Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Metric geometric aspects of Einstein manifolds
Einstein流形 度量几何 爱因斯坦流形 黎曼几何
2023/11/29
This lecture concerns the metric Riemannian geometry of Einstein manifolds, which is a central theme in modern differential geometry and is deeply connected to a large variety of fundamental problems ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Global stability of the Minkowski spacetime for the Einstein-Vlasov system
爱因斯坦-弗拉索夫系统 闵可夫斯基时空 全球稳定性
2023/4/21
In this talk, we discuss the global stability of the Minkowski spacetime in the wave coordinates system for the massive Einstein-Vlasov system. In particular, compared with previous results by Lindbla...
Stokes-Einstein(SE)关系的失效是液体玻璃化转变过程中的特征动力学行为之一，其背后的物理机制一直是凝聚态和非平衡统计领域近些年的热议话题。研究表明，在液体玻璃化过程中，玻璃转变点附近异常缓慢的动力学行为，以及实验系统中可能的微小晶粒析出相都有可能对体系扩散系数与弛豫时间（或黏滞系数）之间的耦合关系产生影响；这种扩散系数与弛豫时间之间的退耦合现象也可从热力学的角度加以理解，例如在相空...

Astronomers evidence Einstein theories star orbiting massive black hole
2019/10/22
More than 100 years ago, Albert Einstein predicted that light is deflected by extremely massive objects, but there is no way to test such powerful effects on Earth. Instead, astronomers turn their att...

faster way make Bose Einstein condensates
2017/12/18
The world of an atom is one of random chaos and heat. At room temperatures, a cloud of atoms is a frenzied mess, with atoms zipping past each other and colliding, constantly changing their direction ...

Scientists ditch approximations modeling universe Einstein’s full theory General Relativity
2016/7/4
Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of...
Gravitational Waves Detected 100 Years After Einstein’s Prediction
Gravitational Waves Detected 100 Years After Einstein’s Prediction
2016/2/23
For the first time, scientists have observed ripples in the fabric of spacetime, called gravitational waves, arriving at the
earth from a cataclysmic event in the distant universe. This confirms a ma...
BOSE–EINSTEIN CONDENSATION BEYOND MEAN FIELD:MANY-BODY BOUND STATE OF PERIODIC MICROSTRUCTURE
Bose–Einstein condensation homogenization many-body perturbation theory two-scale expansion singular perturbation mean field limit bound state
2015/10/16
We study stationary quantum fluctuations around a mean field limit in trapped, dilute atomic gases of repulsively interacting bosons at zero temperature. Our goal is to describe quantum-mechanically t...

This is a correction to the author’s article [Multiscale Model. Simul.,10 (2012), pp.383–417].
BOSE-EINSTEIN CONDENSATION AT FINITE TEMPERATURES:MEAN FIELD LAWS WITH PERIODIC MICROSTRUCTURE
quantum dynamics Bose-Einstein condensation periodic homogenization finite temperatures two-scale expansion mean field limit
2015/10/16
At finite temperatures below the phase transition point, the Bose-Einstein condensation, the macroscopic occupation of a single quantum state by particles of integer spin, is not complete. In the lang...
The Einstein universe is the conformal compactification of Minkowski space.
It also arises as the ideal boundary of anti-de Sitter space. The purpose of this article is
to develop the syntheti...
Bose-Einstein condensation of tunnelling photons in the brain cortex as a mechanism of conscious action
Quantum brain dynamics (QBD) consciousness
2015/7/30
Mind is supposed to be a macroscopic quantum wave governing the dynamics of the quantum coherent cytoskeletal protein system inside the cytoplasm of the brain cortical neurons. Its dynamical timescale...
ANALYSIS OF A BOSE-EINSTEIN MARKOV CHAIN
Convergence rate markov chain stationarity k arcsine
2015/7/8
This paper gives sharp rates of convergence to stationarity for a Markov chain generating Bose-Einstein configurations of n balls in k boxes. The analysis leads to curious identities for the arc...
