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.

Balt Van Rees, professor at Ecole Polytechnique and member of the Centre for Theoretical Physics, has been awarded an ERC consolidator grant for his QFTinADS project. He will push further a strategy called the “bootstrap”, that aims at better understanding QFTs by exploring very general consistency conditions.
Since 2019 the Department of Physics and Astronomy at Heidelberg University has been awarding two thesis prizes per year, sponsored by the Wilhelm and Else Heraeus Foundation.
Sabine Harribey is one of the 2022 laureates for her work "Renormalization in tensor field theory and the melonic fixed point," carried out jointly at the École polytechnique (CPHT) and at Heidelberg, under the supervision of D. Benedetti and R. Gurau.

Thesis: "Topological Materials, Semimetals and Quantum Information"
Advisor: Karyn Le Hur
Abstract
The objective of this thesis is to study the topological and physical properties of a new class of topological semimetals recently discovered in the group. These semimetals exhibit fractional topological properties due to the particular geometry of their band structure, involving quantum entanglement properties in the Brillouin zone. The first part of this thesis will consist in studying these quantum properties in order to identify the nature of the protection of this topological phase of matter. During this first part of the thesis, we will also be interested in identifying possible experimental protocols, including light-matter interactions protocols, with aim of experimental demonstration of these fractional topological phases by characterizing the properties of thermodynamic and transport observables within these topological phases. Particular attention will be paid to the effects of interactions on the topology of the system. Eventually, the goal is to develop new theoretical and numerical tools for the systematic study and characterization of these fractional topological phases of matter for technological purposes with links to entanglement and quantum information.

The publication of Alexander Friedmann's seminal papers in 1922 marked the birth of modern cosmology. In order to celebrate its centenary, the Friedmann Endowment will fund various scientific actions over the next few years, covering the wide range of themes associated with cosmology, at École Polytechnique and partner institutions, in collaboration with the Foundation of Ecole Polytechnique. The Friedmann Colloquium will be a flag activity, organized by the Physics Department and aimed at a general audience of scientists and science students.
For its first edition of the Friedmann Colloquium, Dr. Frank Eisenhauer from the Max Planck Institute for Extraterrestrial Physics, Munich (Garching) will speak about : THE GALACTIC CENTER BLACK HOLE, THE EFFECTS OF GENERAL RELATIVITY, AND HOW TO OBSERVE THEM

About the Alexander Friedmann Endowment
In 1922 Alexander Friedmann (1888-1925) published a seminal paper, which triggered the advent of modern cosmology. In order to celebrate its centenary, the Alexander Friedmann Endowment supports various scientific activities, covering the wide range of subjects associated with cosmology, at Ecole Polytechnique and its partner institutions. Among these activities, the Friedmann Colloquium is a general seminar addressing an audience of scientists and science students.
Scientific committee : Silke Biermann (CPHT), Jean-René Chazottes (CPHT), Mathieu de Naurois (LLR), Marios Petropoulos (CPHT), Sébastien Renaux-Petel (IAP), Yves Sirois (LLR).
The students conference is organized this year on Friday, November 25, Becquerel amphitheatre.
