Dealing with diminishing returns in quantum perturbations
Perturbations to quantum field theory are valuable tools for physicists as they approximate the properties of complex systems. However, limits in available computing power mean that the capabilities of their calculations are inherently limited. Recently, in a U.S. American-French-Italian collaboration, novel mathematical techniques have been used to circumvent this problem. The team’s approach could soon lead to long-awaited solutions to […]

Interferometry with antimatter
For nearly a century, physicists have struggled to understand why the universe contains so much more matter than antimatter. In a new experiment, Dr Marco Giammarchi and colleagues at the QUPLAS collaboration have demonstrated a technique which could help in their search for an answer. For the first time, the team have demonstrated interferometry with a single antiparticle – an […]
