摘要
In this paper, we consider one-dimensional adiabatic quasi-periodic Schrodinger operators in the regime of strong resonant tunneling. We show the emergence of a level repulsion phenomenon which is seen to be very naturally related to the local spectral type of the operator: the more singular the spectrum, the weaker the repulsion.
