Abstract: 

Understanding quantum many-body systems can be hard, especially when dealing with large systems. To understand these systems, Feynman proposed the concept of universal quantum simulator (i.e. quantum computer) in 1982; however, until today, full-scale quantum computers are still not present. With universal quantum simulators unavailable, another idea is proposed: using a well-controlled quantum system to simulate another less controllable or less accessible quantum system. This is quantum simulation. Ultracold atoms offer unique features to simulate quantum many-body systems. The advantages of such systems are the extreme controllability and tunability. I propose using a quantum mixture of lithium (Li) and cesium (Cs) atoms to simulate many-body systems. In my group at NTHU, we will first use the mixture to simulate disordered many-body systems. In this talk, I will talk about our plan moving towards this goal. In the end, I will also discuss possible extensions of our system to other many-body problems.
