| Outline of Final Research Achievements |
In this project, we have studied multicomponent quantum condensate as a non-equilibrium system and studied on time evolution, fluctuations and order formation of a non-equilibrium structure appearing in it, with close collaboration of theory and experiment.We also collaborated with other researchers in the project and aimed to elucidate universal phenomena appearing in multicomponent Bose-Einstein condensate. The collaboration realized by this project is very fruitful, and we were able to get many interesting results such as spatial structure formation by magnetic dipole interaction, influence of miscibility on non-equilibrium dynamics, novel behavior of spinor BEC mixture, magnon excitation, spin-orbit interaction, and universal critical behavior at a phase transition to quantum turbulence.
