Offer Description

The candidate will work on topics in classical general relativity (black holes, gravitational waves, asymptotic structure, symmetries) as well as aspects of the quantum theory (holography).

Study of asymptotic symmetries and memory effects beyond the standard paradigm, and their connection with classical gravitational observables and celestial holography. In particular, the following generalizations will be investigated (among others): cosmological constant, logarithmic terms, pp-waves, asymptotically-FLRW spacetimes, coupling to matter, and hidden symmetries.

The candidate will be primarily based at the Laboratoire de Physique de l'ENS de Lyon, where they will collaborate with Marc Geiller. The theory group also includes Etera Livine, Henning Samtleben, Luca Lionni (among others), as well as postdocs and students. In addition, the candidate is expected to interact with Simone Speziale and Alejandro Perez from CPT Luminy (Marseille).

The successful applicant will be hired for this postdoc position by the CNRS, which gives access to

• 44 days of vacation per year
• a university restaurant for lunch during weekdays
• partial reimbursement of transportation tickets (75%) + up to 300€/year to cover the cost of a "sustainable" transport (such as a bicycle)

A solid knowledge of mathematical general relativity is essential. Good knowledge of numerical tools (Mathematica and related packages) is desirable. The candidate will also be expected to take part in the group's activities and dynamics (seminars, reading groups, hosting visiting researchers, interaction with students).
