Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

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 ...

An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

MODERN physics has two stories to tell about our universe. The first says it is fundamentally made of space-time: a continuous, stretchy fabric that has ballooned since the dawn of time. The other ...

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.

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...
