Abstract

Whether or not a generic nonequilibrium process, nonlinear and without detailed balance, possesses an effective Hamiltonian has been an outstanding question for a long time. It was attempted by many researchers without success, such as those by Prigogine and his school. In fact, many physicists and mathematicians tend to harbor a negative answer. Motivated by our biological study recently we have found a solution to this important question. I will talk about what we have done, important experimental tests, and, a conjecture motivated by dissipative quantum dynamics.

敖平现为上海大学定量生命科学国际研究中心特聘教授和物理系教授, 教育部长江学者奖励计划特聘教授, 国家"973计划"首席科学家。1983年毕业于北京大学物理系后由李政道CUSPEA项目赴美留学。1990年获美国伊利诺大学香槟分校(UIUC)物理学博士, 导师为诺贝尔奖获得者Prof. A.J. Leggett; 1990-1994年, 在美国华盛顿大学物理系从事博士后研究, 导师为诺贝尔奖获得者Prof. D. J. Thouless。1994任瑞典Umea 大学助理教授, 并很快晋升为副教授。2000-2003年, 作为高级科学家以及访问副教授加盟西雅图的美国系统生物学研究所, 与研究所创始人之一Leroy Hood教授(美国科学院、工程院和医学院院士)从事系统生物学研究; 2003-2009年, 任华盛顿大学机械工程系副教授。敖平教授研究跨越生物、工程和物理。他在宏观量子效应方面的工作至今为人引用。与人合作他率先用拓扑方法建立了超导涡旋动力学基本方程, 预测玻色-爱因斯坦凝聚一种二相量子混和。在生物领域他独立澄清了进化生物学中的两个重要基本理论问题。对复杂疾病机理他首先提出癌症产生和发展的新理论: 癌症的分子网络内因; 并发展相应数学和计算工具: 随机过程中的势函数。此新学说正在国际上逐渐获得重视并有取代癌基因和基因组学说趋势。
