标题： Quantum droplets in a beyond-mean-field density-dependent gauge theory

摘要： 推导了适用于经历密度相关规范势的玻色多体系统的超出平均场修正，并由此探讨了量子液滴解的维度层次结构。单个相互作用参数（表征规范势的强度）支持非定态量子液滴解，而在一维情况下，超出平均场理论可以精确求解，从而得到手征量子液滴和暗孤子激发。手征液滴单个或成对的数值模拟表明，在超出平均场区域存在丰富的动力学行为。 显示英文摘要

摘要： The beyond-mean-field corrections appropriate to a bosonic many-body system experiencing a density-dependent gauge potential are derived, and from this the dimensional hierarchy of quantum droplet solutions are explored. Non-stationary quantum droplet solutions are supported by a single interaction parameter characterising the strength of the gauge potential, while in one dimension the beyond-mean-field theory can be solved exactly to yield chiral quantum droplets and dark soliton-like excitations. Numerical simulations of single and pairs of chiral droplets indicate a rich dynamics in the beyond-mean-field regime.
