Face the unknown with a Nobel Prize Laureate in Physics

Even this year, the Gothenburg Physics Centre presents a public lecture with a Nobel Prize Laureate in Physics. On Thursday 26 September Prof. Frank Wilczek will visit Gothenburg and share new ideas in axion searches.
Frank Wilczek, born in 1951, is a theoretical physicist, author, and intellectual adventurer. He has received many prizes for his work, including the Nobel Prize in Physics in 2004, along with David Gross and H. David Politzer, for their discovery of asymptotic freedom in the theory of the strong interaction.
Frank Wilczek has made seminal contributions to fundamental particle physics, cosmology and the physics of materials. His current theoretical research includes work on Axions, Anyons, and Time Crystals. These are concepts in physics which he named and pioneered. Each has become a major focus of world-wide research.

At the lecture in Gothenburg, he will talk about axion searches. Axions are hypothetical elementary particles that could constitute part, or all, of the dark matter content of the universe.
Observations indicate that approximately 85 percent of the matter in the universe is dark, that is, interacts very weakly with light and ordinary matter. Only  the remaining fraction constitutes the ordinary baryonic matter that composes stars, planets, and  all we see around us.  The physical nature of dark matter is currently unknown, and there are a wide variety of possibilities. Among them are a new type of weakly interacting massive particle, primordial black holes, and axions.

Besides his ongoing research activities, Frank Wilczek is fascinated with prospects for expanding perception (especially color perception) through technology.  He is developing hardware and software tools for this. He has also authored several well-known books and writes a monthly "Wilczek's Universe" feature for the Wall Street Journal. On his homepage he also promises an upcoming murder mystery…

About the lecture:
The lecture by Professor Frank Wilczek will be open to the public, free of charge and held in Gustaf Dalén lecture hall at Chalmers campus Johanneberg, Gothenburg on 26 September 2019, 15.15-16.15. Coffee and cake will be served in the entrance hall of Gustaf Dalén Lecture hall (Chalmers tvärgata 4) from 14.45.
No registration is needed, but make sure to be in time to grab a seat.
The talk is part of the General Physics Colloquia series of the Gothenburg Physics Centre.

More about Professor Frank Wilczek:
Frank Wilczek received a B.S. at the University of Chicago in 1970, and a PhD in physics at Princeton University in 1974. Currently he is the Herman Feshbach professor of physics at the Massachusetts Institute of Technology (MIT), Founding Director of the T. D. Lee Institute and Chief Scientist at Wilczek Quantum Center, Shanghai Jiao Tong University; Distinguished Origins Professor at Arizona State University; and Professor at Stockholm University.

More about the Nobel Prize in Physics 2004:
The atomic nucleus is held together by a powerful, strong interaction that binds together the protons and neutrons that comprise the nucleus. The strong interaction also holds together the quarks that make up protons and neutrons. This interaction is so strong that no free quarks have ever been observed. However, in 1973 Frank Wilczek, David Gross, and David Politzer showed that that when quarks come really close to one another, the attraction abates and they almost behave like free particles. This is called asymptotic freedom and has been the cornerstone of applications of the theory of strong interactions to collider experiments such as the LHC.
