近日，巴西戈亚斯联邦大学的Lucas C. Céleri及其研究团队取得一项新进展。经过不懈努力，他们通过量子动力学临界性加速热力学熵的产生。相关研究成果已于2024年11月25日在国际知名学术期刊《物理评论A》上发表。

本研究通过从几何角度审视熵产生，将动力学临界性与热力学联系起来，在这一领域取得了进展。研究发现，结合其他最新研究成果，表明动力学临界性可以引导系统产生高度复杂的动力学行为，这可能为热化过程提供了一条可能的途径。

据悉，量子相变的热力学长期以来一直是研究领域的热点，为人们提供了大量见解，并加深了对这一重要现象的理解。这一理论框架之所以得到了充分发展，特别是因为量子相变发生在平衡状态下。然而，其动力学对应物，即动力学量子相变，则发生在非平衡状态下，此时传统的热力学工具不再适用。

Abstract: The thermodynamics of quantum phase transitions has long been a rich area of research, providing numerous insights and enhancing our understanding of this important phenomenon. This theoretical framework has been well developed specially because quantum phase transitions occur at equilibrium. However, its dynamical counterpart, known as dynamical quantum phase transitions, takes place out of equilibrium, where conventional thermodynamic tools are inapplicable. In this work we make progress in this area by connecting dynamical criticality to thermodynamics through a geometric perspective on entropy production. Our findings, along with other recent developments, suggest that dynamical criticality can lead the system to highly complex dynamics, indicating a possible pathway to thermalization.
