Query: Revisiting Thouless conductance formula   It was shown using perturbation theory[1] that Thouless energy Ec for a
quantum system scales linearly with the conductance of the system. We derive in
an alternate way in 1-D that Ec scales with the conductance in a very different
way. We physically show the difference between our approach and that of ref. 1
to expect our results to hold in higher dimensions also. We verify our results
with exact numerical calculations.
