Abstract: In this talk, I consider the quantum state of an electromagnetic field in contact with dielectric matter. The presence of field entropy at zero temperature signals the inevitable entanglement between the field and the material. I estimate the effect of dissipation and dispersion on the effective state of the field and the cutoff dependence of the field entropy. Finally, I show formulas for the part of the entanglement entropy associated with the distance between two disperssive objects, in a philosophy similar to the one used in Casimir physics.
