Centennial Conference "Crossing the Disciplinary Boundaries of Physics"

Many people from IND have been involved in the organization of this celebration of the centenaries of the Niels Bohr Institute (founded in 1921) and Niels Bohr’s Nobel Prize in Physics (awarded to him in 1922).

Extreme measuring device can bring quantum technology to your smartphone

University of Copenhagen researchers have invented a “quantum drum” that can measure pressure, a gas leak, heat, magnetism and a host of other things with extreme precision. It can even scan the shape of a single virus.…
