Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena.
May 15, 2024 · Theoretical physics is the development of mathematical formalisms and computational protocols for describing all aspects of objects found in the world around us and their interaction.
We are a unified research and teaching center focused on fundamental physics. Our activities range from string theory and cosmology at the highest energies down through unification and beyond-the-standard-model physics, through the standard model, to QCD, hadrons, quark matter, and nuclei at the low energy scale.
May 1, 2024 · Introduction to Theoretical Physics From First Principles to Classical Mechanics to General Relativity. Theoretical physics is the branch of physics that deals with developing and evolving theory to explain the fundamental nature of the universe.
Dec 22, 2023 · Quantum hypothesis testing—the task of distinguishing quantum states—enjoys surprisingly deep connections with the theory of entanglement. Recent findings have reopened the biggest questions ...
5 days ago · Stanford Institute for Theoretical Physics. Our research includes a strong focus on fundamental questions about the new physics underlying the Standard Models of particle physics, cosmology, and gravity; and the nature and applications of our basic frameworks (quantum field theory and string theory) for attacking these questions.
Quantum physics and Einstein’s theory of general relativity are the two solid pillars that underlie much of modern physics. Understanding how these two well-established theories are related remains a central open question in theoretical physics.
