Norman Yao, a UC Berkeley assistant professor of physics, has also predicted what the various phases surrounding the time crystal should be akin to the liquid and gas phases of ice in a paper published online recently in the journal Physical Review Letters. While conventional crystals have an at...

Driven percolation and time crystals We have established that long-range correlated local densities \({\{{n}_{i,t}\}}_{i}\) give rise to a bistable phase. We now show how, in a driven DP with periodically modulated update rules, this phase intimately relates to the emergence of a cla...
Time crystals are many-body states that spontaneously break translation symmetry in time the way that ordinary crystals do in space. While experimental observations have confirmed the existence of discrete or continuous time crystals, these realizations

This is a review of the recent activity of a collaboration on the basis of an INTAS grant 'The luminescence process — a study of the excitation and radiation dynamics of materials using synchrotron radiation'. For the following crystals (CeF 3 , LaF 3 :Ce, PWO, LSO:Ce, CsI, RbI, KI...
Crystals are extraordinary objects, not least because of their symmetry. Crystals form repeating patterns that are the same in some directions but not all directions. That’s something of a surprise given that the laws of physics, which govern their form
