Query: Quantum quench in matrix models: Dynamical phase transitions, Selective
  equilibration and the Generalized Gibbs Ensemble   Quantum quench dynamics is considered in a one dimensional unitary matrix
model with a single trace potential. This model is integrable and has been
studied in the context of non-critical string theory. We find dynamical phase
transitions, and study the role of the quantum critical point. In course of the
time evolutions, we find evidence of selective equilibration for a certain
class of observables. The equilibrium is governed by the Generalized Gibbs
Ensemble (GGE) and differs from the standard Gibbs ensemble. We compute the
production of entropy which is O(N) for large N matrices. An important feature
of the equilibration is the appearance of an energy cascade, reminiscent of the
Richardson cascade in turbulence, where we find flow of energy from initial
long wavelength modes to progressively shorter wavelength excitations. We
discuss possible implication of the equilibration and of GGE in string theories
and higher spin theories. In another related study, we compute time evolutions
in a double trace unitary matrix model, which arises as an effective theory of
D2 branes in IIA string theory in the confinement phase. We find similar
equilibrations and dynamical transitions in this matrix model. The dynamical
transitions are related to Gregory-Laflamme transitions in string theory and
are potentially connected with the issue of appearance of naked singularities.
