A high order energy preserving scheme for the strongly coupled nonlinear Schrōdinger system

A high order energy preserving scheme for a strongly coupled nonlinear Schrōdinger system is roposed by using the average vector field method. The high order energy preserving scheme is applied to simulate the soliton evolution of the strongly coupled Schrōdinger system. Numerical results show that the high order energy preserving scheme can well simulate the soliton evolution, moreover, it preserves the discrete energy of the strongly coupled nonlinear Schrōdinger system exactly.

Analysis and Simulation of Quantum Radar Cross Section

We derive a modified analytical expression of a quantum radar cross section （QRCS）. Subsequently, we present a comparison between the QRCS and a classical radar cross section （RCS） and analyze the factors that can affect the intensity of the peak and side lobes. Simulation results on a flat rectangular plate demonstrate that QRCS has a similar structure to that of RCS. The analysis of side-lobe structure can benefit the design of quantum stealth platforms as well as the research on quantum radars.     

Result of search for low velocity exotic particles

The L3＋C experiment, taking advantage of the L3 muon magnetic spectrometer, measured the spatial tracks of charged cosmic ray particles to obtain rigidity as well as velocity. One possible low velocity exotic particle is observed. The existing uncertainties are discussed, and the flux upper limit of the low velocity exotic particles from this observation is deduced based on the assumption of a null observation. The result is 6.2×10^-10 cm^-2·s^-1·sr^-1 at 90% confidence level in the velocity range from 0.04c to 0.5c.

跳圈实验的启示

楞次定律是电磁感应中一个十分重要的定律,然而,笔者却发现目前教科书中有关楞次定律的表述与跳圈实验不完全相符.我认为,该定律的描述存在缺陷,需要纠正.2012年笔者又仔细地重做了跳圈实验,实验结果是成功的,再次证实了楞次定律的描述存在问题.现把这个实验的情况及笔者的分析介绍给大家.笔者实验的目的是要观察跳圈(实际就是几个铝和铜的闭合线圈)在下述几种情况下的运动,
