Exotic Phenomena in Highly Frustrated Magnetic Systems

在物理学中，当几个微观相互作用相互竞争，并且不能同时满足最小化系统的经典能量时，就会出现挫折感。具有激烈竞争或受挫交互的物理系统无处不在。例子包括中子星、蛋白质、生物膜和磁性材料中的核物质。多年来，人们通过对“常规”(非受挫)磁系统的实验和理论研究，发现了支配自然界非受挫系统中平衡集体现象的大多数基本原理。同样，人们预计，对高度受挫的磁铁的研究将引导我们揭示在具有强烈竞争相互作用的系统中起作用的原理。这项研究计划的目标是贡献我们在受挫磁性领域的知识，并通过解释在真实受挫磁性材料中发挥作用的复杂现象和通过预测激励新的实验研究的新效应来做到这一点，从而有助于推动该领域的发展。

In physics, frustration arises when several microscopic interactions compete and cannot be simultaneously satisfied to minimize the classical energy of the system. Physical systems with strongly competing, or frustrated, interactions are ubiquitous. Examples include nuclear matter in neutron stars, proteins, biological membranes and magnetic materials. Most of the fundamental principles that govern equilibrium collective phenomena in non-frustrated systems of Nature have been discovered over the years through experimental and theoretical studies of "conventional" (non-frustrated) magnetic systems. Likewise, one expects that studies of highly frustrated magnets will lead us to uncover the principles at work in systems with strongly competing interactions. It is the goal of this research program to contribute to our knowledge in the field of frustrated magnetism and to do so by explaining complex phenomena at play in real frustrated magnetic materials and by predicting novel effects that motivate new experimental studies and hence contribute to drive the field forward.
