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

TL;DR

This paper investigates the properties of ripplonic polarons in a quasi-one-dimensional electron system on liquid helium, focusing on their energetics, localization, and potential experimental observation at very low temperatures.

Contribution

It introduces a hydrodynamic model to calculate polaron energies and localization lengths, and estimates the temperature for polaron formation, providing new insights into their behavior in this system.

Findings

Polaron bound energy is determined.

Polaron formation occurs below 0.1 K.

Potential experimental methods for observing polarons are discussed.

Abstract

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.
