CAREER: Fluctuations, Dissipation, and Phase Transitions in Vortex States of High-Tc Superconductors

Radzihovsky （Radzihovsky）这是一项针对年轻教师的职业补助金，旨在将研究与教育结合起来。该理论项目将解决高温超导体现象学中的两个主要问题：(i)涡旋液体的平衡和非平衡性质，目的是推导目前假设的流体力学描述，并阐明涡旋状态、不稳定性和在平行于外加磁场的电流存在下的耗散；（ii）涡旋液体向固相的冻结转变，这将包括发展一种新的平均场描述，该描述明确显示涡旋有序进入晶格的能量趋势，并可推广到包括波动的影响。这些研究工作将通过开发新课程和让各级学生参与研究而得到教育方面的补充。这是一笔给年轻教师的职业补助金，用于研究和教育相结合的项目。理论研究将集中在高温超导体中物质的独特状态的性质上。教育部分将侧重于课程开发和各级学生融入研究计划。

w:\awards\awards96\career\0formca.doc 9625111 Radzihovsky This is a CAREER grant to a young faculty member which combines research and education. The theoretical project will address two major problems in the phenomenology of high temperature superconductors: (i) the equilibrium and nonequilibrium properties of the vortex liquid, with the goals of the derivation of the currently assumed hydrodynamic description, and elucidation of the vortex states, instabilities and dissipation in the presence of currents parallel to the applied magnetic field; (ii) the freezing transition of the vortex liquid into a solid phase, which will consist of the development of a new mean-field description that explicitly shows the energetic tendency of the vortices to order into a lattice and which is generalizable to including the effects of fluctuations. These research efforts will be complemented by the educational component through new course development, and incorporation of students at all levels into research. %%% This is a CAREER grant t a young faculty member for a program which combines research and education. The theoretical research will focus on the properties of unique states of matter which occur in the high temperature superconductors. The educational component will focus on course development and integration of students at all levels into the research program.
