axions

Frank Wilczek has been at the forefront of theoretical physics for the past 50 years. He talks about winning the Nobel Prize for work he did as a student, his solution to the dark matter problem, and the God of a scientist.

Researchers say there are three possible explanations for the anomalous data. One is mundane. Two would revolutionize physics.

In a new paper, physicists argue that hypothetical particles called axions could explain why the universe isn’t empty.

Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.

A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.

The two physicists who introduced Peccei-Quinn symmetry came up with their idea on and around Stanford University’s campus 40 years ago.

The theoretical particle physicist Helen Quinn has blazed a singular path from the early days of the Standard Model to the latest overhaul of science education in the United States.

The physicist Asimina Arvanitaki is thinking up ways to search gravitational wave data for evidence of dark matter particles orbiting black holes.

The irreversibility of time may be a clue as to what makes up the universe’s dark matter.
