About IFAE

The Institut de Física d’Altes Energies (IFAE) is a public consortium of the Generalitat de Catalunya, the Autonomous Government of Catalonia, and the Universitat Autònoma de Barcelona (UAB, a public university) whose main objective is to carry out research and to contribute to the development of high energy physics from a theoretical, experimental and technological point of view. IFAE has the status of a “University Institute" attached to the UAB and its premises are within the campus of the University.

About Theoretical Physics Group and the GravNet project

The theory group of IFAE (Barcelona, Spain) invites applications for one to two postdoctoral research positions in theoretical developments for searches of high frequency gravitational waves in cavities. The positions will start in Fall 2027 and will have a duration of three years. These positions will be funded by the ERC Synergy Grant project GravNet (A General Network for the Search for High Frequency Gravitational Waves). GravNet is dedicated to optimize the searches of high-frequency gravitational waves in a network of electromagnetic cavities, or other set-ups to be conceived during the project. All aspects, from source characterization, response of detectors, network distribution to sensing strategies (in particular leveraging quantum sensing) will be revised, with the goal of building the most precise detector to high frequency gravitational waves in the near future.

GravNet is led by PIs Diego Blas (IFAE/ICREA, Barcelona), Dima Budker (U. Mainz), Claudio Gatti (LNF, Italy) and Matthias Schott (U. Bonn,



Germany; leading PI). The successful candidates will join the GravNet-IFAE group, in charge of developing and optimizing all theoretical aspects of the proposal.

This includes the complete modeling and simulation of the response of the detectors to gravitational waves of different sources, generating realistic sensitivity calculations and exploring different network configurations. These results will be used to design the best strategy for GravNet to detect high frequency gravitational waves.

Job profile and tasks

The candidates should have research expertise in Theoretical Physics, and experience on theoretical work dealing with searches of BSM physics or gravitational waves physics in laboratory set-ups (in particular with quantum sensing techniques) is particularly welcome.
