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) ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to optimally simulate them on a computer? The answer comes from AI. Quantum field ...

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 ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...
