小球穿墙而过,诺奖看见“量子革命”
2 1 Shi Ji Jing Ji Bao Dao· 2025-10-10 07:56
为"普适量子论"的天平再压下有力量的一格。 当小球以单个粒子形态存在时,这一看似不可能的现象成为可能,它就是"量子隧穿", 是一种量子力 学现象。 量子力学通常用来解释微观世界现象,如单个粒子、原子或电子的行为。当系统变得越来越大,粒子越 来越多时,量子效应就会被各种相互作用破坏掉,变得几乎看不见。 例如,一个由众多分子组成的小球不会表现出量子力学效应,球每次都会撞到墙上反弹,这就是人们熟 悉的宏观世界。 想象一下,有一颗小球,放在被墙分隔为左右两侧的房间里。按常理,它们只能在自己这一侧滚动,除 非有人在墙中开一个洞。但小球忽然无声无息地出现在墙的另一边:没有门、没有钥匙,墙也完好无 损,小球却完成了过墙。 让量子现象肉眼可见 今年获得诺贝尔物理学奖的三位物理学家约翰·克拉克(John Clarke)、米歇尔·德沃雷(Michel H. Devoret)和约翰·马丁尼斯(John M. Martinis)就在实验中证明,量子隧穿并不只属于微观世界,也可 以出现在由无数粒子组成的宏观尺度系统中。即特定条件下,原本只在微观世界中存在的量子现象,在 宏观尺度上展现了出来。 (约翰·克拉克、米歇尔·德沃雷和约翰·马丁 ...

川普公开宣告:稀土到不了美国就加征200%关税!可惜威胁不了中国
Sou Hu Cai Jing· 2025-10-02 05:02
"吃中国的饭,还要砸中国的锅?"——这句话或许正好点出了当前的尴尬局面。 据路透社报道,G7成员国和欧盟正在酝酿一系列针对中国稀土产业的限制 措施。他们计划设定稀土价格下限、对部分中国稀土产品加征关税,甚至打着环保旗号征收所谓"碳税",试图削弱中国的价格优势,同时占据"道德高地"。 知情人士透露,G7内部还在讨论更多办法:比如提高外国资本投资中国关键矿产企业的门槛,避免资金流入中国;再比如设定稀土进口配额,限制从中国 采购的数量,迫使成员国更多依赖本土或"友好国家"的稀土。 西方的担忧与分歧 今年4月,中国对钐、钆、铽等关键稀土元素实施出口管制。中国方面强 调,这是为了保护资源、维护环境,属于国际通行做法。但在西方眼中,这被解读为可能"切断供应链"的信号。于是,在G7的"关键矿产计划"会议上,各国 提出上述对华限制,核心目的就是削弱中国在全球稀土链上的主导地位。 然而,内部意见并不统一。 - 美国最为强硬,积极推动设定价格下限和加征关 税。数据显示,中国收紧管控后,美国进口稀土磁铁的审批率骤降至42%,军工和高科技产业都出现原料紧缺。甚至在阅兵前夕,特朗普还威胁:"如果中 国不保证稀土磁铁出口,美国将对所有中 ...
