2014/12/20
We study the performance of Monte Carlo simulations that sample a broad histogram in energy by determining the mean first-passage time to span the entire energy space of d-dimensional ferromagnetic Is...
提出两个二能级原子纠缠态的隐形传态方案,方案中选用由四个全同二能级原子组成的非最大纠缠Cluster态作为量子信道.研究表明,接收者根据发送者传送的经典信息,通过引入一个附加原子并实施相应的幺正变化,即可以一定的概率重构原子态,此概率由Cluster态中绝对值最小的两个系数决定.该方案中使用的是Cluster非最大纠缠态作为量子信道,因此与其他方案相比该方案可以节约更多的纠缠资源和经典信息.如果使...

Abstract: In finite-size scaling analyses of Monte Carlo simulations of second-order phase transitions one often needs an extended temperature range around the critical point. By combining the paralle...
Alpha-Cluster Model, Charge Symmetry of Nuclear Force and Single Particle Bound State Potential in Symmetrical Nuclei
Alpha-Cluster Model Nuclear Force Bound State Potential
2011/7/20
A phenomenological alpha-cluster model based on the charge symmetry of nuclear force allows one to estimate the last proton position radius (LPPR) in a symmetrical nucleus. The values of LPPR obtained...
