MIT physicists and colleagues have discovered the “secret sauce” behind some of the exotic properties of a new quantum material that has transfixed physicists due to those properties, which include su...
With a little twist and the turn of a voltage knob, Cornell researchers have shown that a single material system can toggle between two of the wildest states in condensed matter physics: the quantum a...
近日，南华大学核科学技术学院硕士研究生李诗铭同学在其导师毛飞副教授的指导下在物理学国际权威期刊《Physical Review B》上发表题为《First-principles study of the electronic stopping power of indium for protons and He ions》的学术论文。《Physical Review B》是凝聚态物理学和材料物理学...
Wakanda, the mythical setting for Marvels’ superhero film “Black Panther,” is home to some not-so-mythical technology. An indestructible cape might not yet be possible, but Wakanda’s levitating high-s...
Planckian metals have the potential to power high-temperature superconductors, quantum computers and a host of other next-generation technologies. However, these “strange” metals – in which electrical...
近日，东南大学物理学院马亮和王金兰教授团队基于先进的多尺度模拟方法，在二维材料成核与生长机理的理论研究方面取得重要进展，与南京大学王欣然实验团队合作成功实现了晶圆级(2英寸)二硫化钼(MoS2)单层单晶薄膜的生长制备。研究成果以“Epitaxial growth of wafer-scale molybdenum disulfide semiconductor single crystals on...
“Magic-angle” trilayer graphene may be a rare, magnet-proof superconductor（图）

MIT physicists have observed signs of a rare type of superconductivity in a material called magic-angle twisted trilayer graphene. In a study appearing today in Nature, the researchers report that the...
In 1934, physicist Eugene Wigner made a theoretical prediction based on quantum mechanics that for decades years went unseen.
Uppsala University in Sweden has been a valuable partner to CERN since the Laboratory’s foundation. In the 1950s, Uppsala, having just constructed its own cyclotron, contributed to the development of ...
Physicists from across three continents report the first experimental evidence to explain the unusual electronic behavior behind the world’s thinnest superconductor, a material with myriad application...
Cornell researchers have discovered a rare “pseudogap” phenomenon that helps explain how the superconducting transition temperature can be greatly boosted in a single monolayer of iron selenide, and h...
Researchers from Cornell’s School of Applied and Engineering Physics and Samsung’s Advanced Institute of Technology have created a first-of-its-kind metalens – a metamaterial lens – that can be focuse...
An interdisciplinary team of Cornell researchers has taken its breakthrough discovery – which melded the ability of soft organic materials to spontaneously self-organize with quantum materials to crea...
新研究首次发现磁涡环（图）
磁涡环 磁铁 磁性材料
2020/12/1
磁铁往往隐藏着美。就一个冰箱贴而言：它的一面有“粘性”，另一面却没有，这多少有点出乎我们的意料。其秘密在于磁化在材料内部以一种明确的方式排列。而更复杂的磁化纹理是许多现代技术的核心，如硬盘驱动器。现在，一个国际团队报告了在由磁性材料钆钴制成的小柱子内意外发现磁性结构。近日，科学家在刊登于《自然—物理》上的一篇论文中写道，通过观察亚微米的环状结构，他们将其确定为磁涡旋环。这些纹理远远超出了它们的美学...
