Adding up Feynman diagrams to make predictions about real materials
Illustration of a polaron in a crystal: the central bright sphere is the charge carrier, distorting the surrounding lattice. The wavy lines represent high-order Feynman diagrams for the electron–phonon interaction,…
Carefully tuned laser beam protects quantum spins from noise
Relaxation of alkali-metal spins and light-shift compensation. Credit: Avraham Berrebi et al Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing…
Speed test of ‘tunneling’ electrons challenges alternative interpretation of quantum mechanics
Experimental setup for measuring the speed of particles. Credit: Nature (2025). DOI: 10.1038/s41586-025-09099-4 Both interpretations make many of the same predictions, but they differ greatly in the way they describe…
‘Standard Candle’ Particle Measurement Enables Hunt for Hybrid Mesons
BYLINE: Matt Cahill Newswise — NEWPORT NEWS, VA – A rather unassuming particle is playing an important role in the hunt for subatomic oddities. Similar to protons and neutrons, mesons…
State-dependent values emerge from Dirac equation
