We study the entanglement entropy arising from coherent states and one-particle states. We show that it is possible to define a finite entanglement entropy by subtracting the vacuum entropy from that of the considered states, when the unobserved region is the same.

Abtttract-Two expressions for the entropy of isolated polymer chains in general, and Gaussian chains in particular, are examined, and the correct expression indicated. In particular, it is shown that the Wall equation for the entropy change upon perturbation of a Gaussian chain is correct.
