Entropy Bound Derived from the New Thermodynamics on Holographic Screen
  We introduce a new interpretation of chemical potential and show that
holographic entropy is entropy bound, which is supported by two ideal cases
discussed in detail. One is sparse but incompressible liquid like a star of
uniform density and the other is a screen at infinity in spherically symmetric
sapcetime. Our work is based on the new scenario of entropy force and
holographic thermodynamics, and the Brown-York quasi-local energy.
