The force due to gravity reduces with the square of the distance. If you double the distance, the force is not halved but reduced to a quarter of its original value. This law, called an inverse-square law, is based purely on geometry: we live in three spatial dimensions, and therefore the inverse-square law holds. However, if the universe has more than three spatial dimensions, the inverse-square law would break. UW physicists J. G. Lee, E. G. Adelberger, T. S. Cook, S. M. Fleischer, and B. R.... Read more

Neutrino Mass
December 5, 2019
Read more of an article from the American Physical Society that overviews the neutrino mass programs. It references work in which the UW was/is a major player; SNO Project (Nobel prize 2015), the KATRIN project (current mass limits - see PRL) and Project 8 (the next generation neutrino mass experiment, currently residing in Physics-Astronomy Building basement).

Electrons in atoms are pretty talented. They can form chemical bonds, get kicked out of the atom and even “jump” to different locations based on their energetic states.In 1961, atomic physicist Ugo Fano theorized that electrons harbor another and unexpected talent: They can interfere with themselves as they simultaneously take two different quantum-mechanical paths. On one path, they jump within the atom between discrete energy states. On the other path, they jump off the atom into the... Read more

A team led by scientists at the University of Washington has designed and tested a 3D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published Oct. 4 in the journal Science Advances, their designed optical element focuses light to discrete points in a 3D helical pattern. The team’s design principles and experimental findings... Read more

At the 2019 Topics in Astroparticle and Underground Physics conference in Toyama, Japan, leaders from the KATRIN experiment reported on Friday that the estimated range for the rest mass of the neutrino is no larger than 1 electron volt, or eV. These inaugural results obtained earlier this year by the Karlsruhe Tritium Neutrino experiment — or KATRIN — cut the mass range for the neutrino by more than half by lowering the upper limit of the neutrino’s mass from 2 eV to 1 eV.The University of...
