Unlike perturbation theory, matrix models can be numerically simulated on computers, getting around some of the notorious difficulty of string-theory calculations. Although the matrices would have to ...

For specific applications of the L-function they describe, they found that their results correspond to another specific result from string theory.

Roughly speaking, he says, a mathematical formula that describes how the guitar string vibrates is what a string-theory formula would look like. The theory had immediate appeal.

String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...

String theory — equations that aspire to explain all of nature’s particles and forces — has extended its reach to the strange quantum behavior known as entanglement, physicists report ...

Elegance is a term theorists apply to formulas, like E=mc 2, which are simple and symmetrical yet have great scope and power. The concept has become so associated with string theory that Nova ’s ...

Roughly speaking, he says, a mathematical formula that describes how the guitar string vibrates is what a string-theory formula would look like. The theory had immediate appeal.

In a quantum theory of point particles, a fundamental quantity is the correlation function, which measures the probability for a particle to propagate from one point to another.

The conventional method to validate string field theory, is by use of quantum mechanics. However, the researchers worked backwards, using string field theory to validate quantum mechanics.

String theory: The good, the bad, the energy-hungry For decades, physicists have sought a unified theory that can reconcile quantum mechanics, and by extension, the behavior of subatomic particles ...
