In 2013, Goncharov and Kenyon constructed integrable systems from a class of quivers on a torus, parametrized by integral convex polygons. Associating a Y-pattern to the quiver, the phase space coordinates of the dynamical systems are y-variables together with two extra variables. A Y-seed mutation at a vertex having two incoming and two outgoing arrows gives a change of coordinates. We study this dimer integrable system on Cluster variables, extend it to some quivers outside the class, and construct conserved quantities of Q-systems.
