Critical Temperature Shift in Weakly Interacting Bose Gas
High performance monte carlo quantum bose gas the scattering
2014/12/22
With a high-performance Monte Carlo algorithm we study the interaction-induced shift of the critical point in weakly interacting three-dimensional |ψ|4 theory (which includes quantum Bose gas). In ter...
改进的mean shift目标跟踪算法
目标跟踪 均值偏移 模板更新 抗遮挡
2013/11/19
提出一种改进的均值偏移（mean shift， MS）目标跟踪算法，用于提高模板漂移和大面积遮挡情况下视觉目标跟踪算法的鲁棒性和准确性。首先判断目标是否存在遮挡现象，当遮挡未发生时，采用原始MS算法跟踪目标，利用选择性分量更新策略对目标模板进行更新，减少模板漂移的影响|当遮挡发生后，利用非对称核函数模型对候选目标模型进行矫正，降低遮挡像素点对MS矢量和目标跟踪稳定性的影响。实验结果表明，改进的跟踪...
Partial Differential Phase Shift Keying - Theory and Motivation
Partial Differential Phase Shift Keying Theory and Motivation Optics
2012/5/29
Recently, many evidences demonstrate that partial Differential Phase Shift Keying (i.e., when the delay inside the Delay Interferometer is shorter than the symbol period) can partially compensate the ...
Deducing radiation pressure on a submerged mirror from the Doppler shift
submerged mirror the Doppler shift Optics
2012/5/29
Radiation pressure on a flat mirror submerged in a transparent liquid, depends not only on the refractive index n of the liquid, but also on the phase angle psi_0 of the Fresnel reflection coefficient...
Phase shift in an atom interferometer induced by the additional laser lines of a Raman laser generated by modulation
atom interferometer additional laser lines of a Raman laser modulation Atomic Physics
2012/5/28
The use of Raman laser generated by modulation for light-pulse atom interferometer allows to have a laser system more compact and robust. However, the additional laser frequencies generated can pertur...
Localization for quasi-periodic Schrodinger operators with dynamics defined by the skew-shift and potential in a Gevrey-class
Mathematical Physics Spectral Theory dynamics quasi-periodic Schrodinger operators
2012/4/16
We consider the discrete one-dimensional Schr\"{o}dinger operator with quasi-periodic potential $v_n := \lambda v (\shift^n \, \xx)$, where $\shift : \T^2 \rightarrow \T^2, \, \shift \xx := (x_1+x_2, ...
Soliton self-frequency blue-shift in gas-filled hollow-core photonic crystal fibers
self-frequency blue-shift photonic crystal fibers
2011/9/7
We show theoretically that the photoionization process in a hollow-core photonic crystal fiber filled with a Raman-inactive noble gas leads to a constant acceleration of solitons in the time domain wi...

Lamb Shift static atoms Schwarzschild black hole
2010/12/23
We study, by separately calculating the contributions of vacuum fluctuations and radiation reaction to the atomic energy level shift, the Lamb shift of a static two-level atom interacting with real ma...
The pion-pion scattering phase shift is computed using LapH propagators. The LapH method for computing quark propagators is used to form two-particle correlation functions with a number of different o...

percolation thresholds epidemic spread static dynamic small-world networks
2010/11/16
The aim of the study was to compare the epidemic spread on static and dynamic small-world networks. The network was constructed as a 2-dimensional Watts-Strogatz model (500x500 square lattice with ad...

2010/11/12
We have measured the AC-Stark shift of the $14D_{5/2}$ Rydberg state of rubidium 87 in an optical dipole trap formed by a focussed CO$_2$-laser. We find good quantitative agreement with the model of ...
