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 ...

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

Generalized Functions and Quantum Field Theory Publication Trend The graph below shows the total number of publications each year in Generalized Functions and Quantum Field Theory.

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.

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 ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory ...

Nobel laureate Alain Aspect to give May 13 lecture at Purdue on pioneering efforts in quantum physics and technology WEST LAFAYETTE, Ind.—Renowned French scientist Alain Aspect, who won the 2022 Nobel ...

Recent progress on both analog and digital simulations of quantum fields foreshadows a future in which quantum computers ...

Quantum mechanics isn’t sufficient to explain the Universe; for that, quantum field theory is needed. This is why. Schematic animation of a continuous beam of light being dispersed by a prism.

"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.

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
