An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

This article, prepared in conjunction with AFCEA’s Technology Committee, is the second in a series of three articles addressing quantum computing. The inaugural article, "The Current State of Quantum ...

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 ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

In an effort to solve the riddle of why we have subjective conciousness, scientists have develop myriad theories, including ones involving the quantum realm. A new theory suggests that consciousness ...

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.

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Gravity, long the sovereign force in the cosmic hierarchy, may be little more than a statistical side effect a byproduct of entropy, not a fundamental interaction. That is the provocative assertion ...
