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 on the campus of Ecole Polytechnique, buildings 5 and 6. The reception offices are located in "building 6" , offices 06.1046 and 06.1045.

From quantum gravity to conformal tensor models

Abstract:
I will present an overview of the path leading from non-perturbative approaches to quantum gravity to the recent development of field theories in the so-called "melonic limit".
Along such path one encounters topics such as asymptotic safety, dynamical triangulations, tensor models, AdS/CFT duality, and more. I will try to make sense of all that.

Urko Reinosa fait partie des 143 « Outstanding Referees » choisis par les éditeurs des journaux Physical Review en 2019. Ces outstanding referees sont sélectionnés parmi les 71000 referees en activité.

Voici le texte officiel :

Instituted in 2008, the Outstanding Referee program expresses appreciation for the essential work that anonymous peer reviewers do for our journals. Each year a small percentage of our 71,000 active referees are selected and honored with the Outstanding Referee designation. Selections are made based on the number, quality, and timeliness of referee reports as collected in a database over the last 30 years. A full listing and further details on the program are available here: http://journals.aps.org/OutstandingReferees.

PhD defense at the LPTHE library (Paris) on Tuesday, 4th of september, at 2pm

Charles Cosnier Horeau

"Amplitudes BPS et fonctions automorphes en théorie des cordes"

Abstract: I will present the idea of black hole microstate counting in string theory vacua with extended supersymmetry (N=4), and explain how the degeneracy of certain BPS black holes in four dimension can be extracted from exact couplings in the low energy effective action of a three dimensional model. This set of conjectures will be motivated with supersymmetry constraints, non-perturbative symmetries, and agreement with known results from the literature.
