Federico Nardelli Recent research led by the University of Trento reveals that fundamental atomic vibrations remain unchanged also in ultra-stable glasses. This discovery advances the decade-long debate on the physics of disorder and opens the way to new applications, from electronics to pharmaceuticals. The research work was carried out by the Department of Physics in collaboration with other European research institutions and published in Physical Review X . We are used to thinking of glass as a fragile and common material, but glass is still one of the greatest enigmas for physics. In crystals, atoms are arranged in geometric order, while chaos reigns in glass. This disorder generates unique properties, especially near absolute zero, where the glass behaves very differently from crystals.…
