Event Details

Laser cooled trapped ions offer unprecedented control over both internal and external degrees of freedom at the single-particle level. They are considered among the foremost candidates for realizing quantum simulation and computation platforms that can outperform classical computers in specific tasks. In this talk I will show how linear arrays of trapped 171Yb+ ions can be used as a versatile platform for studying out-of-equilibrium many-body quantum systems. I will show how linear ion chains [1] enabled the recent observation of universal non-equilibrium spin dynamics after multiple quenches [2]. In this case the spin system exhibits different system size scalings of the spin fluctuations dynamics depending on the different initial states and on the number of quenches [3]. Finally, I will conclude outlining the prospects of my new experimental system at Rice aimed at the simulation of dissipative Floquet dynamics [4] and at the realization of higher order spin interactions for the simulation of lattice gauge theories [5].
