    • insulate To make an island of (a place) by surrounding it with water.
    • insulate To place in an isolated situation or condition; set apart from immediate contact or association with others; detach; segregate.
    • insulate In electricity and thermotics, to separate, as an electrified or heated body, from other bodies by the interposition of a non-conductor; more specifically, in the case of electricity, to separate from the earth (since an electrified body tends to part with its electricity to the earth). This is accomplished by supporting the body by means of silk, glass, resin, or some other non-conductor, or surrounding it with such materials. See insulator. Also isolate.
    • insulate In chem., to free from combination with other substances.
    • insulate In entomology, detached from other parts or marks of the same kind.

Also in the Anderson insulator, reconstruction of the charge by transferring electrons above the tunneling barrier could occur.
Anderson Localization and Polarization
In thermodynamic limit, χ is diverging if the system is metallic, but converging to a finite value if it is an insulator.
Anderson Localization and Polarization
W = 3, χ is convergent to a finite value which is consistent with the insulating ground state.
Anderson Localization and Polarization
This approach is called the scaling theory of localization, and deals with the conditions under which a system is metallic, insulating, or undergoes a transition between the two states.
