Perturbation Theory for Fractional Brownian Motion in Presence of Absorbing Boundaries
Perturbation Theory Presence of Absorbing Boundaries
2010/11/25
Fractional Brownian motion is a Gaussian process x(t) with zero mean and two-time correlations
hx(t1)x(t2)i = Dt2H 1 + t2H 2 jt1 t2j2H, where H, with 0 < H < 1 is called the Hu...

Temperature driven structural phase transition for trapped ions and its experimental detection
Temperature driven structural phase transition trapped ions experimental detection
2010/10/21
A Wigner crystal formed with trapped ion can undergo structural phase transition, which is
determined only by the mechanical conditions on a classical level. Instead of this classical result, we show...
Tripartite thermal correlations in an inhomogeneous spin-star system
Tripartite thermal correlations inhomogeneous spin-star system
2010/10/20
We exploit the tripartite negativity to study the thermal correlations in a tripartite system, that is the three outer spins interacting with the central one in a spin-star system. We analyze the depe...

2010/10/19
We present results establishing a link between unitary relaxation dynamics after a quench in closed manybody systems in non-equilibrium and the entanglement in the energy eigenbasis. We find that even...

2010/10/21
The transitory and stationary behavior of a quantum chaotic ratchet consisting of a biharmonic
potential under the effect of different drivings in contact with a thermal environment is studied.For we...

We report heating rate measurements in a microfabricated gold-onsapphire surface electrode ion trap with trapping height of approximately 240 m.Using the Doppler recooling method, we characterize the...
Lattice Heat Capacity of Mesoscopic Nanostructures
Lattice Heat Capacity Mesoscopic Nanostructures
2010/10/27
We present a rigorous full quantum mechanical model for the lattice heat capacity of mesoscopic nanostructures in various dimensions. Model can be applied to arbitrary nanostructures with known vibrat...
In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator wo...
Polymer heat transport enhancement in thermal convection: the case of Rayleigh-Taylor turbulence
Polymer heat transport thermal convection
2010/4/1
We study the effects of polymer additives on turbulence generated by the ubiquitous Rayleigh-Taylor instability. Numerical simulations of complete viscoelastic models provide clear evidence that the h...
Recently it has been suggested that an enhancement in the visibility of ghost images obtained with thermal light can be achieved exploiting higher order correlations 1. This paper reports on the statu...

旋涡式低NOX煤粉燃烧器燃烧特性的数值模拟
低NOx排放 煤粉燃烧器 旋涡
2009/11/4
在冷态实验和数值研究的基础上，采用STAR-CD软件对旋涡式低NOx煤粉燃烧器进行了热态模拟，分别得出了燃烧器内还原区和燃尽区的燃烧特性. 还原区流场呈涡旋状，颗粒处在高速旋转、燃烧、破碎的状态，其内严重缺氧，温度较低且分布均匀. 燃尽区内氧气浓度相对较高，温度较高，有利于颗粒的燃尽. 对于0.5 mm以下颗粒，本燃烧器能够稳定地燃烧，并得到较低的氮氧化物排放. 对燃烧器优化设计的计算结果表明，将...
利用热带测雨卫星（TRMM）携带的测雨雷达（PR）、闪电成像仪（LIS）和微波辐射计（TMI）的同步探测资料，选取1998—2008年登陆中国的46个热带气旋，分析了其不同强度阶段的闪电活动、雷达反射率和冰散射信号的分布特征，以及闪电的发生与雷达反射率和冰散射信号之间的关系。
