Laboratory of theoretical physics ENS

About forty five people work at the LPTENS. Our research encompasses many areas in 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.

A NEW PARTICLE has been discovered with 99,9999% confidence level
at CERN by the collaborations ATLAS and CMS at the LHC. It has the characteristics of the famous
HIGGS BOSON whose hunt has long been one of the top priorities for particle physics.



The LabEx Departmental grant will fund three postdoctoral positions in, amongst other fields, theoretical physics, starting September 1, 2015, for the duration of two or three years.

The Institute of Theoretical Physics Philippe Meyer will fund two postdoctoral positions in theoretical physics, starting from October 1, 2015 for the duration of two or three years. The application proceeds via Academic Jobs Online.


The Philippe Meyer Prize in Theoretical Physics 2014 is awarded to Zohar Komargodski.

Postdoctoral positions in Theoretical Physics

The Laboratoire de Physique Théorique de l’École normale supérieure (Paris) invites applications for approximately six postdoctoral positions in theoretical physics, starting September 1, 2014.

The positions are variously funded by national ANR grants, a European ERC grant, the Institut Philippe Meyer as well as a Departmental LabEx grant.

Projects in particle and astroparticle physics, field and string theory, statistical physics and its applications in condensed matter physics, biophysics and information theory, are especially welcome.

The deadline for submission depends on the offer. A CV, a research project and three letters of recommendation should be included. We recommend that applicants apply to all relevant sources of funding.
