Loss of Spin Entanglement For Accelerated Electrons in Electric and Magnetic Fields

TL;DR

This paper investigates how uniform acceleration in magnetic fields affects entanglement between two electrons, revealing that higher acceleration accelerates entanglement decay, with a specific relationship involving Rindler temperature.

Contribution

It introduces a quantum open system approach to analyze entanglement dynamics of accelerated electrons in magnetic fields, highlighting the impact of acceleration and temperature.

Findings

Entanglement diminishes faster at higher accelerations.

Proper time for entanglement loss scales inversely with the cube of acceleration.

High Rindler temperature accelerates entanglement extinction.

Abstract

Using an open quantum system we calculate the time dependence of the concurrence between two maximally entangled electron spins with one accelerated uniformly in the presence of a constant magnetic field and the other at rest and isolated from fields. We find at high Rindler temperature the proper time for the entanglement to be extinguished is proportional to the inverse of the acceleration cubed.
