Inhomogeneous quantum phases and dynamics in ultracold gases and hybrid atom-ion systems (A03)

A03项目基于动力学平均场理论和变分波函数，研究了相互作用的里德堡气体在光学晶格中的长程有序结晶、超固态或磁态，以及它们的形成和熔化动力学。我们还将研究周期晶格势中的极化子准粒子、它们的输运和带间动力学，包括玻色-爱因斯坦凝聚体和混合超冷原子-离子系统中的原子杂质。进一步的焦点将集中在强关联玻色子在量子猝灭后的膨胀和动力学停止，以及它们在受挫光学晶格中的绝热冷却。

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.
