The Poisson -model is a 2-dimensional sigma-model quantum field theory whose target space is a Poisson Lie algebroid. It is a 2-dimensional Chern-Simons theory. This may be thought of as encoding the quantum mechanics of a string propagating on the phase space of a system in classical mechanics.
In his solution of the problem of deformation quantization Maxim Kontsevich showed that correlators for the 2-string interaction (the correlator on the worldsheet that is a disk with three marked points on its boundary) describe a product operation which is a deformation of the Poisson bracket on the target space. This solves the formal deformation quantization problem of the phase space in quantum mechanics by identifying the quantum algebra with the open string algebra of a string theory on that target.
The principal variant of the nonlinear Poisson sigma model is sometimes called Cattaneo-Felder model who have shown the graphical expansion used in Kontsevich’s approach to the deformation quantization is explained via a Feynman diagram expansion in this model.
If one considers branes in the target space of the Poisson sigma-model, then then algebra of open strings that used to be just the deformation of the Poisson algebra becomes an A-infinity algebroid. (See the references below).

In (Cattaneo-Felder) it was shown that the 3-point function in the path integral quantization of the Poisson -model of a Poisson Lie algebroid associated with a Poisson manifold computes the star product in the deformation quantization of the Poisson manifold as given by (Kontsevich).
A higher geometric quantization that also yields the strict deformation quantization is discussed at extended geometric quantization of 2d Chern-Simons theory.
One may think of this relation between the 2d Poisson sigma-model and quantum mechanics = 1d quantum field theory as an example of the Chern-Simons type holographic principle. For more along these lines see below at holographic dual.
The branes of the Poisson sigma model are related to coisotropic submanifolds of the underlying Poisson manifold. Notice that these are the Lagrangian dg-submanifolds of the Poisson Lie algebroid. (Cattaneo-Felder 03).
By the Chern-Simons form of the holographic principle one expects the Poisson sigma-model to be related to a 1-dimensional quantum field theory. This is quantum mechanics. The above relation to the deformation quantization of Poisson manifolds goes in this direction. More explicit realizations have been attempted, for instance (Vassilevich).
