Outline of Final Research Achievements

We have studied the decay process of a low dimensional superfluid stabilized by effective dimension engineering after quantum quench, and the many-body effects in transport phenomena of a correlated fermion system with energy dissipation. Also, we have proposed a realization scheme of a recently proposed model, which exhibits a non-Fermi liquid state related to the cuprate high-temperature superconductivity, in ultracold gas, and studied the relation of this model to other phenomena such as quantum gravity. Moreover we have numerically studied the breakdown of quantization in topological pumping due to many-body effects and clarified the relation to an effective model.
