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 ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

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

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

The problem with quantum mechanics, or at least the reason even physicists don’t understand it, isn’t that it paints an unfamiliar picture of reality. It isn’t difficult to accept that the world of ...

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.
