SIG Meeting: Chasing Tornadoes: Vorticity Above, Below, and in the Lab



Overview

Carlo Ferruccio Barenghi is one of the leading figures in the field of quantum fluids, where he has pioneered the application of ideas from modern fluid mechanics in this exotic, low-temperature, realm. His scientific career began at the University of Milan where he obtained a degree in theoretical physics. He subsequently moved to the US where he was awarded a Ph.D. in experimental physics at the University of Oregon, working with one of the true pioneers of the science of cold, Russ Donnelly. He moved to the UK in the early 1980s working with the father of quantum turbulence, Joe Vinen, in Birmingham. In 1986 Carlo moved to Newcastle, where he has remained for the past three decades. At Newcastle he has been responsible for establishing one of the world leading quantum fluids groups, and making numerous important breakthroughs in the field of quantum fluids. For all of Carlo’s abilities (and achievements) as a scientist it his infectious curiosity and entirely positive approach which have fired a passion for the cold and the "tangled" inside generations of scientists.

On the occasion of his 65th birthday, we have the pleasure of hosting a conference in Carlo's spirit, bringing together people belonging to the different scientific communities Carlo has worked in.

Venue and Directions

All talks for Chasing tornadoes: vorticity above, below, and in the lab will be located in the Herschel Building - home of the School of Mathematics, Statistics & Physics and within walking distance of Haymarket Metro station.

Most talks will be given in room LT3, with refreshments just outside the room on the Herschel Building's ground-floor concourse. Carlo Barenghi's lecture and Keith Moffatt's public lecture will both be given in room LT1.

The Herschel Building Penthouse is booked for the whole event. Lunches, the Monday buffet, and the poster session will be held there.
