Abstract

摘要

In this talk, I will give a brief introduction to hyperbolic geometry at first. Then, the benefit to work with hyperbolic geometry and related new physics will be shown in detail. To be specific, I will, using 2D Bose gases, show that the dynamics of a SU(1,1) symmetric system can be visualized on the Poincare disc, and a SU(1,1) echo can be designed in such a system. Also, I will explain the Efimov-like states and the funneling effect on the Poincare half-plane at last.
