百年物理难题“时间箭头”研究获重要理论突破

Core Insights - The research team led by Professor Cai Qingyu from Hainan University has made significant progress in addressing the century-old scientific challenge of "time's arrow" and the principle of entropy increase, providing a theoretical foundation for the interpretation of these concepts from a quantum mechanics perspective [1][2] Group 1: Research Findings - The team revealed the irreversibility generated by quantum system correlations, which offers a breakthrough theoretical explanation for the long-standing contradiction between the reversible dynamics at the microscopic level and the observed macroscopic "arrow of time" [1] - A key "no-go theorem" was established, demonstrating that there is no universal physical operation in a closed quantum system that can completely eliminate correlations between arbitrary unknown quantum states [1] - The research created a unified theoretical framework that attributes irreversible phenomena, such as heat flow from high to low temperature and the evolution of isolated systems towards equilibrium, to the continuous generation of correlations that are difficult to reverse [1] Group 2: Expert Evaluation - Academician Sun Changpu from the Chinese Academy of Sciences highly praised the research, stating that it provides a solid theoretical basis for the interpretation of entropy increase and time's arrow from a quantum mechanics perspective, revealing the core role of quantum and classical correlations in physics [2]
