Job profile

The candidate will explore the application of ultrashort structured pulses in ultrafast magnetism, an emerging field that is opening exciting scenarios in laser-matter interaction at the most fundamental level, merging the fields of Optics and Magnetism. The candidate will count not only with the collaboration of the theory research team at ALF-USAL (Dr. Luis Plaja, Dr. Julio San Román, Dr. Enrique Conejero and Dr. Carlos Hernández-García), but also with the collaboration of the research group on simulation of magnetic nanostructures SINAMAG at USAL, in particular with Prof. Luis López-Díaz and Dr. Rocío Yanes.

Successful candidates will have the possibility to consolidate their own independent research lines and to promote collaborative research among the following research lines:

  • Development of theoretical simulations of strong-field laser-matter interactions.
  • Development of theoretical models to describe the interaction of ultrafast structured laser pulses with gases and solids.
  • Implementation of high-performance computing simulations of strong-field laser-matter interaction.
  • Theoretical study of the ultrafast generation of magnetic textures (such as skyrmionic structures or vortices) using structured laser pulses.
Job Functions
  • To develop and implement theoretical models of laser-matter interaction along the described research lines.
  • To conduct independent research as well as in collaboration with other members of the group.
  • Co-advise undergraduate and Master students at University of Salamanca.
Candidate Requirements


  • Ph.D. in Physics, Chemistry or related Engineering degree, at the date of recruitment, with experience in theoretical Atomic, Molecular and Optical Physics, Photonics, Magnetism and/or Condensed matter physics.
  • Advanced skills in developing and implementing theoretical simulations of strong field laser-matter interaction, ultrafast magnetism and/or condensed matter physics.
  •  Demonstrable team working skills.
  • Advanced level of English.
  • Candidates should be able to demonstrate a promising track record of achievements appropriate to their research field and career stage. CVs will be evaluated taking into account the overall track record of the researcher in relation to their level of experience.
Contract conditions
  • Dynamic and international working environment.
  • Training and access to a wide range of scientific facilities.
  • Soft skills training.
  • Employment conditions:
      • Two-years full-time employment contract.
      • Gross salary of 2.750 €/month.
      • Starting date: September 2023.
  • Research Project: ATTOSTRUCTURA, “Structured attosecond pulses for ultrafast nanoscience”, funded by the European Research Council (ERC)
  • Workplace: Laser Applications and Photonics Research group (ALF-USAL) at University of Salamanca (, Spain.

Interested candidates should send a CV (maximum 4 pages), a personal statement with interests and reasons for applying, and two recommendation letters to Dr. Carlos Hernández-García at
