Gauge theory and string theory represent two foundational pillars in contemporary theoretical physics, offering profound insights into the nature of fundamental interactions and the structure of the ...

Researchers have used the coldest systems in the universe to realize in the laboratory gauge theories, key models of modern physics that describe the fundamental forces of Nature and the behavior of ...

Physicists have developed a new approach to couple quantized gauge fields to ultracold matter. The method might be the basis for a versatile platform to tackle problems ranging from condensed-matter ...

From Fundamental Concepts to Dynamical Mechanisms, by Wolfgang Bietenholz and Uwe-Jens Wiese, Cambridge University Press.

A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with quantum mechanics. Physicists Mikko Partanen and Jukka Tulkki at Aalto ...

“The main idea is to have a gravity gauge theory with a symmetry that is similar to the Standard Model symmetries, instead of basing the theory on the very different kind of spacetime symmetry of ...

Chen Ning Yang (Ph.D. ’48), a Nobel Prize–winning physicist whose research transformed understanding of how particles behaved ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...
