9975480HirschfeldThis award supports research on transport properties of unconventional superconductors in the mixed state. The PI wants to continue work on superconductors that have order parameters of d-wave symmetry and to address fundamental open questions such as the thermal conductivity in the vortex state and the influence of induced superconducting phases. Extensions to different experimental configurations and to higher temperatures will also be performed. The PI plans to explore the interplay between nonlocal and nonlinear effects in the electromagnetic response. Finally, the PI intends to investigate the microscopic nature of impurity scattering in unconventional superconductors and the interference of elastic and inelastic scattering. This award supports research into the properties of high temperature and heavy fermion superconductors. The PI seeks to understand transport properties of the novel superconducting states of these materials in applied magnetic fields that are sufficiently large so that vortices appear in the superconducting state. Unlike most known superconductors, the Cooper pairs that comprise the superconducting states of these materials have d-wave symmetry which will can lead to new physical phenomena and qualitatively different transport properties. In addition, this award provides educational opportunity for the next generation of scientists.

9975480Hirschmann该奖项支持非常规超导体在混合状态下的输运特性研究。PI希望继续研究具有d波对称序参数的超导体，并解决基本的开放问题，如涡旋态的热导率和诱导超导相的影响。 扩展到不同的实验配置和更高的温度也将进行。 PI计划探索电磁响应中非局部和非线性效应之间的相互作用。 最后，PI打算研究非常规超导体中杂质散射的微观本质以及弹性和非弹性散射的干涉。该奖项支持对高温和重费米子超导体性质的研究。 PI试图了解这些材料在足够大的磁场中的新型超导状态的传输特性，以便在超导状态下出现涡流。 与大多数已知的超导体不同，构成这些材料的超导态的库珀对具有d波对称性，这将导致新的物理现象和性质上不同的输运性质。 此外，该奖项为下一代科学家提供了教育机会。
