DESCRIPTION:Speaker: Marko Ljubotina\nhosted by Maksym Serbyn\nAbstract: I 
 will present an integrable Trotterization of the Heisenberg spin chain. Sp
 ecifically\, I will focus on the spin transport properties of the model wh
 ere one can observe diffusion\, superdiffusion and ballistic transport\, s
 imilar to what is seen in the continuous time case. I will initially prese
 nt numerical results for the model with a focus on the anomalous superdiff
 usive regime. After that\, I will switch focus to the ballistic regime whe
 re we have been able to obtain some analytical results. Curiously\, in thi
 s model ballistic transport also occurs in the easy-axis regime. I will th
 at this can be proven and derive a lower bound for the spin Drude weight\,
  which shows fractal behaviour and is expected to be saturated.
