The rapid structural and vibrational entropy decrease with decreasing temperature in undercooled liquids is explained in terms of the disappearance of local structural instabilities, which freeze in at the glass temperature as boson peak modes and low temperature tunneling states. At the Kauzmann temperature, their density extrapolates to zero, as evidenced by neutron and heat capacity data in liquid selenium.
