Our paper on the emergence of coherence far from equilibrium was published in PRL (PRL 115, 175301) and has an accompanying viewpoint in Physics.
Long-range coherence is typically restricted to equilibrium situations at low temperatures. Here we have, in stark contrast, for the first time managed to observe the dynamic emergence of coherence in a system far from equilibrium following a strong quantum quench. Furthermore, the emerging order is different from the ground-state one and cannot be found in the equilibrium phase diagram.
