postdocs, assisted by a support staff of about ten people. The IPhT also hosts permanently many short term visitors.


Workshop GATIS : Integrability and Gauge Theories   

Le réseau GATIS organise du 11 au 13 mars 2015 (Paris, Institut Henri Poincaré) un atelier de formation pour ses étudiants.

La première journée sera consacrée à des présentations scientifiques par des jeunes membres du réseau et des intervenants extérieurs.

Le programme est accessible sur la page web :

Liouville Quantum Gravity on the Riemann Sphere   

imgIn 1981, the famous theoretician A. Polyakov introduced the quantum Liouville theory as a model for the quantized string. This theory “quantizes” the Liouville equation R=-1 of classical geometry, which characterizes Riemann surfaces with negative curvature. It is thus a quantum theory of gravity, where the geometry of a two dimensional space-time in quantized (1 time dimension + 1 space dimension).

Liouville theory has remarkable properties. It is a conformal theory (it is endowed with an infinite symmetry group, the same as for string theories and critical systems such as the Ising model in two dimensions). Liouville theory appears, sometimes unexpectedly, in many problems of theoretical physics and of pure mathematics. It has been therefore very much studied via the methods of Conformal Field Theory and of Integrable Systems. But it is also related, in a deep but still partially understood way, to combinatorial models where space-time is discretized as a random lattice (random maps, matrix models). In these two approaches (continuous and discrete) the IPhT has brought major contributions.

Recently a third player entered this arena: probability theory! It already led to a better ...

20ème conférence Itzykson, Surfaces et géométries aléatoires, 10-12 juin 2015   

imgThe 20th Itzykson Conference will be held at the Institute of Theoretical Physics in Saclay from June 10 to 12, 2015. This annual conference, honouring the memory of the famous theoretical physicist Claude Itzykson, will be devoted this year to Random Surfaces and Random Geometry and will cover the following topics :
 - random maps, random surfaces and Liouville theory,
 - random geometries in higher dimensions, quantum gravity and string theory,
 - random geometries in condensed matter and biophysics, complex systems and social sciences.

The list of speakers, registration form, and further practical information, are available on the webpage :

Looking forward to seeing you in Saclay in June,

  The organizers, Jérémie Bouttier, François David and Bertrand Eynard
