Quantum Time Crystals

Frank Wilczek

Abstract

Difficulties around the idea of spontaneous breaking of time translation symmetry in a closed quantum mechanical system are identified, and then overcome in a simple model. The possibility of ordering in imaginary time is also discussed.

    • Pfft. What if I conceive to build a perpetual motion machine, or conceive to disprove Special Relativity? First one, liquids with zero viscosity, such as helium superfluids. - http://www.sciencemag.org/content/286/5438/213.summary Or even 4 dimensional quantum time crystals…
