Escape of trapped electrons from a helium surface: a dynamical theory

TL;DR

This paper develops a dynamical theory to describe how electrons escape from a helium surface, accounting for electron correlations and magnetic fields, providing analytical escape rate formulas including tunneling with magnetic influence.

Contribution

It introduces a new dynamical framework that includes electron-electron interactions and magnetic effects, with explicit formulas for escape rates.

Findings

Analytical expressions for escape rates derived

Tunneling rate with parallel magnetic field explicitly presented

Theory incorporates electron correlations and magnetic effects

Abstract

We present a dynamical theory which incorporates the electron-electron correlations and the effects of external magnetic fields for an electron escaping from a helium surface. Analytical expressions for the escape rate can be obtained in various limits. In particular, the tunneling rate with a parallel magnetic field is presented explicitly.
