The B factories, BESIII, and LHCb continue to discover new heavy mesons. The experimental status and possible theoretical interpretations of these states are discussed.

In the first part of this talk, I will discuss the application of non-equilibrium dynamics to a system of 1D bosons in an electric field which has been experimentally realized recently with emphasis on possible experimental signatures of dynamics in this system. In the second part, I shall briefly present a perturbative renormalization group approach to driven quantum field theories, show that a drive may lead to realization of non-gaussian, i.e. interaction driven, regimes for such systems, and discuss the implications of this result for dynamical phase transitions.

We consider quantum quench by a time dependent double trace coupling in a strongly coupled large N field theory which has a gravity dual via the AdS/CFT correspondence. We study the scalar dynamics in the probe approximation in two backgrounds: AdS soliton and AdS black brane. In either case we find that in equilibrium there is a critical phase transition. For a slowly varying homogeneous time dependent coupling crossing the critical point, we show that the dynamics in the critical region is dominated by a single mode of the bulk field. This mode satisfies a Landau-Ginsburg equation with a time dependent mass, and leads to Kibble Zurek type scaling behavior. For the AdS soliton the system is non-dissipative and has z=1, while for the black brane one has dissipative z=2 dynamics. These analytical results are supported by direct numerical solutions.

Abstract: The Minimal Model Holography, relating 3d higher spin gravity on AdS to 2d W_N minimal models will be reviewed in this talk. In particular, explicit black hole solutions carrying higher spin charges are constructed with proper thermodynamics. We compute the free energy of a charged black hole from the holographic dual at large central charge, and find exact match with the bulk thermodynamics. Furthermore, scalar fields propagating on the higher spin black hole backgrounds are studied. Explicitly, the higher spin corrections to the scalar two-point functions are computed from both the AdS side and the CFT side. Again, a perfect match is found, which gives further support to the minimal model holography.
