单分子 二极管
2015/5/27
美国哥伦比亚大学应用物理学副教授拉莎·文卡塔拉曼指导的研究团队开发了一种新技术，成功创建出首个单分子二极管，其性能比之前所有设计的要高50倍，有望在纳米器件领域获得实际应用。论文发表在5月25日的《自然·纳米技术》杂志上。单分子器件是电子设备微型化的极致。亚利耶·艾佛莱姆和马克·瑞特在1974年提出，单个分子可以作为整流器，一个单向的电流导体。此后，科学家相继演示了单分子连接到金属电极上（单分子结...

万有引力 常数变化周期 5.9年
2015/4/23
牛顿万有引力常数G，在过去40多年中被测量过多次，但是由于偶然和系统性的错误，测量结果间的差异比我们预想的要大得多。现在，科学家发现G值随时间每5.9年有一个振荡周期，他们认为G值变化跟测量本身没有关系，一定还有别的因素在影响着测量结果。
Traditionally, particle accelerators have relied on electric fields generated by radio waves to drive electrons and other particles close to the speed of light. But in radio-frequency machines there i...
量子雷达可探测低反射率目标
量子雷达 低反射率目标
2015/4/15
由英国约克大学量子信息科学家领导的一个国际研究小组开发出一种量子雷达原型，有望探测到那些传统系统看不见的目标。相关论文发表在近期的《物理评论快报》上。据物理学家组织网近日报道，他们开发的新一代雷达是个混合系统，能利用微波与光束之间的量子相关性来探测物体，如癌细胞或隐形飞机这类低反射率目标。由于量子雷达运行耗能比传统系统要低得多，因此从长远来看，在广泛的生物医学领域，如非入侵性核磁共振扫描，有着巨大...
双原子干涉实验首获成功
双原子 干涉实验
2015/4/15
距科学家们成功实现双光子干涉实验之后30年，法国物理学家首次成功进行了双原子的干涉实验。这一研究将大力促进量子计算机和量子网络的发展。在最新研究中，法国国家科学研究院（CNRS）和巴黎十一大学的物理学家首次成功地让两个独立的原子实现了相干：当他们朝一个半透明镜子的两边发射不可区分原子对时发现，原子对总是形影不离地同时出现。30年前，科学家们使用光子进行了同样的实验。由于与光子相比，原子是大质量粒子...
