作为动力学三体相互作用的原子三体损耗
Atomic three-body loss as a dynamical three-body interaction
摘要：
我们讨论了光晶格中原子的大三体损耗如何引起有效的硬核三体相互作用。对于玻色子，除了通常的原子超流体，二聚体超流体可以观察到吸引的两体相互作用。通过结合含时密度矩阵重整化群技术和量子轨道方法，在一维中研究了这些相的制备和稳定性的非平衡动力学。
英文摘要：
We discuss how large three-body loss of atoms in an optical lattice can give rise to effective hard-core three-body interactions. For bosons, in addition to the usual atomic superfluid, a dimer superfluid can then be observed for attractive two-body interactions. The non-equilibrium dynamics of preparation and stability of these phases are studied in 1D by combining time-dependent Density Matrix Renormalisation Group techniques with a quantum trajectories method.
