Origin And Evolution Of Energetic Particle Populations In The Magnetosphere
Constant current ions electrons magnetosphere ionosphere solar wind
2017/3/23
There is a constant flow of electrons ions and into and out of the magnetosphere and the intricacies of the magnetosphere determine the paths that these particles take through it. Although the plasma ...
The Cusp as a Source of Magnetospheric Particles
Satellites plasma the solar wind magnetic sheath origin diamagnetic cavities the dipole field
2017/3/23
Observations made by a number of satellites have shown that plasma of solar wind/magnetosheath origin enters the high altitude polar cusp creating diamagnetic cavities of large dimensions. The Earth's...
对传统光滑粒子动力学(SPH)方法进行修正,提出了一种密度初始化方法,同时采用一种新的固壁边界处理方法,模拟溃坝问题。通过液滴旋转和无透空块体溃坝问题的模拟验证了修正SPH方法的有效性和在自由表面模拟中的准确性,分析了密度初始化对流动的影响;数值结果表明,修正SPH方法提高了数值计算的精度和稳定性。最后应用修正SPH方法模拟了有透空块体和挡板紧挨水柱的溃坝现象,比较了有无透空块体两种情况下右端直墙...
Lattice field theory is a useful tool for studying strongly interacting theories in condensed matter physics. A prominent example is the unitary Fermi gas: a two-component system of fermions interacti...
Scaling study for 2 HEX smeared fermions: hadron and quark masses
Scaling study 2 HEX smeared fermions hadron
2011/1/6
The goal of this study is to investigate the scaling behaviour of our 2 HEX action. For this purpose, we compute the $N_f=3$ spectrum and compare the results to our 6 EXP action. We find a large scali...

Experimental and Physics Prospects at ATLAS and CMS - 2011 and Beyond
Experimental Physics Prospects ATLAS CMS - 2011 and Beyond
2011/1/5
The ATLAS and CMS experiments have collected data at the CERN Large Hadron Collider (LHC) since December 2009, and with a collision energy !s=7 TeV since March 2010. Both detectors work remarkably wel...
There has been significant interest in the last several years in studying possible gravitational duals, known as Lifshitz spacetimes, to anisotropically scaling field theories by adding matter to dis...
Shock Wave Collisions and Thermalization in AdS_5
Shock Wave Collisions Thermalization AdS_5
2010/12/22
We study heavy ion collisions at strong 't Hooft coupling using AdS/CFT correspondence. According to the AdS/CFT dictionary heavy ion collisions correspond to gravitational shock wave collisions in A...
The virial relation for compact Q-balls in the complex signum-Gordon model
compact Q-balls complex signum-Gordon model
2010/12/22
In this work the properties of Q-balls in the complex signum-Gordon model in $d$ spatial dimensions is studied. We obtain a general virial relation for this kind of Q-ball in the higher-dimensional s...
Three-point correlation functions from semiclassical circular strings
Three-point correlation functions semiclassical circular strings
2010/12/22
The strong-coupling limit of three-point correlation functions of local operators can be analyzed beyond the supergravity regime using vertex operators representing spinning string states. When two of...
We review recent results on hadron form factors and nucleon generalized parton distibutions obtained with dynamical lattice QCD simulations. We discuss lattice artifacts and open questions, and presen...
Can accretion disk properties observationally distinguish black holes from naked singularities?
accretion disk properties black holes naked singularities
2010/12/20
Naked singularities are hypothetical astrophysical objects, characterized by a gravitational sin-gularity without an event horizon. Penrose has proposed a conjecture, according to which there exists a...

New Physics MeV Neutrino Sources Brighter a Thousand Suns
2010/12/27
Short baseline oscillations of neutrinos (nue and nuebar) due to active-sterile (a-s) mixing can be observed explicitly using MeV neutrino beams and existing/planned neutrino detectors. The typical ba...

2010/12/20
In Einstein-aether theory and Horava gravity, a timelike unit vector is coupled to the spacetime metric. It has previously been shown that in an exponentially expanding homogeneous, isotropic backgrou...
