Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Global large strong solutions to the 2D radially symmetric compressible Navier-Stokes equations on bounded domain
有界域 二维径向对称 可压缩Navier-Stokes方程 全局大强解
2023/12/11
In this talk, I will present our recent result the 2D radially symmetric compressible Navier-Stokes equations with density-dependent viscosity. Under the condition of beta>1, we prove the global exist...
With new experimental method, researchers probe spin structure in 2D materials for first time（图）
2D材料 自旋结构 “魔角”石墨烯
2023/6/26
By observing spin structure in “magic-angle” graphene, a team of scientists led by Brown University researchers have found a workaround for a long-standing roadblock in the field of two-dimensional el...
Using state-of-the-art magnetic imaging, a Cornell-led collaboration has for the first time characterized a key property of the superconducting state of a class of atomically thin materials that are t...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Stable nearly self-similar blowup of the 2D Boussinesq and 3D Euler equations with smooth data
平滑数据 二维布西内斯 三维欧拉方程 稳定近似 自相似爆炸
2023/4/13
Whether the 3D incompressible Euler equations can develop a finite-time singularity from smooth initial data is an outstanding open problem. In this talk, we will first review recent progress in singu...
How “2D” materials expand（图）

Two-dimensional materials, which consist of just a single layer of atoms, can be packed together more densely than conventional materials, so they could be used to make transistors, solar cells, LEDs,...
Scientists capture first-ever view of a hidden quantum phase in a 2D crystal（图）
二维晶体 隐藏量子相 视图 单脉冲光谱技术
2023/6/6
The development of high-speed strobe-flash photography in the 1960s by the late MIT professor Harold “Doc” Edgerton allowed us to visualize events too fast for the eye — a bullet piercing an apple, or...
Physicists find direct evidence of strong electron correlation in a 2D material for the first time（图）
二维材料 强电子 相关性 非常规超导性
2023/6/7
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-f...
When it comes to creating next-generation electronics, two-dimensional semiconductors have a big edge. They’re faster, more powerful and more efficient. They’re also incredibly difficult to fabricate.
A first-of-its-kind study examining the thermal transport properties of a novel material is helping steer the future of two-dimensional hybrid perovskites – a relatively new class of materials with ex...
23 February 2007，It's quite easy to see how simple 3D objects could be created using the principle. For example, if the solution were only applied to the edges, only they would shrink when heated, and...
February 15, 2007，Physicists at the National Institute of Standards and Technology (NIST) have taken the first ever two-dimensional pictures of a “frequency comb,” providing extra information that enh...
Feb. 7, 2007，BOULDER, Colo.—Physicists at the Commerce Department’s National Institute of Standards and Technology (NIST) have taken the first ever two-dimensional pictures of a “frequency comb,” prov...
