中文摘要
量子涨落可以在电子之间强相互作用的金属中导致奇异的有序现象。这种波动在绝对零度的量子相变附近变得特别强烈。在这些量子临界点附近,发现了各种新的物质相,如非常规的超导性和奇异的磁态。近藤晶格系统表现出与传导电子相互作用的局部磁矩,这种行为甚至更丰富。该研究项目的目的是利用多体场理论的技术,如微扰图计算和重整化群,从理论上分析这些材料中的奇异有序现象。其目的是在基本层面上理解潜在的波动驱动的排序机制。从长远来看,这些知识可能会转化为技术应用。
英文摘要
Quantum fluctuations can lead to exotic ordering phenomena in metals with strong interactions between electrons. Such fluctuations become particularly strong in the vicinity of quantum phase transitions at absolute zero temperature. In the vicinity of such quantum critical points various novel phases of matter are found, such as unconventional superconductivity and exotic magnetic states. The behaviour is even richer in Kondo lattice systems which exhibit local magnetic moments that are interacting with the conduction electrons. The aim of the research project is to theoretically analyse exotic ordering phenomena in such materials, using techniques from many-body field theory, such as perturbative diagrammatic calculations and the renormalisation group. The aim is to understand the underlying fluctuation-driven ordering mechanisms at a fundamental level. This knowledge might feed into technological applications in the long term.
