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.   Our research also includes a major emphasis on the novel phenomena in condensed matter physics that emerge in systems with many degrees of freedom.


Once upon a time, about 13.8 billion years ago, our universe sprang from a quantum speck, ballooning to one million trillion trillion trillion trillion trillion trillion times its initial volume (by some estimates) in less than a billionth of a trillionth of a trillionth of a second.

If a pebble is thrown into a black hole, an observer outside the black hole will see waves of energy diffuse outwards along the event horizon.

Professor Steven Kivelson of the Stanford Institute for Theoretical Physics (SITP) introduces the physics of supercondictivity and condensded matter physics. Superconductivity is perhaps the most spectacular macroscopic quantum phenomenon. A “persistent current” in a ring of...

In the last few decades, we have been able to look at the sky with unprecedented precision and our understanding of the evolution of the universe has changed radically.  We have found that the universe is very large and remarkably homogeneous, but at the same time it has structures on all...
The discovery of the Higgs particle at the Large Hadron Collider  in 2012 completes the Standard Model of particle physics, which successfully accounts for almost all phenomena observed in the universe.  Professor Savas Dimopoulos of the Stanford Institute for Theoretical Physics (SITP)...
