Hartle-Hawking state is a maximum of entanglement entropy
It is shown that the Hartle-Hawking state of a scalar field is a maximum of
entanglement entropy in the space of pure quantum states satisfying the
condition that backreaction is finite. In other words, the Hartle-Hawking state
is a curved-space analogue of the EPR state, which is also a maximum of
entanglement entropy.Comment: Latex, 4 pages, Some comments are added on the "small backreaction

Kinetic Equations for Longwavelength Excitations of the Quark-Gluon Plasma
We show that longwavelength excitations of the quark-gluon plasma are
described by simple kinetic equations which represent the exact equations of
motion at leading order in . Properties of the so-called ``hard thermal
loops'', i.e. the dominant contributions to amplitudes with soft external
lines, find in this approach a natural explanation. In particular, their
generating functional appears here as the effective action describing long
wavelength excitations of the plasma.Comment: January 8, 1993; 8 pages; SPhT/93-
