Dynamical phase transitions, caustics, and quantum dark bands

Dynamical phase transitions, caustics, and quantum dark bands

We provide a new perspective on quantum dynamical phase transitions (DPTs) by explaining their origin in terms of caustics that form in the Fock space representation of the many-body state over time, using the fully connected transverse field Ising model as an example. In this way we establish a con...
