活动主题：mediated interaction between impurities in bose-einstein condensates
形式：线上会议报告
内容摘要：
mediated interaction plays a crucial role for our understanding of nature. they are central to landau’s widely used quasiparticle theory, and all interactions are mediated by gauge bosons at a fundamental level. in this talk, i will present our recent work on mediated interaction between impurities in bose-einstein condensates (becs). in the first part, i discuss the interaction between two trapped ions mediated by a surrounding quantum degenerate bose gas and show that the induced interaction leads to substantial and observable shifts in the ion phonon frequencies. in the second part, i discuss the interaction between mobile impurities immersed in a bec in a two-dimensional
square lattice and predict the formation of the bipolaron, which should be detectable using high resolution quantum gas microscopy in optical lattices.
