Unconventional Hall effect induced by Berry curvature

Berry phase and Berry curvature play a key role in the development of topology in physics and do contribute to the transport properties in solid state systems. In this paper, we report the finding of novel nonzero Hall effect in topological material ZrTe₅ flakes when the in-plane magnetic field is parallel and perpendicular to the current. Surprisingly, both symmetric and antisymmetric components with respect to magnetic field are detected in the in-plane Hall resistivity. Further theoretical analysis suggests that the magnetotransport properties originate from the anomalous velocity induced by Berry curvature in a tilted Weyl semimetal. Our work not only enriches the Hall family but also provides new insights into the Berry phase effect in topological materials.

伊丽莎白·毕肖普诗歌的拉康式解读

美国女诗人伊丽莎白·毕肖普早期不幸的遭遇使其在作品中流露出"渴望"与"缺失"。尽管如此,诗人从未停止在"缺失"中探究和思考,寻找自我认同。本文结合拉康的"无意识"理论、镜像阶段对毕肖普的诗歌进行解读,探究诗人在其诗歌中的自我构建过程以及诗歌背后隐藏的"潜文本"。     

一个“不可捉摸”的“网”——伊丽莎白·乔利作品“另类”主题初探

生活是一种态度,生存是一种状态。世界是一个有秩序的物体,社会是一个理性的环境。形形色色的人生活在大千世界中,寻找着方向,追求着目标。人需要关怀,需要理解,需要引导,需要和谐;但必须共同维护秩序,理性地生活,践踏他人换取的虚无的快乐是真实的痛苦。当代著名的澳大利亚作家伊丽莎白·乔利通过刻画“小人物”的故事,关注“另类”主题,旨在唤醒人们的良知,使其找回自我,找到理想的空间。

Readjustment problems of Brazilian returnees from graduate studies in the United States

This is a pilot study on the readjustment problems of Brazilians returned from graduate study in the United States. Subjects were 31 former LASPAU scholars who were interviewed by the senior author after they were back in Brazil. The family and professional problems they experienced as they tried to readjust to life in their country were investigated, as well as the intensity of these problems and the adequacy of coping, as perceived by the respondent. Taped interviews were coded independently twice, over a 16-month interval. High reliability levels were obtained. Results indicated that returnees had little difficulty adjusting to life with their families except for experiencing some value conflict with them and some lack of privacy. Most of their problems were related to their professional life. In that category they reported that they found some difficulty adjusting to the system as a whole and to their role as professors. Lack of intellectual stimulation, lack of facilities and materials, excessive red tape, lack of opportunity and time to do research was fairly common for most, and they felt these were moderately serious problems. In most cases returnees felt they were coping adequately.
