In this study, we investigate the phase diagram and thermodynamics of SU(N) pure Yang-Mills theory on a manifold T2 x R2 using an effective model that includes two Polyakov loops along two compactified directions. It is found that a rich phase structure can appear due to the spontaneous breaking of two center symmetries for N = 2 and 3. Thermodynamic quantities are obtained in the model and compared with recent lattice results, showing that the two Polyakov loops play significant roles in the thermodynamics on T2 x R2.
