Thermodynamics of scalar-tensor theory with non-minimally derivative coupling
With the usual definitions for the entropy and the temperature associated
with the apparent horizon, we show that the unified first law on the apparent
horizon is equivalent to the Friedmann equation for the scalar--tensor theory
with non-minimally derivative coupling. The second law of thermodynamics on the
apparent horizon is also satisfied. The results support a deep and fundamental
connection between gravitation, thermodynamics, and quantum theory.Comment: 12 pages, no figure, minor correction
