Quantum Theory

"Edward Witten has spent almost 50 years at the forefront of theoretical and mathematical physics. Here he describes how the LHC and other recent results have impacted his view on nature, and asks whether naturalness is still a useful guide for the field."

When particle physicists try to model experiments, they confront an impossible calculation — an infinitely long equation that lies beyond the reach of modern mathematics. But three recent papers from a group of physicists led by Sebastian Mizera...

Stephen Adler, Professor Emeritus in the School of Natural Sciences, spoke to science writers contributing to Scientific American and New Scientist about testing models that seek to explain quantum measurement by subtly modifying quantum mechanics–...

Approximately 166 graduate students and postdoctoral scholars from 76 different institutions, representing 21 countries, will participate in “From Qubits to Spacetime,” the theme of Prospects in Theoretical Physics (PiTP) 2018, an intensive two-week...

Scott Aaronson, former Member in the School of Mathematics, discusses the capabilities and limits of quantum computers, common misconceptions, and fundamental science with Craig Cannon of Y Combinator.

Nima Arkani-Hamed, Professor in the School of Natural Sciences, delivered the public lecture “The End of Spacetime” at SLAC National Accelerator Laboratory in Menlo Park, CA, on June 19.

Watch Arkani-Hamed discuss the union of quantum mechanics and...

Philip Perry of Big Think asks, "What's our position in the universe?" Referencing the work of Juan Maldacena, Carl P. Feinberg Professor in the School of Natural Sciences, and former Members in the School Daniel Louis Jafferis, Leonard Susskind...

Professor Nathan Seiberg sat down with Sandhya Ramesh at an event organised by the International Centre for Theoretical Sciences for an interview for the Wire to discuss string theory, experimental evidence, quantum field theory, and more.

“When you have dualities, things that are easy to see in one description can be hard to see in the other description. So you and I, for example, are fairly simple to describe in the usual approach to physics as developed by Newton and his successors...

Reductionism breaks the world into elementary building blocks. Emergence finds the simple laws that arise out of complexity. Robbert Dijkgraaf, Director and Leon Levy Professor, explores how these two complementary ways of viewing the universe come together in modern theories of quantum gravity.
