Electron Wave Function Distribution Change in Mesoscopic Systems

TL;DR

This paper reports a new phenomenon where electron wave packet sizes change with kinetic energy transfer, impacting electron transport in various nanotechnologies and quantum systems.

Contribution

It introduces a novel effect of wave packet size variation linked to kinetic energy transfer in electrons across physical systems.

Findings

Electron wave packet size decreases when electrons transfer kinetic energy.

Wave packet size enlarges when electrons gain kinetic energy.

Effect is observed in a wide range of physical systems.

Abstract

We find a new phenomenon, a particle like an electron, which transfers kinetic energy to other subject undergoes a decrease in its wave packet size in space and an electron that gains kinetic energy experiences an enlargement of its wavepacket size. This effect occurs in some amount of degree almost in any physical system. The effect has significance on electron transport in semiconductors, quantum wires, future devices in nanotechnology and quantum optics.
