Theoretical Problems in Condensed Matter and Statistical Physics

9714725纳尔逊这一更新授予这一高级杰出PI支持凝聚态物理和统计力学的各种主题的工作，重点是几何和无序之间的相互作用。 有一些项目是关于第二类超导体中与人工钉扎中心相互作用的涡旋、群体生物学中的局部化效应以及聚合物和囊泡中的热波动和动力学。 有计划考虑通过运行与外部磁场平行的外部电流来产生“加工硬化”状态的纠缠涡线。 在非均匀介质中具有对流的种群生物学的简单模型中，基本的数学结构对应于非厄米局部化问题，并且适合于细菌的实验室研究。 有计划在空间不均匀的环境中研究“Fisher波”。 这位资深杰出的PI因开拓性，创新性的研究而被广泛认可;精彩清晰，刺激和娱乐性的演讲以及对学生和博士后的精心培养。 他从事凝聚态物质和生物物理学的统计力学研究，范围从超导体到聚合物和囊泡。 他的工作在这个更新补助金还包含在人口生物学的本地化影响的项目。 ***

9714725 Nelson This renewal grant to this senior distinguished PI supports work on a variety of topics in condensed matter physics and statistical mechanics, with emphasis on interplay between geometry and disorder. There are projects on vortices interacting with artificial pinning centers in a type II superconductor, localization effects in population biology and thermal fluctuations and dynamics in polymers and vesicles. There are plans to consider ways of producing a "work-hardened" state of tangled vortex lines by running an external current parallel to the external magnetic field. In simple models of population biology with convection in heterogeneous media, the underlying mathematical structure corresponds to a non-Hermitian localization problem and is amenable to laboratory investigation with bacteria. There are plans to study "Fisher waves" in a spatially inhomogeneous environment. %%% This senior distinguished PI is widely recognized for pioneering, innovative research; wonderfully lucid, stimulating and entertaining presentations and a careful nurturing of students and postdocs. He works on the statistical mechanics of condensed matter and biophysics, ranging from superconductors to polymers and vesicles. His work in this renewal grant also contains projects on localization effects in population biology. ***
