Project A03 investigates long-range ordered crystalline, supersolid or magnetic states of interacting Rydberg gases in optical lattices, as well as their formation and melting dynamics, based on dynamical mean-field theory and variational wave functions. We will also study polaronic quasiparticles, their transport and interband dynamics in periodic lattice potentials, both for atomic impurities in Bose-Einstein condensates and in hybrid ultracold atom-ion systems. A further focus will be on the expansion and dynamical arrest of strongly correlated bosons after quantum quenches, and their adiabatic cooling in frustrated optical lattices.

项目A03研究光学晶格中相互作用的里德伯气体的长程有序晶体，超固体或磁性状态，以及它们的形成和熔化动力学，基于动态平均场理论和变分波函数。我们还将研究极化准粒子，他们的运输和带间动力学在周期性晶格势，无论是在玻色-爱因斯坦凝聚和混合超冷原子离子系统中的原子杂质。进一步的重点将放在量子猝灭后强关联玻色子的膨胀和动力学被捕，以及它们在阻挫光晶格中的绝热冷却。
