What is theoretical physics?

Theoretical physics is a branch of physics that uses mathematical models and abstractions to explain and predict natural phenomena. Unlike experimental physics, which focuses on observing physical processes, theoretical physicists develop theories and equations to understand how the universe works. Their work often involves formulating new ideas, such as quantum mechanics or relativity, and testing these concepts through logical reasoning and mathematical analysis. Theoretical physics plays a crucial role in advancing our fundamental knowledge and can also lead to practical applications in technology and engineering.

What are the qualifications to get a job in theoretical physics?

The qualifications that you need to get a job in theoretical physics include a degree in physics, mathematical skills, and, at an academic institution, teaching abilities. Some employers expect theoretical physics professionals to have at least a master’s degree in physics, and many prefer or require that applicants have or are in the process of obtaining a Ph.D. in theoretical physics. Most postgraduate programs seek students who have a bachelor's degree in physics or a closely related physical science.

What are the key skills and qualifications needed to thrive as a theoretical physicist, and why are they important?

To thrive as a Theoretical Physicist, you need advanced knowledge in mathematics, physics, and scientific research, usually demonstrated by a Ph.D. in physics or a related field. Mastery of mathematical modeling software, computer programming (such as Python or MATLAB), and familiarity with scientific publication tools are commonly required. Exceptional analytical thinking, problem-solving, and the ability to communicate complex ideas clearly help distinguish top performers in this field. These skills are crucial for developing new theories, contributing to scientific knowledge, and collaborating effectively within the global research community.

What are some common challenges faced by theoretical physicists when working on collaborative research projects?

Theoretical physicists often collaborate with researchers from diverse backgrounds, including experimentalists and computational scientists. One common challenge is effectively communicating complex mathematical concepts to team members who may not share the same theoretical expertise. Additionally, aligning different research approaches and timelines can be difficult, requiring flexibility and strong project management skills. Building consensus on research directions and integrating various perspectives is essential for successful collaboration in theoretical physics.

What is the difference between Theoretical Physics vs Experimental Physics?

AspectTheoretical PhysicsExperimental Physics
Required CredentialsAdvanced degrees in physics, often PhDSimilar degrees, often with additional laboratory training
Work EnvironmentTheoretical labs, offices, computer simulationsLaboratories, research facilities, experimental setups
Industry UsageResearch institutions, academia, government labsResearch institutions, industry R&D, academia
Common Search/ComparisonOften compared for research focus and skillsRelated but more hands-on and experimental

While both roles require advanced physics knowledge, Theoretical Physics focuses on developing models and simulations, whereas Experimental Physics involves conducting physical experiments to test theories. Both careers are integral to advancing physics but differ in approach and work environment.

Do theoretical physicists get paid well?

Theoretical physicists' salaries vary depending on experience, location, and employer, but they generally earn competitive wages, especially in academia, research institutions, and industry roles that require advanced degrees and specialized skills. Entry-level positions may pay less, while experienced physicists working in private sector research or with government agencies tend to earn higher salaries.

What can I do with a theoretical physics degree?

A theoretical physics degree prepares individuals for careers in research, academia, data analysis, and scientific consulting. Graduates often work in universities, government labs, or private industry, applying skills in mathematical modeling, problem-solving, and programming. Additional qualifications like a Ph.D. can expand opportunities in advanced research and teaching roles.

What jobs are there for theoretical physicists?

Theoretical physicists can work in academia as university professors or researchers, in government laboratories conducting fundamental research, or in industry roles such as data analysis, software development, and technology consulting. They often utilize strong analytical, mathematical, and programming skills, and may need advanced degrees like a Ph.D. to qualify for research positions.

Key responsibilities

  • Spark interdisciplinary collaborations across physics and AI domains to generate new ideas and approaches.

  • Work with two IAIFI mentors from Physics and AI to select research topics and evaluate research progress.

  • Identify and engage with IAIFI faculty members aligned with research goals.

Job description

The NSF Institute for Artificial Intelligence and Fundamental Interactions (IAIFI, pronounced /aɪ-faɪ/) is one of the inaugural NSF AI research institutes. The IAIFI is enabling physics discoveries and advancing foundational AI through the development of novel AI approaches that incorporate first principles, best practices, and domain knowledge from fundamental physics. AI is transforming many aspects of society, including the ways that scientists are pursuing groundbreaking discoveries.

To facilitate these advances, the IAIFI seeks a talented and interdisciplinary group of researchers at an early stage of their careers to join the IAIFI Fellowship program. The role of an IAIFI Fellow is to spark vital interdisciplinary, multi-investigator, multi-subfield collaborations across some of the primary IAIFI domains of theoretical physics, experimental physics, astrophysics, and foundational AI. Such collaborations have immense power to generate new ideas and approaches in both physics and AI, to facilitate abstracting physics challenges beyond their native domains to inform the development of cutting-edge AI tools, and to instill a common language across disciplines.

Our program aims to appoint new IAIFI Postdoctoral Fellows each academic year for three-year fellowship terms, contingent upon programmatic need and the availability of funding. In addition to the IAIFI Fellowships, related postdoctoral opportunities may be available with IAIFI faculty. Applicants may opt in to have their application materials shared with IAIFI faculty for consideration for these positions.

Fellows will be selected through an annual application process. Applicants should have, or be expected to receive by the 1st of September 2027, a PhD in Physics, Astrophysics, Statistics, Computer Science, or a related field. Complete applications must include:

  • Cover letter (no more than 1 page);
  • CV (1-2 pages recommended, but longer accepted);
  • Statement of research interests (no more than 2 pages);
  • List of publications;
  • Exactly three reference letters.

The deadline to receive all the materials (including all reference letters) is the 7th of October 2026.

The Fellows will have substantial freedom in choosing their research focus; each fellow will work with two IAIFI mentors – one from Physics and one from AI – to guide their choice of research topic and evaluate their research progress. Part of the application will include identifying IAIFI faculty whom you feel would be a good match for your research goals. The IAIFI is committed to building a vibrant intellectual community, and strongly encourages applications from interested researchers, regardless of background.
