Comment on "Observations of 2D Polarons and Magneto-Polarons on Superfluid Helium Films"
Abstract
Description
A recent experimental Physical Review Letter which claims to prove the existence of the single-electron ripplonic polaron associated with electrons on a helium film is examined. A correct evaluation of the holding field and a restriction of the polaron radius to the Wigner-Seitz radius lead to a gross discrepancy between experiment and theory. The polaron is not bound under the experimental conditions.
