Sigma models are a class of field theories where the fundamental fields constitute maps from a spacetime manifold to a target space endowed with rich geometric structures. These models have been ...

The study of Dirac-harmonic maps sits at the intersection of differential geometry and quantum field theory, uniting concepts from harmonic maps and spinor fields into a single elegant framework.

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

String theory might be the theory of everything… or a flawed framework for theoretical physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

The physicist Subir Sachdev borrows tools from string theory to understand the puzzling behavior of superconductors. String theory was devised as a way to unite the laws of quantum mechanics with ...
