In quantum field theory, when a not-so-stable state transforms into the true stable state, it's called "false vacuum decay."

Quantum field theory has predicted that subregions of a system of many entangled particles can be assigned a temperature profile.

Conformal field theory acts as a bridge between different fields of physics: the underlying math is used in string theory, condensed matter physics and quantum statistical mechanics.

Tong ended up connecting the fluids on Earth to the quantum Hall effect again, but through a different approach, using the language of quantum field theory.

The trouble is that the predicted value for the cosmological constant from calculations using quantum field theory produces a number that is too large by a factor of 10120.
