报告摘要

The effective low energy interactions between ultracold atoms can be manipulated and controlled with high degree of accuracy by means of several experimental techniques. External confinement and fields can be used to drive the system from weakly to strongly interacting and viceversa. In particular, two body interactions can be engineered to be negligible at low energies. The naive expectation that the quasi-one-dimensional many-body problem, in such case, becomes non-interacting, will be analysed. In particular, the most important contribution to the physics of three or more bosons is a three-body interaction. I will review its emergence, its effects and potential experimental observation of genuine three-body effects in one dimension. 

个人简介

Manuel Valiente received a Marie Curie fellowship in 2007 to do his PhD at the Humboldt University in Berlin, Germany, where he obtained his PhD in 2010. He then receiveda Villum Kann Rasmussen postdoctoral fellowship at Aarhus University in Denmark, where heworked from 2010-2012. He was a senior Research Associate at Heriot-Watt University inEdinburgh, United Kingdom from 2012 to 2018. In 2018 he moved to the Institute for AdvancedStudy, Tsinghua University, where he is now an Associate Member.
