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 […]

A biochemical device to demystify a century-old thermodynamics puzzle from theoretical physics
Maxwell’s demon and Szilard’s engine – thought experiments from the 19th and early 20th centuries – have long captured the imagination of theoretical physicists. Many still disagree about the interpretation of these ideas, the implications for the second law of thermodynamics and the consequences for thermodynamics of computation. Along with collaborators, Dr Thomas Ouldridge at Imperial College London has designed […]
