Adding up Feynman diagrams to make predictions about real materials
Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already enabled the researchers to solve a longstanding problem in the materials science and physics worlds known as the polaron problem, giving scientists and engineers
Speed test of ‘tunneling’ electrons challenges alternative interpretation of quantum mechanics
Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger’s cat analogy, and ability to slip through barriers, a phenomenon known as quantum tunneling.Quantum Physics NewsRead More
