摘要：

A new expression of the dissipative dc conductance is presented in terms of the scattering phase shift by a time dependent Aharonov-Bohm flux line. It is then related to the Thouless conductance defined as the curvature of the energy levels under a change of the boundary conditions. The relation between these two conductances is found to be universal for all systems obeying Wigner-Dyson statistics. This provides a new characterization of quantum chaotic systems.
