Scientists from the Max Planck Institute for the Physics of Complex Systems have theoretically described a state called 'discrete time fluid', where ordered oscillations are maintained only over limited time intervals. The work is posted on arXiv and has not yet undergone peer review.
Aziz KarimovResearchers at the Chinese Academy of Sciences, using an ultrashort laser pulse on a tungsten needle, produced a glowing plasma ball that lived longer than the pulse that created it. The observations match the model of an electromagnetic soliton. The work, published in Nature Photonics, provides a controllable model for testing hypotheses about the nature of ball lightning, but is not considered an exact copy of the atmospheric phenomenon.
Otabek YusupovResearchers at the University of Amsterdam reported in Nature a 'time crystal' whose rhythm emerged without external periodic forcing — through a mechanism of 'wave coarsening'. The system was assembled from 37 metamaterial cells printed on a 3D printer; the synchronous rhythm persisted even with added noise.
