This three-year award supports U.S.-Ireland cooperative research in theoretical physics between Robert F. O'Connell of Louisiana State University and J.T. Lewis of the Dublin Institute of Advanced Studies. The investigators will study stochastic processes in quantum systems with special emphasis on systems in quantum optics and lasers, atomic and condensed matter physics which involve the presence of a heat bath as an integral element. They will address the spin-boson problem where a two-level system interacts with a radiation field, and problems on blackbody radiation heat-bath and dissipative quantum tunneling. The investigators will apply their results and methodology to study the effects of quantum dissipation in systems that exhibit the phenomenon of chaos. The U.S. group are experts in the theoretical aspects of quantum stochastic processes. The Irish investigators bring complementary expertise in the theoretical and experimental aspects of chaos in semiconductor lasers. Research in quantum stochastic processes have wide implications for a variety of systems in physics. This research will advance our understanding of quantum electrodynamics, condensed-matter physics, laser physics and atomic physics.

这个为期三年的奖项支持路易斯安那州立大学的罗伯特·f·奥康奈尔和都柏林高等研究所的J.T.刘易斯在理论物理学方面的美国-爱尔兰合作研究。研究人员将研究量子系统中的随机过程，特别强调量子光学和激光系统，原子和凝聚态物理，其中涉及热浴作为一个整体元素的存在。他们将解决两能级系统与辐射场相互作用的自旋玻色子问题，以及黑体辐射热浴和耗散量子隧道的问题。研究人员将应用他们的结果和方法来研究量子耗散在表现混沌现象的系统中的影响。美国小组是量子随机过程理论方面的专家。爱尔兰研究人员在半导体激光器混沌的理论和实验方面带来了互补的专业知识。量子随机过程的研究对物理学中的各种系统具有广泛的意义。这项研究将促进我们对量子电动力学、凝聚态物理、激光物理和原子物理的理解。
