Description
We study a complex fermion model with SYK like interaction, in the
presence of a chemical potential. In the large q-limit we can solve the
model and obtain the Lyapunov exponent using semi-analytic methods. We find
that the Lyapunov exponent is a sensitive function of the chemical
potential. By appropriately adjusting the couplings and the chemical
potential, the Lyapunov exponent can be tuned to any value below the bound.
