The LPTENS encompasses approximately forty five researchers working on various areas of theoretical physics. We on the one hand study the quantization of gravity, mainly in the context of string theory, problems in high energy physics (in particular related to the experiments at the LHC collider at CERN), and questions in observational cosmology rooted in recent data. Our second emphasis covers numerous statistical physics problems connected to disordered systems, solid state physics, computer science, complex systems, and biology, often subjecting experimental data to analytical or numerical treatment. Common tools to both fields are the quantum field theory of particles or extended objects, supersymmetry, and the theory of classical or quantum totally integrable or scale invariant systems.

We are a mixed unit (UMR 8549) of the Centre National de la Recherche Scientifique, CNRS, and of the Ecole normale superieure, ENS, associated to the University Pierre et Marie Curie, UPMC.

The LPTENS is one of the five laboratories of the physics department of the Ecole normale supérieure.

We are part of the Research Federations : Département de physique de l’Ecole normale supérieure (FR684) and Fédérations de Recherche Interactions Fondamentales (FR2687).
