Research Associate - Theory (Fermilab) Fermilab in United States

The Department of Physics at Arizona State University invites applications for a full-time Postdoctoral Research Scholar in the Targeted Simons Research Group on Cosmic Magnetism . The position is based on the Tempe campus and is part of a collaborative, multi-institutional team focused on all aspects of cosmic magnetic fields. The successful candidate will join a research environment that combines theoretical high-energy physics, cosmology, and astrophysics. The project centers on the generatio...

The University of Michigan’s High Energy Theory group in the Leinweber Institute for Theoretical Physics is inviting applications for a postdoctoral position starting in Fall 2027. The role is based in the Department of Physics within the High Energy Theory and Cosmology Groups in Ann Arbor. The position is broadly focused on theoretical and mathematical physics, with research areas spanning standard model physics, beyond-the-standard-model physics, astroparticle physics and cosmology, dark matt...

The International Centre for Theoretical Physics (ICTP) in Trieste is offering several postdoctoral positions in its High Energy, Cosmology and Astroparticle Physics (HECAP) section, with an expected start in October 2027. The research environment spans a broad range of theoretical and phenomenological topics, including string theory, black holes, gauge/string duality, particle phenomenology beyond the Standard Model, dark matter, axions, Higgs and collider physics, neutrino physics, astrophysic...

Northeastern University invites applications for a Postdoctoral Research Associate in the Blazek group at its Boston Main Campus. The group conducts research in cosmology using theoretical, observational, and numerical methods. The research environment includes analysis of data from the Dark Energy Survey (DES), as well as preparation for future observations with the Vera C. Rubin Observatory and the Nancy Grace Roman Space Telescope. The postdoctoral researcher will contribute to basic or appli...

QUP at KEK is recruiting postdoctoral fellows in theoretical physics. The positions are based in the International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (QUP), a World Premier International Research Center Initiative hosted by the High Energy Accelerator Research Organization (KEK) in Tsukuba, Japan. The fellows will carry out theoretical research in areas such as particle phenomenology, cosmology, astroparticle physics, neutrino physics, quantum ...
