Query: Dynamical Singularities of Glassy Systems in a Quantum Quench   We present a prototype of behavior of glassy systems driven by quantum
dynamics in a quenching protocol by analyzing the random energy model in a
transverse field. We calculate several types of dynamical quantum amplitude and
find a freezing transition at some critical time. The behavior is understood by
the partition-function zeros in the complex temperature plane. We discuss the
properties of the freezing phase as a dynamical chaotic phase, which are
contrasted to those of the spin-glass phase in the static system.
