The Theoretical Physics Program at CBPF brings together theoretical research areas that investigate systems generally characterized by relatively low interaction energies and a large number of particles. The central mission of theoretical physics is the understanding and formulation of models describing physical phenomena, based on scientific paradigms in statistical physics and complex systems, classical and quantum physics, atomic and molecular physics, fluid and plasma physics, condensed matter physics, mathematical physics, and optics.

Theoretical physics has increasingly become a fundamental driver of technological development and innovation. Experiments with significant technological potential are often grounded in physical models developed by researchers in these fields. For this reason, theoretical physics is widely recognized by developed nations as a strategic area for the advancement of science, leading to the establishment of numerous institutions dedicated to theoretical physics research worldwide.

In Brazil, theoretical physics has historically played a prominent role in the scientific community. The arrival of distinguished scientists such as Gleb Wataghin and Guido Beck during the first half of the twentieth century made a decisive contribution to the training of a generation of outstanding Brazilian physicists. Given the limited resources available for scientific research in Brazil until the 1970s, theoretical physics became the field that concentrated many of the country's internationally recognized physicists, largely because it required less investment in large-scale experimental infrastructure.

Theoretical physicists Jaime Tiomno, José Leite Lopes, and Francisco Mendes de Oliveira Castro were among the founders of CBPF. From its inception, they established a strong institutional tradition in theoretical physics, making CBPF a meeting point for internationally renowned researchers in the field. In 1962, when CBPF launched the first modern graduate program in physics in Brazil, its faculty consisted predominantly of theoretical physicists.

CBPF has consistently been home to theoretical physicists of national and international prominence. As a result, high-level research has been conducted in areas such as statistical physics, condensed matter physics, mathematical physics, quantum information, and field theory. Today, theoretical physics research increasingly relies on intensive computational simulations as an alternative to highly complex analytical calculations, requiring ever more powerful high-performance computing clusters.

Through the combined use of analytical and computational methods, researchers in the Theoretical Physics Program investigate a wide range of important problems at the frontiers of scientific knowledge, contributing to the advancement of fundamental science and its technological applications.
