Title: Universal Landau-Zener regimes in dynamical topological phase transitions
Abstract: Topological quantum matters display fascinating response properties and robust edge states that put them at the center of continuous research. Generation, control and manipulation of topological matter proves to be a colorful theoretical playground and has become attainable in ultracold atom and condensed matter platforms in recent years. In this talk, I will discuss the dynamical preparation of the topological state of Floquet Chern insulators. I will show how a no-go theorem forbids transition between difference Chern insulator phases under unitary dynamics. In finite size systems, however, a topological phase transition can occur dynamically. Of the three regimes that the dynamics across these phase transitions falls into, we found that a universal Landau-Zener regime governs the behavior of dynamical topological phase transitions.
