Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory.

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

Brian Greene, a professor of physics and mathematics at Columbia University and director of Columbia’s Center for Theoretical Physics, is the author of “The Elegant Universe” and “Until the End of ...

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

From growing up in a Kolkata shaped by legends like Satyendra Nath Bose to winning the $3 million Breakthrough Prize, ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...
