According to the recent review by Krzysztof Sacha and Jakub Zakrzewski “Time crystals are time-periodic self-organized structures postulated by Frank Wilczek in 2012”. In my talk I will describe a relativistic realization of this concept in the system made of electron-positron pairs and the electromagnetic field. The only departure from full-fledged QED is the use of the mean field approximation in the treatment of the electromagnetic field.
