SAQFT: Algebraic quantum field theory for elementary and composite particles

Written by

Quantum field theory (QFT) was a crucial step in our understanding of the fundamental nature of the Universe. In its current form, however, it is poorly suited for describing composite particles, made up of multiple interacting elementary particles. Today, QFT for hadrons has been largely replaced with quantum chromodynamics, but this new framework still leaves many gaps in our understanding, […]

RadiaBeam: Safer X-ray sources with smaller particle accelerators

Written by

Many important technologies rely on the production of high-energy radiation, yet without the right precautions, the radioactive sources involved in these processes can be incredibly dangerous. Dr Sergey Kutsaev, together with a team at RadiaBeam Technologies, has now shown how these sources could be replaced by compact, low-cost, and flexible particle accelerators, capable of producing high-energy X-rays on demand. His […]

Thermodynamic modelling of dynamic cell phenotypes

Written by

The observed traits, or phenotypes, of living cell populations depend on complex networks of biological processes. How cells process information through those biochemical networks can be described by the mathematics of statistical thermodynamics. Through research at the National Institute of Standards and Technology (NIST), a multidisciplinary team has clearly shown how the physics of thermodynamics can enable an understanding of […]
