We evaluate the static qqqq ¯ q potential in the quenched theory at β = 5.8 and β = 6.0 on a lattice of size 16 3 × 32. The mass and density-density correlator for the Θ + is investigated in the quenched theory at β = 6.0 on lattices of size 16 3 × 32, 24 3 × 32 and 32 3 × 64.

In this paper we consider the Interband Light Absorption Coefficient for various models. We show that at the lower and upper edges of the spectrum the Lifshitz tails behaviour of the density of states implies similar behaviour for the ILAC at appropriate energies. The Lifshitz tails property is also exhibited at some points corresponding to the internal band edges of the density of states.
