Study: Superconductivity switches on and off in “magic-angle” graphene（图）
超导 “魔角”石墨烯 超导电子产品
2023/6/8
With some careful twisting and stacking, MIT physicists have revealed a new and exotic property in “magic-angle” graphene: superconductivity that can be turned on and off with an electric pulse, much ...
2022年7月8日，生物所作物功能基因组研究中心和中国农业大学国家玉米改良中心合作，通过共表达转录因子ZmC1 和ZmR2形成的紫胚玉米新种质与高效单倍体诱导系CAU6融合，创制出不受材料背景的影响、简便高效、单倍体鉴别准确率达99.1%的玉米诱导系MAGIC1（Maize Anthocyanin Gene InduCer 1）和升级版MAGIC2，为进一步提升单倍体育种技术应用效率奠定了基础。相...
“Magic-angle” trilayer graphene may be a rare, magnet-proof superconductor（图）
三层石墨烯 防磁超导体 MRI机器 量子计算机

If invisibility cloaks and other gee-whiz apps are ever to move from science fiction to science fact, we’ll need to know more about how these weird metamaterials actually work. Michigan Tech researche...
An accurate analog clock tick-tick-ticks with a constant precision and well known frequency: one tick per second. The longer you let it tick, the better to test its accuracy — 10 times as long corresp...

Mineral magic? Common mineral capable of making and breaking bonds
Mineral magic Common mineral capable of making breaking bonds
2014/8/14
Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth’s deep carbon cycle. They provide energy for the deep biosphere, and may have implicati...
Note on group distance magic graphs $G[C_4]$
distance magic labeling magic constant sigma labeling graph labeling Abelian group
2012/4/23
A \emph{group distance magic labeling} or a $\gr$-distance magic labeling of a graph $G(V,E)$ with $|V | = n$ is an injection $f$ from $V$ to an Abelian group $\gr$ of order $n$ such that the weight $...
We propose blue-detuned optical traps that are suitable for trapping of both ground state and Rydberg excited atoms. Addition of a background compensation field or suitable choice of the trap geometry...

The pygmy dipole resonances (PDR) for even-even nuclei in 8=ming a systematic calculation of the random-phase approximation with the Skyrme functional of SkM*. The calculation...
Anomalous pairing vibration in neutron-rich Sn isotopes beyond the N=82 magic number
neutron-rich Sn Anomalous pairing vibration
2011/7/20
Two-neutron transfer associated with the pair correlation in superfluid neutron-rich nuclei is studied with focus on low-lying $0^+$ states in Sn isotopes beyond the N=82 magic number.
Magic-zero wavelengths of alkali-metal atoms and their applications
Magic-zero wavelengths alkali-metal atoms application Quantum Gases
2011/8/4
Abstract: Using first-principles calculations, we identify "magic-zero" optical wavelengths, \lambda_zero, for which the ground-state frequency-dependent polarizabilities of alkali-metal atoms vanish....
