The goal of this Faculty Early Career Development (CAREER) project at Duke University is to experimentally investigate dynamic and quenched disorder in non-equilibrium reaction-diffusion processes, and to further incorporate research experience into the graduate and undergraduate physics curriculum. Despite the ubiquity and importance of processes involving interaction and transport: e.g. the weather, plasmas, industrial chemical reactions and surface reactions, a quantitative understanding of non-equilibrium processes is fundamentally lacking. The proposed experiments address open questions in non-equilibrium physics, including studies of the validity of the Kardar-Parisi-Zhang model of rough growing interfaces, and tests of whether a critical amount of disorder smooths out a non-equilibrium transition that is otherwise sharp. These studies will contribute to the development of a predictive theory for non-equilibrium physics. Training of students will focus on their preparation for scientific and non-scientific multidisciplinary careers, while still maintaining the useful perspective and skills provided by a physics program.The goal of this Faculty Early Career Development (CAREER) project at Duke University is to experimentally investigate dynamic and static disorder in non-equilibrium processes involving interaction and transport, and to further incorporate research experience into the graduate and undergraduate physics curriculum. Despite the ubiquity and importance of interaction-transport processes: e.g. the weather, plasmas, industrial chemical reactions and surface reactions, a theoretical understanding, i.e. predictive power, of these processes is fundamentally lacking. The proposed experiments address open questions in non-equilibrium physics, including studies of the validity of the Kardar-Parisi-Zhang model of rough growing interfaces, and tests of whether a precise amount of disorder smooths out an otherwise sharp transition between two different system behaviors. The results of these experiments will contribute to the development of a predictive theory of non-equilibrium systems which will ultimately apply to the research of liquid and solid rocket propellant and other combustion processes; electronic, magnetic, and optical materials fabrication; and bio-geophysical processes; and is likely to apply to a broad range of related phenomena. Training of students will focus on their preparation for scientific and non-scientific multidisciplinary careers, while still maintaining the useful perspective and skills provided by a physics program.

杜克大学的教师早期职业发展（CAREER）项目的目标是通过实验研究非平衡反应扩散过程中的动态和淬灭无序，并进一步将研究经验纳入研究生和本科生物理课程。 尽管涉及相互作用和传输的过程的普遍性和重要性：例如天气，等离子体，工业化学反应和表面反应，但从根本上缺乏对非平衡过程的定量理解。 拟议中的实验解决了非平衡物理学中的未决问题，包括研究粗糙生长界面的Kardar-Parisi-Zhang模型的有效性，以及测试临界量的无序是否平滑了非平衡转变。 这些研究将有助于发展非平衡态物理的预测理论。对学生的培训将侧重于他们为科学和非科学多学科职业生涯做准备，同时仍然保持物理课程提供的有用观点和技能。杜克大学的这个教师早期职业发展（CAREER）项目的目标是实验研究涉及相互作用和运输的非平衡过程中的动态和静态无序，并进一步将研究经验纳入研究生和本科生的物理课程。 尽管相互作用传输过程的普遍性和重要性：例如天气，等离子体，工业化学反应和表面反应，这些过程的理论理解，即预测能力，是根本缺乏。 拟议的实验解决了非平衡物理学中的未决问题，包括研究粗糙生长界面的Kardar-Parisi-Zhang模型的有效性，以及测试精确数量的无序是否平滑了两种不同系统行为之间的急剧过渡。 这些实验的结果将有助于非平衡系统的预测理论的发展，最终将适用于液体和固体火箭推进剂和其他燃烧过程的研究;电子，磁性和光学材料制造;和生物地球物理过程;并可能适用于广泛的相关现象。对学生的培训将侧重于他们为科学和非科学多学科职业做准备，同时仍然保持物理课程提供的有用观点和技能。
