Ripplonic Polaron in the Quasi-One-Dimensional Electron System over Liquid Helium

We study the energetics and transport properties of polarons in the quasi-one dimensional electron system over the liquid helium surface. The localization lengths and the energy of the ground and excited states are calculated within the hydrodynamic model of the polaron. The polaron bound energy is found and the temperature for the polaron formation is estimated below 0.1 K. We examine the possibility of observation of the polarons by measuring both the spectroscopic transitions and the mobility.
