Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in ...

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

Twenty-five years ago this month, a conjecture shook the world of theoretical physics. It had the aura of revelation. “At first, we had a magical statement ... almost out of nowhere,” says Mark Van ...

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 ...

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 structures.

An international team of researchers has found a simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. An ...

Quantum researchers in the twenty-first century are part of an international network that requires a great deal of ...

Physicists have developed a novel approach to solving one of the most persistent problems in theoretical physics: uniting gravity with the quantum world. In a recent paper published in the journal ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

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.
