The quantum field theory framework needed some adjustment for Borinsky and Vogtmann to get the right count. For instance, in quantum field theory, two graphs that are mirror images of each other are ...

Visualization of a quantum field theory calculation showing virtual particles in the quantum vacuum. (Specifically, for the strong interactions.) Even in empty space, this vacuum energy is non-zero.

People had new insights about entropy in quantum field theory — the whole story about “it from qubit.” The AdS/CFT duality connects a theory of gravity in a space-time region called anti-de Sitter ...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum ...

Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition?

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 ...

"A quantum theory of gravity is needed to understand what kind of phenomena there are in cases where there's a gravitational field and high energies," says Partanen.
