【“五一”假期休闲旅行绽放新方式 露营经济成消费新风尚】Pendant les vacances de la Fête du travail en Chine, les voyages à travers le pays montrent de nouvelles tendances en raison des restrictions anti-COVID-19. Les Chinois explorent de nouveaux modes de voyage plus proches de chez eux en visitant la campagne ou en faisant du camping. #COVID19# 法语视频报道：https://t.cn/A6XLFIOo
343 发布的 Halo Infinite 第二季的新模式预览：halowaypoint.com/news/season-2-modes-preview
新模式有山丘之王、抢夺领土、最后的斯巴达。前面两个模式二十年不变，没什么好说的。最后的斯巴达是在以前的一些模式中加入些微变化：
BTB 地图
12 人自由对战
5 种预设的起始装备
每人 5 次重生机会
每杀敌一人，会升级为更强的其它武器
缩圈，战至最后一人

Topological modes in a laser cavity through exceptional state transfer
10.1126/science.abl6571
abstract:
"Shaping the light emission characteristics of laser systems is of great importance in various areas of science and technology. In a typical lasing arrangement, the transverse spatial profile of a laser mode tends to remain self-similar throughout the entire cavity. Going beyond this paradigm, we demonstrate here how to shape a spatially evolving mode such that it faithfully settles into a pair of bi-orthogonal states at the two opposing facets of a laser cavity. This was achieved by purposely
||designing a structure that allows the lasing mode to encircle a non-Hermitian exceptional point while deliberately avoiding non-adiabatic jumps.||
The resulting state transfer reflects the unique topology of the associated Riemann surfaces associated with this singularity. Our approach provides a route to developing versatile mode-selective active devices and sheds light on the interesting topological features of exceptional points."
