Frank Wilczek hosts first workshop on axions as professor at Stockholm University

December 05, 2016

Stockholm University and NORDITA host this week an international workshop on axions and dark matter. Axions are hypothetical particles proposed by Nobel Laureate Frank Wilczek who this year started his appointment as professor at Stockholm University.

Dr. Frank Wilczek shared the Nobel Prize in 2004 with David J. Gross and H. David Politzer for discovering the equations that describe the strong force that is responsible for holding atomic nuclei together. With a generous grant from the Swedish Research Council Frank Wilczek has started a joint appointment at Stockholm University and the Massachusetts Institute of Technology (MIT). Throughout his career Frank Wilczek has worked on a number of different problems in condensed matter physics, astrophysics, and particle physics, including proposing new particles.

Axions are hypothetical particles invented in the late 1970s to solve a major blemish of the standard model of particle physics, namely its failure to explain why the fundamental laws of physics look almost the same if you run time backwards. To address this issue Roberto Peccei and Helen Quinn postulated a new kind of symmetry, now called Peccei-Quinn (PQ) symmetry. Frank Wilczek and Steven Weinberg independently realized a key consequence of PQ symmetry, which its authors had overlooked: it implies the existence of a new particle that Wilczek named the axion, after a laundry detergent (since it removes a stain). If axions exist, they will not only solve a big problem in fundamental physics - they are also likely to supply the mysterious 'dark matter' observed by astronomers.

In recent years axions have inspired many new theoretical investigations, recorded in thousands of papers. Importantly, now the stage seems set for breakthroughs on the experimental front. Stockholm University and NORDITA (The Nordic Institute for Theoretical Physics) are hosting an international axion dark matter workshop in Stockholm, December 5-9, bringing together leading researchers in the field. Frank Wilczek is among the organizers of the workshop.

Frank Wilczek comments: "It's been a joy to see the ideas around axions grow in many directions, from their roots in fundamental physics to cosmology and even, recently, the description of interesting materials. But I'd love to see axions themselves move from virtual reality to augmented reality. I'm optimistic that we'll make that big step soon. The physics world is hungry for it, and we're mobilizing.''

What If?
There's plenty of speculation about what Donald Trump might do in the wake of the election. Would he dispute the results if he loses? Would he simply refuse to leave office, or even try to use the military to maintain control? Last summer, Rosa Brooks got together a team of experts and political operatives from both sides of the aisle to ask a slightly different question. Rather than arguing about whether he'd do those things, they dug into what exactly would happen if he did. Part war game part choose your own adventure, Rosa's Transition Integrity Project doesn't give us any predictions, and it isn't a referendum on Trump. Instead, it's a deeply illuminating stress test on our laws, our institutions, and on the commitment to democracy written into the constitution.
