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 rolling in ...

Generalized functions, often formulated as distributions, have become indispensable in the rigorous mathematical formulation of quantum field theory (QFT). These constructs extend the classical notion ...

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. This ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you wanted to answer the question of what's truly fundamental in ...

For centuries, the concept of consciousness has intrigued philosophers and scientists alike. Often deemed too abstract for ...

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

WEST LAFAYETTE, Ind.—Renowned French scientist Alain Aspect, who won the 2022 Nobel Prize for his pathfinding research in quantum physics, will give a lecture on Monday (May 13) at Purdue University ...

Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside. “That’s a super hard problem. It’s amazing they were able to,” said Dan ...

At the subatomic level, particles interact not only with one another, but with the quantum fields inherent to space, both owing to the presence of charged sources and also to the quantum vacuum of ...

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 ...

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