  This note aims to subsume several apparently unrelated models under a common
framework. Several examples of well-known quantum field theories are listed
which are connected via stochastic quantization. We highlight the fact that the
quantization method used to obtain the quantum crystal is a discrete analog of
stochastic quantization. This model is of interest for string theory, since the
(classical) melting crystal corner is related to the topological A-model. We
outline several ideas for interpreting the quantum crystal on the string theory
side of the correspondence, exploring interpretations in the Wheeler-De Witt
framework and in terms of a non-Lorentz invariant limit of topological
M-theory.
