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.

None of us were consulted when the universe was created. And yet it is tempting to ask not only how the universe evolves, but also why, and could it be different? Our universe weighs more than 1050 tons. Could it be created “on the cheap”? Would it require a...

Many mathematical concepts trace their origins to everyday experience, from astronomy to mechanics. Remarkably, ideas from quantum theory turn out to carry tremendous mathematical power too, even though we have little intuition dealing with elementary particles. The bizarre quantum world not only...
