Reconfigurable single-atom array for Rydberg atom quantum simulation
Abstract: Recently realized single-atom array synthesizers have drawn much attention because defect-free single-atom array suitable for spin-lattice quantum simulation can be quickly formed . Subsequently, their capabilities as Rydberg quantum simulators have been demonstrated as well . In this talk, I will introduce our results on the array synthesizer and proof-of-principle quantum simulation thereof:
1) In the first part, I will report on how defect-free single-atom array could be prepared by using a liquid-crystal spatial light modulator. Further performance improvement for speed, scale, and dimension will be discussed as well.
2) In the second part, an experimental result on thermalization dynamics of Ising-like spin-1/2 chain will be presented; the microscopic principle of the thermalization (detailed balance between spin-flip) was observed. It is worth noting that this thermalization scenario is a natural consequence of mere Schroedinger equation, rather than a result of an assumption such as connection to a thermal bath. Also, I will discuss about extending the thermalization scenario to a larger chain and higher dimensions.
