Quantum Fields and Strings

Quantum field theory is used to describe the interactions of elementary particles, the dynamics of many-body systems, and critical phenomena, all with exquisite accuracy. String theory is based on the idea that, at very short distances, all particles should be seen to be extended one-dimensional objects: “strings.” Together, “quantum fields and strings” has strong connections to condensed matter, quantum gravity, particle physics, and cosmology, and mathematics.
