Query: Polyakov Loop Models, Z(N) Symmetry, and Sine-Law Scaling   We construct an effective action for Polyakov loops using the eigenvalues of
the Polyakov loops as the fundamental variables. We assume $% Z(N)$ symmetry in
the confined phase, a finite difference in energy densities between the
confined and deconfined phases as $T\to 0$, and a smooth connection to
perturbation theory for large $T$. The low-temperature phase consists of $N-1$
independent fields fluctuating around an explicitly Z(N) symmetric background.
In the low-temperature phase, the effective action yields non-zero string
tensions for all representations with non-trivial $N$-ality. Mixing occurs
naturally between representations of the same $N$-ality. Sine-law scaling
emerges as a special case, associated with nearest-neighbor interactions
between Polyakov loop eigenvalues.
