AdS/CFT suggests that our three-dimensional universe can be modeled by a two-dimensional surface. AdS (Anti-de Sitter space) ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

The worldline formalism presents an elegant and computationally efficient approach to quantum field theory, recasting field interactions in terms of first-quantised particle paths. By utilising path ...

Noncommutative Quantum Field Theory represents an ambitious extension of standard quantum field theory that incorporates a fundamental noncommutativity in the structure of spacetime. In these models, ...
