Discovering new phenomena through the design and synthesis of new materials

A field-free supercurrent diode

Informal Group Discussion Topic

"The world's first nuclear meltdown occurred in Chalk River near Ottawa, Canada in 1952. The clean-up was done in part by future US president Jimmy Carter. Carter and many other volunteers had multiple 90-second radiation exposures, amounting to 1 year's worth of radiation each time!" - Chris Lygouras

IGD currently organized by: Gregory Bassen
