Offer Description

The present contract is funded by the Community of Madrid within the framework of the 2025 Call for grants aimed at Attracting Research Talent, César Nombela. File number: 2025-T1/COM-36104.

The hired researcher will use high-performance computing (HPC) techniques to simulate the early universe in the context of various high-energy physics theories of interest. In particular, they will study the formation of domain walls and other topological defects. They will also study the production of primordial gravitational waves by these phenomena and their possible detection by present or future experiments.

The duration of the contract is 4 months starting on mid December 2026.

Tasks to be carried out:

• Simulation of scalar field models at HPC centers (such as the C3 computing center at UC3M or others) with the code CosmoLattice.
• Analysis and physical interpretation of the results obtained from the simulations.
• Writing scientific articles for publication in high-impact scientific journals.
• Collaboration with researchers working with the project’s principal investigator (PI).
• Collaboration in the organization of seminars, workshops, and other specialized events.
• Delivery of talks at scientific conferences and seminars at other research centers.

Merits to be assessed:

• Master's degree in particle physics and/or cosmology, preferably with courses related to the early universe (compulsory).
• Experience in the use of “lattice” simulation codes for the early universe, such as CosmoLattice or similar (compulsory).
• Proven experience in cosmology and/or particle physics (e.g., a master’s thesis on the subject).
