Optomechanical Entanglement under Pulse Drive

TL;DR

This paper investigates how optomechanical entanglement evolves when driven by laser pulses with various shapes and detunings, especially in high-temperature environments, using a novel approach due to the lack of steady state.

Contribution

It introduces a new method to analyze optomechanical entanglement under pulsed drive conditions, differing from traditional steady-state approaches.

Findings

Entanglement dynamics depend on pulse shape and detuning.

High temperature affects entanglement evolution.

A novel analytical approach for pulsed optomechanical systems.

Abstract

We report a study of optomechanical entanglement under the drive of one or a series of laser pulses with arbitrary detuning and different pulse shapes. Because of the non-existence of system steady state under pulsed driving field, we adopt a different approach from the standard treatment to optomechanical entanglement. The situation of the entanglement evolution in high temperature is also discussed.
