摘要

引力猫态是量子态的叠加，表现出宏观上不同的引力场。这些状态代表了量子力学和广义相对论的独特融合，为量子系统在引力影响下的行为提供了见解。本研究探讨了热环境对引力猫态可提取功的影响，引力猫态是不同引力构型的量子叠加。研究旨在全面分析质量为 m 的状态之间的温度和引力相互作用如何影响功的提取。研究结果表明，温度的升高和态之间的相互作用都会减少从引力猫态中提取的功，这凸显了量子系统中热效应和引力效应之间的微妙平衡。

Extracting work from two gravitational cat states

Gravitational cat states in the context of gravity are superpositions of quantum states that exhibit macroscopically distinct gravitational fields. These states represent a unique blend of quantum mechanics and general relativity, providing insights into the behavior of quantum systems under gravitational influences. This study investigates the impact of thermal environments on the extractable work from gravitational cat states, which are quantum superpositions of distinct gravitational configurations. It aims to offer a comprehensive analysis of how temperature and gravitational interactions between states with masses m influence work extraction. The findings indicate that both an increase in temperature and the interactions between states reduce the amount of work that can be extracted from gravitational cat states, highlighting the delicate balance between thermal and gravitational effects in quantum systems.

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
