Dynamical development of long-range spatial coherence in non-equilibrium bosonic condensation
Bianca Rae Fabricante, Dąbrówka Biegańska, Paolo Comaron +14
Development of spontaneous coherence is one of the hallmarks of bosonic condensation in a variety of physical systems, such as cold atoms, confined photons, and hybrid light-matter…
