This article is the first part of a series about quantum field theory published by Quanta Magazine. Other stories in the series can be found here. Over the past century, quantum field theory has ...

Professor of Physics Tom Mehen died unexpectedly last weekend at age 54 at his home in Chapel Hill. The cause of his death has not been released. “Tom was a brilliant and ever-curious scientist — ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to optimally simulate them on a computer? The answer comes from AI. Quantum field ...

An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

At Aalto University in Finland, two physicists believe they may have cracked a puzzle that has defied generations of scientists: how to reconcile the physics of the very big with the physics of the ...

Peter Millington is a Senior Research Fellow in the Particle Theory Group at the University of Manchester, UK, where he holds a UK Research and Innovation Future Leaders Fellowship and a Royal Society ...

A lecture by the pioneer of Effective Field Theories (EFTs), Nobel Laureate Steven Weinberg, has been published. This introduces the concept of EFTs, their historical development and their application ...

Even in an incomplete state, quantum field theory is the most successful physical theory ever discovered. Nathan Seiberg, one of its leading architects, talks about the gaps in QFT and how ...

Every once in a while, a revolutionary idea comes along that has the potential to supersede our best scientific ideas of the day. This happened numerous times in theoretical physics during the 20th ...
