Abstract

“Stripes”— meaning unidirectional charge-density-waves, sometimes (but not always) accompanied by spin-density-waves with twice the period - are now known to arise in broad swathes of the cuprate phase diagram, and appear as a strong ordering tendency in numerical studies of Hubbard-like models of highly correlated electron systems. Jan Zaanen’s work played a seminal role in predicting their existence, and exploring their possible significance. They are not related to any weak-coupling physics associated with some form of Fermi-surface nesting. And whether one likes them or not, they are surprisingly difficult to avoid; in the Hubbard model, for example, they often appear as an alternative order that can out-compete the otherwise favored

“条纹”在铜合金、哈伯德模型和其他高度相关的电子系统的物理学中的意义

“条纹”——意思是单向的电荷密度波，有时（但并不总是）伴随着两倍周期的自旋密度波——现在已知出现在铜相图的宽条纹中，并且在高度相关电子系统的哈伯德类模型的数值研究中表现出强烈的有序趋势。Jan Zaanen的工作在预测它们的存在和探索它们可能的意义方面发挥了开创性的作用。它们与任何与某种形式的费米表面嵌套相关的弱耦合物理无关。不管你喜不喜欢，它们都是难以避免的；例如，在哈伯德模型中，它们经常作为一种替代顺序出现，可以与其他受欢迎的d波超导性竞争。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
