The center for Theoretical Physics (CPHT) at Ecole Polytechnique gathers research scientists working in diverse domains of fundamental and applied Physics. The overall coherence is assured by the corpus of common, transposable, mathematical and numerical methods.
CPHT is a joint research unit of CNRS and Ecole Polytechnique, and has a partnership with the Collège de France. His director is Jean-René Chazottes, Senior Researcher at CNRS.
CPHT is on the campus of Ecole Polytechnique, buildings 5 and 6. The reception offices are located in building 6 , offices 06.1046 and 06.1045.

A consolidator grant for random tensors and field theory

Razvan Gurau’s ERC consolidator grant, which starts in September 2019 for a five-year period, could finally provide an explanation for certain phenomena. The CNRS researcher with l'X’s Center for Theoretical Physics will expand his research to include random tensors and field theory. These new aspects could provide an understanding of the link between high and low energy physics, with applications for understanding black holes and condensed matter.

A starting grant for the properties of black holes and quantum gravity

 

Andréa Puhm, CNRS research fellow with the Center for Theoretical Physics at École Polytechnique, was awarded an ERC Starting Grant to assist her in starting a research group on "Information Encoding in Quantum Gravity and the Black Hole Information Paradox". This researcher proposes an original approach by combining subtle long-range effects and string theory to resolve the black hole information loss paradox.

For more information, see our article entitled “Andréa Puhm, Recipient of the 2019 ERC Starting Grant”.

Conférence Light Cone 2019 du 16 au 20 septembre 2019 à l'Ecole Polytechnique

 

 

La série de conférences internationales "Light Cone" joue depuis 1991 un rôle important dans le progrès de la recherche vers une description rigoureuse des hadrons et des noyaux basée sur des méthodes de quantification sur le cône de lumière.

L'édition de cette année (LC2019) réunira du 16 au 20 septembre sur le campus de l'Ecole polytechnique plus d'une centaine d'experts internationaux, principalement des théoriciens en physique des hautes énergies. Elle mettra à l'honneur divers aspects de la chromodynamique quantique allant de la physique hadronique (structure des protons, neutrons, ...) aux ions lourds, des domaines où se distinguent l'Ecole polytechnique et plus généralement la recherche française en physique des particules. Cette édition est organisée par Cédric Lorcé, Professeur Assistant au département de physique et membre du Centre de Physique Théorique.

European project STRONG-2020

 

 

 

The European project STRONG-2020 has obtained a funding of about 10 Million Euro for the next five years. The QCD team of CPHT participates in this collaborative ambitious program which aims at resolving a list of open questions at the forefront of our present knowledge in this field at the frontier of nuclear and particle physics. This includes a full understanding of the tridimensional structure of the proton, the spectroscopy of hadrons and their exotic states and the properties of the hot and dense quark-gluon plasma. This program will help unify and enforce the theoretical and experimental studies of the strong interaction, a vivid subject that attracts an active community of about 2500 researchers in Europe.
