Abstract

A possibility of a quantum single electron soliton (QSES) formation in structures with different dimensionality (0, 1, 2, and 3D) and spectrum (parabolic and linear) placed near metal surface is discussed. These solitons originate as solutions of the nonlinear Schrodinger equation allowing for interaction with image charges in metal. The binding energy of those quasi-particles could exceed the thermal energy at room temperature.
