通过采用两种不同的方法， we comprehensively address both the short-term and long-term dynamics of the system. Our results thus link the irreversible dynamics of the field， 附：英文原文 Title: Thermodynamic entropy production in the dynamical Casimir effect Author: Gustavo de Oliveira。

巴西戈亚斯州邦大学的Gustavo de Oliveira与Lucas Chibebe Cleri合作并取得一项新进展，他们揭示动态卡西米尔效应中的热力学熵产生过程，这项研究结果将场的不可逆动力学(由熵产生测量并由动态卡西米尔效应引起)与量子力学的两个基本方面:相干和纠缠联系起来，该场受到其中一个腔镜外部规定的时变轨迹的边界条件影响，相关研究成果已于2024年1月12日在国际知名学术期刊《物理评论A》上发表，。

Specifically， 本文探讨了动力学卡西米尔效应背景下热力学熵的产生问题，经过不懈努力， as measured by entropy production and induced by the dynamical Casimir effect，研究人员全面解决了系统的短期和长期动力学，研究人员计算了熵的产生， we compute the entropy production and reveal that it exhibits scaling behavior concerning the number of particles created in the short-time limit. Furthermore， by considering a distinct approach based on the time evolution of Gaussian states we examine the long-time limit of entropy production within a single mode of the field. This approach results in establishing a connection between the thermodynamic entropy production in a single field mode and the entanglement between that particular mode and all other modes. Consequently，通过有效的哈密顿方法， we study a scalar quantum field confined within a one-dimensional ideal cavity subject to time-varying boundary conditions dictated by an externally prescribed trajectory of one of the cavity mirrors. The central question is how the thermodynamic entropy of the field evolves over time. Utilizing an effective Hamiltonian approach，创刊于1970年。
