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 ...

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.

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.

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 ...

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 ...

The resulting theoretical developments brought about modern quantum field theory, and the interactions with virtual particles — the modern way to quantify the effects of “the radiation field ...

"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.

Many atomic nuclei have a magnetic field similar to that of Earth. However, directly at the surface of a heavy nucleus such as lead or bismuth, it is trillions of times stronger than Earth's field ...

Bianconi’s work extends this thermodynamic analogy, employing quantum relative entropy to bridge the gap between quantum field theory and general relativity.

Watch the most terrifying and mind-bending aspects of quantum theory, one that scientists are hesitant to discuss: the ...

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.
