ERC Funded Postdoctoral Positions in Theoretical Particle Physics, Theoretical Cosmology/Gravitation Institut de Física d'Altes Energies in Spain

The IFAE Theory Division in Barcelona is seeking one to two PhD researchers to work on the theoretical development of searches for high-frequency gravitational waves in cavities and other laboratory devices. The project is part of GravNet , an ERC-funded network dedicated to optimizing the search for high-frequency gravitational waves using electromagnetic cavities and alternative experimental set-ups. The PhD researchers will contribute to the theoretical backbone of the initiative, with work s...

The University of the Basque Country (EHU) is inviting applications for up to three two-year postdoctoral positions in theoretical physics at the EHU Quantum Center and Department of Physics in Bilbao, Spain. The research environment includes early-Universe cosmology, observational cosmology and astrophysics, gravitation, and particle physics, including interdisciplinary interfaces among these areas. Positions are expected to start around September 2027 and are funded by the Basque Government. T...

The Theory Group at the Institut de Física d’Altes Energies (IFAE) is recruiting for two postdoctoral positions in theoretical particle physics and theoretical cosmology/gravitation, starting in Fall 2027. The appointments are based at the UAB Campus in Barcelona within IFAE’s Theory Division. IFAE is a public consortium attached to the Universitat Autònoma de Barcelona and works across theoretical, experimental, and technological high-energy physics. The selected researchers will join a theory ...

Several postdoctoral researchers will join the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) to work on holographic applications to cosmology and astrophysics , with a specific focus on gravitational waves . The project sits at the intersection of relativity and quantum mechanics , and will involve research on topics such as cosmological phase transitions, baryogenesis, neutron star mergers, spacetime singularities, and holography with dynamical boundary gravity.
