Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

Research The quantum and gravitational theory group works on a wide range of topics in theoretical physics, from string theory to quantum information, condensed matter, and cosmology. Faculty Research ...

String theory, like quantum theory, is background dependent in that it relies on the existence of time and space. Strings vibrate in space over time and string theory does not describe what time ...

The theory failed to unite gravity and quantum mechanics. But it still has become one of the most useful tools in science.

Researchers at The University of South Carolina, USC, have proposed that a link between string field theory and quantum mechanics does exist. The link assumes that string field theory is a fully ...

We give a brief survey of the attempts to understand the quantum dynamics of general relativity through the lens of quantum field theory, which has been successfully applied to the other fundamental ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

Two USC researchers have proposed a link between string field theory and quantum mechanics that could open the door to using string field theory — or a broader version of it, called M-theory ...

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the Large Hadron Collider.
