GRK 1558: Nonequilibrium Collective Dynamics in Condensed Matter and Biological Systems

相互作用电子通过半导体量子点系综的非平衡输运揭示了这些电子之间的量子相关性。纳米棒悬浮在水溶液中，在剪切流的驱动下表现出复杂的运动模式，包括混沌特征。神经元通过沿轴突行进的动作电位脉冲相互作用，产生非线性激励波。这是我们将在研究培训组学习的三个系统示例。为了涵盖该主题的广度，我们针对不同的材料系统建立了三个重点项目领域的研究计划。在硬凝聚态中，我们专注于半导体纳米结构中的非线性输运和量子光学。在软物质系统中，我们研究了分散的胶体粒子的集体动力学及其在水溶剂中的流体动力学相互作用。最后，研究了活性生物介质（如生物膜、神经系统和心脏）中的自组织和非线性波。研究培训小组是一个跨学科的倡议，其目的是在相互作用的实体的非平衡集体动力学的描述中揭示共同的特征和方法。因此，物理学和生物学各自的研究领域有望出现新的观点。该研究计划是理论项目的结合，与实验和两个实验组的参与密切相关。虽然研究计划侧重于基础研究，但它也受到潜在应用的激励，例如在新型光子和微流体装置以及医学方面。研究培训小组的跨学科方法是广泛而深入的教育的理想选择，这将提高学生在工业就业市场和博士后职位的机会。因此，我们建立了一个学习计划和资格概念，以支持学生的跨学科培训。我们特别邀请来自应用研究和工业界的研讨会演讲者报告与研究培训小组研究计划有关的应用。学生学业的成功将由两到三名博士论文导师的协调行动积极监督。

The nonequilibrium transport of interacting electrons through an ensemble of semiconductor quantum dots reveals quantum correlations between these electrons. Nanorods suspended in an aqueous solvent and driven by an imposed shear flow display complex motional patterns including chaotic features. Neurons that interact via action-potential pulses travelling along axons give rise to nonlinear excitation waves. These are three examples of systems we will study within the Research Training Group. To cover the topic in its breadth, we set up a research programme with three focussed project areas for different material systems. Within hard condensed matter, we concentrate on nonlinear transport and quantum optics in semiconductor nanostructures. In soft matter systems, we investigate the collective dynamics of dispersed colloidal particles and their hydrodynamic interactions in aqueous solvents. Finally, selforganisation and nonlinear waves in active biological media, such as biofilms, neural systems and the heart, are studied. The Research Training Group is an interdisciplinary initiative in the sense that it aims to unravel common features and methods in the description of the nonequilibrium collective dynamics of interacting entities. Thereby, novel views on the respective research fields from physics and biology are expected to emerge. The research programme is a combination of theoretical projects, with strong links to experiments and the participation of two experimental groups. Although the research programme concentrates on basic research, it is also motivated by potential applications, e.g., in novel photonic and microfluidic devices and in medicine. The interdisciplinary approach of the Research Training Group is ideal for a broad and in-depth education that will enhance the students chances in the job market in industry and for postdoctoral positions. We therefore set up a study programme and qualification concept that supports the students interdisciplinary training. In particular, we invite seminar speakers from applied research and industry who report on applications that are connected to the research programme of the Research Training Group. Success in the students studies will be actively monitored by the concerted action of two to three supervisors of their PhD theses.
